Alpha Centauri Binary System Single 0.6 second exposure, no tracking, with Vivicam 3930, 6x zoom through 26mm eyepiece on ETX90-EC. Image rotated and flipped for orientation. No other post processing. This famous pair at 4.4 light years are in a 79.9 year eccentric orbit. They are currently separated by 10.6 arc seconds and headed for their minimum separation 4.01 arc seconds in 2016. They were last widest apart in 1981 at 21.7 arc seconds.

I attach a photo of M42 taken using my ETX105 and Canon EOS300D. It was taken while on holiday in Cyprus on September 1, 2004. This is my first attempt at deep sky astrophotography, as well as mounting the scope in polar mode. I am still having some problems with alignment that is accurate enough for a long term exposure. The attached photo has been processed heavily using Focus Magic motion blur removal. Best Regards, and thanks for a great site.

Here a deepsky object quite difficult one for the ETX90. The mag 11.5 beautiful spiral galaxy NGC7479. Job Geheniau The Netherlands

This is my first DSO astrophoto. It only takes 1min 30sec in AltAz setup, but I spent more than half an hour to edit it so that the invisible light can pop out. haha..... "I am not the expert in using Photoshop :)" After done a major tuning on both axis on my little ETX, I found out that the slippage and backslash problem on both axis are gone. :) Hope you like this first try out.

Quite nice deep sky exposure of 40 million light years away Messier 102.
And a beautiful globular cluster, Messier 15.
Messier 39, open cluster.

Despite the bad conditions yesterday I tried the Cocoon Nebula. I think here I am on the edge of the ETX90. I made more than 300 exposures of 30 seconds and used 112 of them (thats more than I ever did)! And even after that the Nebula was difficult to see after stacking. It is a typical H-alpha object I guess (because the books sy magnitude 7.2....normally that must be no problem) and I can't use h-alpha filters on the ETX. They take away too much light. Now it's time for a bigger aperture :-)

On 31 july 2004 there was a quite bright supernova. I waited some weeks for better weather but nope. So here my first and not the best picture of a supernova with an ETX90. Bad conditions and my ETX was bad aligned, so I only managed to get 6 (!) of 210 pictures of 35 seconds from the supernova just down in the picture (on the right a good one from another kind of telescope). Can do better but the weather here is not good. Just to show you that Supernova are possible with an ETX. This one (SN2004dj) was magnitude 11.6
Here is a better one. Made this one last night. My first supernova with an ETX90.

Long time no see. Here in Europe is for MONTHS bad weather and too long light. This night was beautiful for the first time. Tomorrow I will be on vacation in Greece and I bring my ETX90 along to shoot M16, M17, M20 and maybe Pluto. So just before departure here M27 I did last night (from 11:30 pm to 3:00 am) with my ETX for your deepsky gallery. See you later. Job Geheniau, The Netherlands

Attached is an image of the Triffid imaged with a ETX 70 AT. 50 images at 10 secs each, best 12 stacked.Atik 1 c webcam.(modified for long exposure Phillips Tou cam)-stndard out of the box ETX 70 AT, alt azimuth mounted. Needed to do a truckload of processing in Photoshop and then used NEAT to remove noise-started with what looked like a black rectangle with a few dots but the digital information was there and needed to be coaxed out.
