This was my first long exposure attempt at any object. I must be doing something wrong because, there is just not a lot of depth for 17 hours of exposure. It's from my backyard redzone, so not a dark site but I used my L-Enhance filter to try and compensate for the LP. I was still on a gain zero kick with my camera which I am now confirming is too low. Oh welll...lesson learned.
This is 17 hours of 3 minute subs. AT115EDT refractor with At 0.8X reducer and L-Enhance filter. Gain zero, 0deg. C cooling.
