First night out for a while with the AZ-GTi...

[fwm891]

Treated myself to a new Celestron  battery pack to replace my old motorcycle lead acid battery which has really had it's day. Set-up went as normal so no problems with the battery and I just left it chugging away while I went and did the washing up! (one has to be practical to get brownie points).

Scope used was an Altair 80mm triplet with 0.8x reducer fitted and an ASI 585 uncooled camera. The AZ-GTi was controlled via an ASIAIR Plus. No filter other than a UV/IR cut filter (Baader) the moon had risen but still quite low and was about ¾ illuminated. I used 30s live view stacking via the ASIAIR Plus.

I used GraXpert to remove the moon gradient and PI to stack and the remaining processing.

Main stars have blown out but it's the surrounding nebulosity of M45 that's the main feature.

Hope you like.

Very nice Francis! Do you use a EQ wedge or just use it in alt/az mode?

@DrStrange Thank you. A wedge. Necessary to get the length of sub frames.
