First Light Celestron CGX 1100 Edge HD

Image
June 24, 2020: Today I was able to pick up the new Celestron CGX 1100 Edge HD. At home I immediately installed and adjusted the polar finder. Then I mounted the optics and balanced the whole thing. Then the finderscope is adjusted to the main optics. Unfortunately I didn't have the right screws to mount the StarSense. Either they were too long or too short ... When it was finally dark I had to do a manual alignment. First I aligned the polar finder as precisely as possible to the north and then carried out a 2-star alignment. For some reason, the finderscope was no longer properly aligned with the main optics. That made it very difficult to find the star with the main optics. Therefore, the whole alignment took a long time. Besides, I probably hadn't done it well either. In any case, I positioned the scope on the M 27, but saw nothing in the image field. The plate solving with Voyager also broke off and could not determine the position. Then I tried it with the M 51, which was ...

ZWO ASI 6200 MC Pro First light

Image
Finally a clear night again. There were a few high clouds, but nevertheless I could finally try out the new ZWO ASI 6200 MC Pro on February 16. The clouds were noticeable in the photos, but the result was still promising. At least I could try out a few things and among other things initialize and activate the autofocus function in the Voyager. So from now on I can automatically refocus during longer image sequences. On February 17th it was clear and I had programmed the following objects to be photographed: - M 31 - Andromeda Galaxy - M 42 - Orion Nebula - M 45 - Pleiades - IC 434 - Horsehead Nebula The Andromeda galaxy soon disappeared behind the house, and so I could take only 10 pictures, which were not enough to make a good photo. Next I processed the Pleiades. From 48 pictures à 30s the following picture was created: M 45 - Pleiades: ZWO ASI 6200 MC Pro, C 11 EdgeHD, Hyperstar V4.0 After that I started with the Orion Nebula. From 138 images à 30s the following image was created: M...

Orion Nebula 2nd try

Image
On February 15th, I made another attempt. Since I always had problems with the fogging of the optics and the newly ordered heating has brought no improvement (apparently it is defective) I have warmed the front plate with the hair dryer so that it does not mist. I took a few pictures with the Celestron NexImage 10 from Mars. Then I photographed with the EOS behind the eyepiece the moon and then the Orion Nebula. The moon still had a blue fringe of color and the Orion Nebula showed a true color spectrum in the stars. I suspect that this comes from the eyepiece and will therefore make the next attempts without an eyepiece and connect the camera directly to the telescope. Moon with ISO 200 1/60s: I made several images of the Orion Nebula. First an image with 3 minutes exposure time at ISO 200: You can already see the red color of the Nebula. Another image with 2 minutes exposure time at ISO 200: Also here the red color of the Nebula is already visible. An ima...
