Description

So last night was an interesting night! Everything went well until I woke up at 2am and found that at 1am I lost power (tripped breaker) however I managed to get back on track and obtain 4.5hr of data.

Although I was only meant to do luminance I did slip in some Ha & RGB.

My luminance data seemed to have alot of gradient not sure why , think it may be my LED lamppost directly outside my garden. I'm still waiting for my adaptor for IDAS D2 filter.

152x60sec Luminance
28x60sec Red
26x60sec Green
29x60sec Blue
10x180sec Ha

I have another two clear nights ahead of me , so not sure whether to increase my data on M31 or choose another target.
