Thought I'd send you my 1st attempt at photographing the sun. Bought a scopetronix solar filter off ebay a couple of weeks ago this is the 1st time it's been clear enough at the weekend to get the ETX out and take some pics only got about 1/2 an hour outside before the shower clouds rolled in. Hopefully you'll find the pic worthy of a place in your guest astrophotography section, details as below. Telescope ETX 105 very roughly polar aligned (hard to find polaris in the daytime!!!) tracking with the standard hand controller Scopetronix solar filter Meade 40mm Eyepiece Camera Nikon Coolpix 4500 attached to the eyepiece with a Scopetronix digi-t adapter Approximately 2x optical zoom ISO 100 6 shots taken at 1/30th second exposure F3 Image resolution 1024x768 Processing Aligned and stacked and processed the 6 images in Registax and cropped the area with the sunspot on it to keep the file size down for emailing. I did try some more shots with a higher power eyepiece but couldn't seem to get them in focus. Will hopefully have another go tomorrow, weather permitting.

The attached image is from August 18, 2004, as the sun set near Keene, Ontario. At this time Sunspot#652 was located near the centre of the solar disk. As the clouds rolled in front of the sun, it looked more like a very bright Jupiter than it did our closest star. I used a Nikon Coolpix 995 camera with a 2X teleconverter to take it.

Well, with the big one gone (652), this much smaller group still holds a few surprises. ETX-90RA, Toucam Pro webcam, F30, 180 stacked frames.

Thought you might like to put this ETX 105 sunspot photo in your gallery. It was taken at prime focus using a Meade LPI imager. I've sharpened it a little and cropped a bit to give a smaller file size.

The weather is finally starting to improve today so I thought I would dust off the old ETX 60 and check out the sun. Much to my surprise there was a huge sun spot. The SOHO web site identified it as Active Region 652 and it is the largest active region since October 2003. Grabbed my camera and tried to take a photo to send you. Here are the stats... Scope used was Meade ETX 60 AT (fake alignment but it tracked well enough), Celestron full aperture mylar solar filter, Orion 7mm to 21 mm zoom set at 15mm, Parks #11 filter, ScopeTronix Digi-T ring & 28mm-T step ring, Nikon Coolpix 4500, Nikon MC-EU1 electronic cable release, zoom 50%, exposure was 1/250 sec at f 3.6, ISO 100, flipped horizontally in Adobe Photoshop and focused just a little with unsharpen mask. No other processing. Photo taken on July 22, 2004 from San Diego, California.

Attached is sunspot 652 captured yesterday with my ETX-90RA @ F20, Baader solar film filter, and Vesta Pro webcam. Seeing was average. 186 of 900 of the best frames were stacked in Registax, processed in Picture Window Pro.
You're going to get tired of my submissions, but I thought I would share sunspot 652 once again, this time in blue light and at high resolution. Details are on the picture.

After the meagre sunspots observed at the time of the recent Transit of Venus, I was much suprised this afternoon to see four large spots each associated with several minor ones. I managed to get a shot of three of the larger spots before the clouds came over. I've done a little experimenal enhancement and I attach the original and enhanced photo for your gallery.

The weather here is not very good for night observation then I decide to dedicate some time for experiments with Sun light. Here I am attaching a clolour and black/white Sun spectrum images and spectrograph with wavelenght and some elements determination. For this experimet I have used ETX90EC and TouCam (Registax, Adobe Photoshop and Visual Spec programs for images processing and spectrum callibration respectively). The images were obtained in following meaner: just before CCD chip I have placed a diffraction grid (100 lines/mm) and I have recorded a small *.avi file (25 frames) of Sun spectrum proceeded from some sun reflex of TV antena (on the nighbord roof). I think this is the first approximation to get the spectrum of bright stars. I will inform you if it could be possible, but I hope yes. I hope you can put this first results of spectroscopy of our star in The Sun Gallery.

Could you post in your Sun Gallery. Thank you !

I'm sending an imago of the reflected solar spectrum in a window, its made with the TouCam, the Etx-90 and a Diffrection Light net->(its no easy to find) in the camera adapter, I think that its very interesting to find the lines, in my image you can see the lines of the Sodium, Hydrogen and Calcium and other lines in the blue.

Here's a view of the Sun taken on Sunday morning, April 18,2004. I used a Meade etx125, an Orion solar filter, a Nikon Coolpix 4300 digital camera, a 40mm Scopetronix plossl, and Digi-T adapters. It was taken at a 1/500th of a sec at f/2.8. using a Nikon electronic cable release. Some small sunspot groups are visible, nothing major....just testing out some new equipment!!
