Description

So, this is the product of my first light with my William Optics ZenithStar 71 APO Doublet from Tues night (I didn't get this done till today due to work yesterday, etc).

William Optics ZenithStar 71mm APO Doublet (418mm)

Sony a6000 camera

Celestron AVX mount

Unguided, but tracked (part of my guidance came in...unfortunately, it's not the camera part...it'll be here next week)

45 x 30 sec exposures, ISO 640

I think that this scope takes very nice, crisp images. The only issue I have with it is that there's some chromatic aberration around the bright stars that I haven't been able to solve with either PixInsight or Photoshop. I'm not sure if it was my exposure, my ISO, or what. the actual focus was dead on, and I can provide the Bahtinov mask image to prove it!

Anyone have any suggestions? Thoughts? Comments?
