Here is my latest attempt at Jupiter and the GRS.
Taken with a ToUcam pro CCD and DS-90EC
at prime focus with a 2x barlow.

The skies here in Wales aren't clear that often, but Saturday
morning they were great.
For each image I took 4 sets of 50 shots each at different camera
settings ( Logitech Quickcam Web). I put each set of 50 through
AstroStack, which left me with 4 images. I then put those 4 images back
through Astro Stack to get the result images.
Thanks again for the great site!

Saturne/Jupiter ETX 125 EC et caméra Vesta pro Alain Bouchez, France |
AblesS@usa.redcross.org (Ables, Steven, G) [13 Dec 01] |
Just wanted to send you a couple of photo's I took last night for the
gallery. The pictures were taken with my ETX-70AT and a 9mm Plossl using
Scopetronic's wonderful Digi-T adapter along with my Olympus C-2040Z. The
first shot is a composite. Jupiter's moons were a single frame with a 1
second exposure. To be honest, the first shot was an accident. I forgot to
change my exposure time and didn't realize until later that I had captured
two moons. Had I done it on purpose, I would have got all four moons !
Jupiter itself is a stack of 18 images using Astrostack resampled X1 with
unsharp mask. Jupiter was copied and pasted over the overexposed Jupiter on
the original. The second image is a stack of 22 images resampled X2 with
unsharp mask. These are not as fancy as many of the images I've seen, but it
does show what can be done with this small scope even though planets are not
it's strong point.

There is a pic of saturn attached. It was my first attempt with the ETX-90EC
and a modified
Quickcam Pro 3000. I'm satisfied but I think I can do better. The pic was
taken one day before saturns occultation. I shot more than 100 pics and I
think this pic was my best from them.

Thought I would share my experience with you, along with a few pics:
At 4:00 p.m., I arrive at home (Gatineau, Quebec) from work (Ottawa, Ontario) and decide to look at the
satellite pictures. The Canadian Meteorological Centre was predicting cloudy skies all over, but
the satellite pictures seemed to indicate that there might be a
clearing around Kingston at the right moment. I called Pierre Martin,
and he decided to join me. I then packed up the car and went to pick
him up.
After joining at the museum of science and tech., we go south on HWY
31, then turned west to get the 416. As soon as we turned west,
whatever rain that was falling stopped. later, after reaching the 401
and heading west, we started to see some clearings.
At about 60km from Kingston, (around exit 670), we notive large
clearings in the sky. We happened to notice a Tim Horton's on the
other side, went for a few more kilometers, and decide to turn back
to install in the parking lot. How convenient! A Tim Horton's at our
observing site. AAhhhh, paradise!
We arrive there about 30 minutes before the occultation, and the
skies were clearing. I set up my ETX 125 with the QuickCam, and
Pierre set up mu camera with a 200mm telephoto lens.
At the prescribed time, we saw the occultation. I recorded a video of
it, from which I extracted the photos
We noticed that the final disappearance (last contact) occurred at
19:53:05 EST (00:53:05 UT), plus or minus 5 seconds. The
coordinates were (on the GPS) 44 degres 30 minutes 17.60 seconds
north, 75 degres 50 minutes 12.62 seconds west.
We stayed to witness the re-appearance, and about three minutes
before the predicted time, a man and his son came by to watch.
Unfortunately, the cloud cover had started only 2 minutes before re-
appearance, and we didn't get to notice it. The man seemed genuinely
interested, and mentionned that he wanted to buy a telescope for his
son for Christmas. We referred him to our Yahoo! newsgroup (OAOG), and hope to
talk to him soon!
On our way back, the sky was overcast, and by the time we got back to
Ottawa, we were travelling in pea-soup fog.
I dropped Pierre off next to his car, and headed home.
Well, that was it.
Enjoy the Pics!

After the webcam, I have tried the digital video camera : not bad, I am
quite glad that the Cassini Division, clearly seen visually, came out in the
picture. The sky was hazy, it has been raining for weeks here, I surely hope
that when the monsoon goes, it will be spectacular.

Didn't see any pictures using a DS90 on your site yet, so I thought I
would send you these of Saturn.
Picture #1 (left) was made using a DS90 and Greyscale Quickcam at prime-focus
with a 2x barlow. 10 images stacked
in Photoshop on my G4.
Picture #2 (right) was made using a DS90 and Canon Powershot350 digital camera
held up to a 6.5 eyepiece.
I am still working on getting my techniques down - your website has been
very encouraging.

