Re: Autoguider decision

Looking at various zwo cameras for autoguider and maybe imaging. To autoguide 152mm F8 - 1200mm. Could use 65mm by 400mm guide scope I have. So choices; 120mm , cheap on sale $200; maybe not so sensitive enough or wide enough? 290mm mini, $300, 2.0, effectively guides scope only which is primary mi...

Re: Diffraction patterns 1600mmpro + ZWOEFW +RGB filters

Hi there my filters are on the proper side of course. The 36mm EFW do not have any holders or fixtures, you just drop the bare filter into the nest and attach by screws with washers. If you look around this forum you'll find out the issue is much more common and some people already sold their camer...

Re: dealing with reflections and diffraction with ASI1600MM

Does this occur more with refractors/reflectors? With or without focal reducer? I have a Stellarvue 102mm triplet with FPL-53 glass. These reflections seem worrisome and I have not made the ASI1600 purchase yet. This is likely due to the sensor not being AR coated. The new ASI183MM Pro uses the ICX...

Re: ASI120MM-S

that's flash of the light Which "flash"? What light" Can you elaborate? I am talking about MULTIPLE horizontal lines, old TV style... The lights you can see in the room. They are likely introducing cycle noise to the image. Point the camera away from them. Also, dont point it at that laptop either.

Re: Diffraction patterns 1600mmpro + ZWOEFW +RGB filters

Jumping in here... The first image in the thread shows diffraction caused by the Panasonic sensor in the camera. This is not a ZWO specific issue. Any Astro camera that uses this Panasonic sensor has this problem. It only occurs on really bright stars, and the coating Sam is referring to is Anti Ref...

Re: PHD2 does not find my ASI174MM Mini

After a day and a night of research, I figured out that I can connect PHD2 to my ASI174 when I use the WDM option in PHD2. This was mentioned in an old thread somewhere referring to older versions of PHD2. So it just didn't occur to me that the same issue might be back with version 2.6.3. Apparentl...

Re: OIII Narrowband Flats Issue - ASI1600MM-C

seems like you should see if it calibrates out before raising the flag higher. It is concerning, there does seem to be some unusual interference. if it all cancels out in the end, then maybe no harm no foul? B I am waiting on the weather to test that, but the likelihood of this processing out of th...

Re: ASI 1600 MM- Cool and Coma Corrector

The filter wheel adds 20mm. If you obtained the ZWO OAG (16.5mm) and used the 11mm spacer that came with the camera, and the 1mm T2-T2 adapter that came with the wheel, you would be at 55mm.
