First light with QHY8L

Well after get my new qhy8l back in feb. I finally got out to try it out.

After wasting the whole night triing to get a good polar alignment I gave up and went with what I had and just guide out any errors. Well that was the plan. PHD wouldn't play and I couldn't get it to calibrate. No movement in the star!
So in the end just point the scope at M8 and took a series of sub.(thks Alistair)

27 x 1 min &
4 x 5 min subs.
+ 31 x bias,
27 x 1 min darks &
4 x 5 min darks.

After working out howto debayer in maxim and and getting the right offsets. Which I couldn't find much info on the x,y offsets. I settled on x=0,y=1.

Also attached is a 1 min and a 5 min sub. and a blue rendishion that I was working with till I found an image to compare it to and realised the debayering wasn't right.

I was surprised by the differance in the 2 subs. Didn't expect birds in the 5min sub, I just thought the trailing would be longer.

When I was packing up the next day I Noticed I hadn't attached the cam square to the focuser. .

So to sum up. very happy with the cam and the result. Just have to get PA sorted. (cant wait to get obs finished) and work out what happened to my guiding. Using maxim DL to capture and process and find it pretty good to use.

Just need some warmer nights, (dont like the cold) and some clear skies.

Cheers