Great Site. I own an ETX125, and love every bit of it,
especially the Autostar.
Anyway, I connected my Logitech Webcam Express on the
scope at prime focus, and got a shot of Saturn just
before occultation in Ottawa, CANADA, at about 9:20. I
played with the colour levels and contrast/brightness
to bring out Saturn, and there are a couple of
artifacts because the camera was a bit dusty, but I'm
very pleased with the image.
Next time, I will make a video of it, with the audio
recording the time signal on my shortwave radio as the
QuickCam takes the pictures. Should be interesting.

Here is a pic I took of the Occultation of Saturn and the Moon on Sept. 10 at about 9:14 AM as viewed from here in Winchester VA. I took the pic using my Pentax KX at prime focus, and although Saturn was easily seen through an eyepiece I'm not surprised that it didn't show up on film well do to my inexperiance, (This was my first attempt at Prime focus photograghy) and the bright blue skies in the background. I put an arrow in the pic to point it out, but if you are not familiar with what Saturn would look like next to the moon it will be hard to see.. If anyone can see it let me know. I can pick it out, but then I took the pic..
I love the mighty ETX site, and it has helped me alot.

i have seen your etx side on the web. It's very nice and usefull. I'm an
expierenced
amateur astronomer. I own some telecopes from 6cm Refractor to 28cm (C11), a
Schmidtkamera
(200mm Main Mirror, Corrector 157mm and focus is 257 mm), a Videocamera and
the ST5 CCD.
My newest Telescope is an ETX 90 with Autostar. I've seen some pictures taken by the ETX 90, some are very good indeed. I'll send you a Jupiter picture taken on January 14 this year with a Sony Videocamera (older modell, automatic an 0.3 LUX sensutiv) and the C11. This picture was image processed by "giotto". Giotto can work with Videostreams (or If you have an AVI-Video) and do a lot of work fully automatically. Gitto adds the Videopictures automatically. I sink this can be very usefull for yours too. Look here for downloading the software! www.geocities.com/georgdittie/giotto.htm The software is freeware, but in german ! |

I love your site! It's a great place to learn about what can be done with
this marvelous little telescope.
I've had my ETX-90 EC since September '99, and have enjoyed every minute of it. I thought you would be interested in some photos I've taken with the scope. Digital Camera: Sceptre SVC 300 CMOS color in eyepiece holder (I modified the camera by removing its swiveling base and lens, thereby exposing the CMOS chip, and supergluing to the camera a plastic film canister which had had its bottom cut out, allowing the camera to be slipped into the eyepiece holder.) www.sceptre.com/Products/PCCamera/svc300.htm Exposure: AstroStack enhanced composite of approx. 80 images Clayton, NC For the record, all the photo's I've sent you were taken with the Meade ETX-90 EC. Hope you like them. Thanks! |

Here are my first attempts at Mars with my ETX90EC. I took these with an

26mm+2x barlow eyepiece in a North Chicago Suburb on June 21 at about
11:00p.m.

tcredden@bellsouth.net (Clay Redden) [3 Jul 01] |
Took these photos of Mars about 9:00 p.m. (7-1-01). I had to shoot
through haze, heat, and high humidity here in Central Alabama. I'm lucky
I'm getting any usable pictures. I shot these with an Olympus C3030Zoom
attached to the ETX-125 with a 15mm eyepiece. Exposure was 1/13th of a
second at F2.8 with an ISO 100 setting and photo quality set at
HQ. Although reduced from the original image size to bring out a little
more detail, no other enhancements were made. As with my previous shots of
Saturn and Jupiter, the ETX wasn't tracking. |

I sent you a mars movie some days ago ( and you post it, thanks! ). Now I have another movie showing a bigger mars and also more detail. The setting is the same: Sony Hi8 handycam + ETX125 + Meade SWA 13.8mm plossl. I set the handycam in its own tripod and it is dificult to have mars in the camera finder. When the camera zoom is used mars easily fills the camera FOV!. That can't be done in the ETX with any eyepiece/barlow combination. ( As you can find in the eyepiece simulator )
Of course the image quality is not good at high magnification but you can actually observe surface detail in the video.
Video was taken last June 10 from my backyard ( N 25 21' , W 99 50' )

Here is a photo that I took of Mars early (about 1a.m.) the other
morning from the street in front of my home in Livermore, CA. Here are
the specs:
- Mars at approximately 25 degrees ALT. - ETX-125 (it didn't take me long to upgrade from my ETX-70). - Afocal eyepiece projection, Meade 9.7mm Plossl series 4000. - Coolpix 990 using Scopetronix eyepiece adapter. - Full zoom, macro auto focus mode. - ISO equivalent 100. - f4.0, 1/4s manual exposure setting. - Remote USB trigger cable. - XVGA resolution, fine image compression. - Selection of 24 best images from 84 taken continuously at 2 per second. - Images aligned and averaged with AstroStack. - RGB channels separated and fine-aligned to compensate for atmospheric dispersion in vertical axis using Photoshop. Thanks again for your great effort on the ETX site! |

