Hi;
I wonder if someone can extend some help; I cannot figure it out what I'm doing wrong. Its the first time I do this...
I have as Orion 8" Astrograph with a ASI294MM camera & 60mm F4 finder scope with an SV305
I picked the this scope based on many beautiful images seen here!!!
I attempted to just capture the MOON! and I cannot get it to focus???
The best I can do is the image below; I know I should be able to, as the Guide scope with svbony ccd(SV305) should work; The moon (out of focus) will grow in image size when going the wrong way with the focus, and so when I go the correct way and it gets smaller, I expected to see a clear image at one point, but after a while getting smaller (focusing in the correct way) then starts to grow again. I cannot seem to focus it at all; so frustrating
I have seen galactic-hunters use the 8" F3.9 orion astrograph with ASI1600MM so I cannot understand why I cannot get the moon in focus; with my ASI192MM. Its way too bright... like I'm looking at the sun...
I presume it is with the Ekos settings; I made the gain very low (1%, 10%) and the exposure time 0.1s to 0.01; and its always way to bright??? why??? froze my butt at -10C tonight...
Any help would be great! I'm using a raspberry astroberry unit.

Hi JR, The moon, especially full, can be tricky. I recommend focusing on a bright star before slewing to the moon. If you can properly focus on the stars then you’ll know that your backfocus isn’t causing any issue. But from what you describe (moon getting smaller then larger again), you are indeed overexposed. Start with the shortest possible exposure time your camera will allow. The Orion 8” Astrograph is a FAST scope at f/3.9 so it captures a ton of light! You might need to do even shorter than 0.01.