Mars - Taken with an ETX125 and a QuickCam pro. Processing is with AstroStack. Mars was very low and the atmosphere turbulent. I also overexposed too much. I know I can do better but I am pleased with this as a first attempt. June 9th, 2001 Clive Jones (Winnipeg, MB) |

I'd appreciate it if you'd post this image on your web site. This is the
first chance I've had to image Mars - I just wish it was higher than 20
degrees above the horizon.
The image is the result of stacking the best 50 of 150 images taken using a
polar-aligned ETX-90 (without AutoStar) with a #126 Barlow, an extension
tube and an old Connectix QuickCam Color.

tcredden@bellsouth.net (Clay Redden) [18 Feb 01] |
I've enjoyed your website for more than a year and I wanted to show what
you can capture even when the telescope is NOT tracking and if you don't
have any photo stacking-enhancement software. Your finderscope setup has to
be pretty accurate so you can "lead" the planets in order to snap the
picture as they track across the eyepiece. I realize this isn't the best
way to do astrophotography but it shows what you can do on the
spur-of-the-moment. These eyepiece projection photos were taken with an
Olympus C-3030Zoom digital camera and a 15mm eyepiece attached to an
ETX-125. Exposure for the Jupiter photo was 1/20th of a second, while the
Saturn photo was taken 1/4th of a second. Absolutely no enhancements were
made to either picture.

First let me compliment you on a great sight with many informative contributors. You provide a great service (investing significant personal time). Your site embodies the fulfillment of the promise of the Web as an information and social conduit. I'm a long time Graphic Arts (Mac :) ) programmer who was the beneficiary of both an Etx 90 and a Nikon CoolPix 880 over Xmas - a great combination for planetary viewing and photography. In Santa Rosa (Ca) we've had a relatively dry Dec & Jan which has been outstanding for introducing a novice like me to the Winter Skies. For the first several weeks we left the scope in a nonEquitorial mount and simply acquainted ourselves with the skies to get our bearing. In early January we graduated to an Equatorial mount in conjunction with an Autostar alignment and have found that it has accelerated our familiarity with the relative positions of objects. This is somewhat contrary to some of the thoughts I've read from the more seasoned sky watchers who often warn against the ease of use of computerized finding/tracking devices like Autostar. My guess is that anyone who is really interested in tracking celestial objects will be looking up even when no scope is available. That seems like motivation enough to learn your way around apart form AutoStar. Anyway enough on that I've got a couple of pictures to share. I'm sending a montage of two pictures Saturn and Jupiter taken on Feb 5th, 2000 using the Coolpix 880 and the Etx 90. My setup was as follows: Feb 25, 2001 (Nikon 880 / Etx 90) - GMT 04:00 (approx) Saturn - Jupiter - 35 exposures (Saturn) / 42 exposures (Jupiter) - AutoStar enabled tracking to keep the Planet in the neighborhood while shooting. - Deluxe Field Tripod unextended (as much as possible after alignment) with no secondary clamps or rubber feet etc) - Scopetronix 25 mm Plossl using the 28mm step Ring adapter (I also use a Nikon ring to 28mm) in conjunction with Scopetronix Eyepiece Projection Camera Adapter. home.att.net/~celestron/digital.htm. - Camera Manual Settings: - Aperture f/4.2, Zoomed in max (2.5X Optical). - ISO 400 - Eposure time was 1/4 sec(Saturn) / 1/8th sec (Jupiter) using the 10 second timer to dampen my unsteady "click".(BTW this camera allows up to 60 second exposures). - no optical filtering - All pictures were taken at a resolution of 2048 X 1536 at the Fine Quality - this is a slightly lossy Jpeg compression (my guess around 80-90 on the PhotoShop scale) / my other option is Tiff but I only have a 64 meg Flash Card so it would fill quickly ... maybe someday I'll have a 250 meg or - Stacked via the Windows app AstroStack using defaults for Unsharp Masking and Deconvolve. Minor Levels adjustment in photoshop (on the Mac). - The evening was warm and the atmosphere steady. |
a.hatwood@net.ntl.com (a.hatwood) [3 Feb 01] |
I invested in a Quickcam Web which has a resolution of 640 x 480,
but also uses a CCD, instead of a CMOS chip. I find it gives clearer
images than the Quickcam Express I was using.
These images were all compiled using Astrostack, from around 80 shots
taken through an ETX-125EC.
The "Jovian system" image was created by first over exposing Jupiter to
reveal the moons, and taking a set of shots, then taking another set of
images with Jupiter exposed properly. The images were then processed,
and one superimposed on the other.
Thanks again for the great site.

I joined the 4504 egroup: http://www.egroups.com/group/Meade4504Telescopes that I learned about here. Rick Krejci's pictures are quit spectacular. Im fixin to send 3 more pics from my 4504. i wont be hurt if you dont post. Just wanted to let you know Im still tweaking. Thanks again for you effort on this great site. -Evan |

I wanted to share with you this picture of Jupiter I took yesterday night
with my ETX90 and the Phillips ToUcam Pro webcam...
I took a small avi and selected the best 150 pictures out of the 963 frames.
All the processing was done using Iris (addition of the 150 pictures /
unsharp mask) I also changed color balance using xnview and resized it (x2).
I wish I had a barlow x2 or x3 !
Let me know what you think about it...
Could you see the satellites ? I did all the luminosity / Contrast glitches on my notebook screen and someone told me that he could only see one satellite... So I'm suspecting a big difference between my screen and "regular ones"... I've joined a frame of the video for you to see the original before processing... All the best, Xavier Mike here: I see three satellites on my Mac monitor. |

I had a nice calm night here tonight with great seeing, so I thought I'd run a few more pics of Jupiter and Saturn with my ETX90/QC combo. Not quite as dramatic as my December Pics, but very satisfying nonetheless...some interesting cloud patterns on Jupiter. I chose the best 80 or so out of about 200 pics, ran them through astrostack at 4x resampling at 448 width and used sharpening and deconving and a touch of Photoshop brightness and contrast adjusting.
I've included a picture of my setup, as I've been getting e-mails from some great folks requesting info so I thought I'd publish it here. Thanks for you're great site! Rick Krejci |

Great site! I got my scope (ETX-90/EC) a week ago and have since tried to use it in combination with a Canon S-10 digital camera. Here a the first results. The photos were taken using the standard 26mm eyepiece and 2x Barlow and exposure times were 1/30 and 1/15s. Since these are first results, from a very poor observation point (Rotterdam, Netherlands) and with an unstable platform, I guess a substantial improvement is possible. Keep your site going. thanks, Hero Boonstra Rotterdam, the Netherlands |

I noticed that venus isn't getting much coverage. Video and Astrostack can
really help get rid of the bright glare and atmospheric turbulence. Here
are three shots of Venus, Jupiter and Saturn obtained on 1/19/01, 1/2/01
and 1/12/01 respectively. All images were collected using a Lanthanum zoom
eyepiece at about 20 mm setting and the ETX 125 EC on the advanced field
tripod (#887). Eyepiece (infinity to infinity) projection was carried out
using a JVC 805 digital camcorder at 10X optical zoom mounted on a tripod
adjacent to the ETX-125EC. Images were captured either with the digital
still camera at 1/500 of a sec (21 frames; venus), or the video camera (88
frames, 1/250 of a second-Jupiter; 38 frames, 1/60 of a second for Saturn).
Astrostack was used to average the images with one iteration of
deconvolution. Using this method, I am able to capture the planets and get
them on the screen in about 10 minutes.
Thanks again for a great site. John |

Your site is the best.
I'm a real newbie. This is my third picture of Jupiter, taken with the Quick-Cam/ETX90 and processed with Astrostack (whose author deserves endless kudos). I sent it to a friend of mine who asked me about the red dot on it, which I thought was artifact. It is, he pointed out, the transit of Io across the surface, occurring at 7:30 pm central time.on 1/23/01. Blew me away.
I appreciate all the website activity of those people I have emulated. I'm having more fun than any human deserves.

I'd like to thank you for the most informative ETX/astro
photography site on the web. Well done!!!
These two photo's were taken with an ETX 125 and a doctored Quickcam
Express.
This camera only supports 320x204 resolution. Could someone tell me
whether it's worth changing it for one that supports 640x480, in order
to get a little more detail in future?
If you think their good enough could you show them on your Guest Astro
photography Gallery with my question?

I'm from Portugal and my age is 18.Ive been taking
photos over the moon, planets and deepsky since i own
my etx-125ec which i would like to show you (and if
possible be shown on you wonderful site). As i havent
much experience with long exposure photos you may find
the deepsky ones a little poor.

Thanks to your terrific site and the useful information it provides, I
was able to solve a number of minor problems interfering with the
operation of my ETX-90EC. The attached photo through the ETX is a
composite of the moon, photographed with a hand-held Olympus D-460
digital camera, Jupiter, and Saturn, recorded with a hand-held VHS
analog camera, and digitally processed on my computer.--Alan Bodnar
