First night - missed the target and took lots of images of some nearby stars
Second night - 35 x 2 min
Third night - 60 x 2 min
I've tried stacking the two nights separately and all together to give a total of 3 hours, but the stacked images all turn out roughly same. Think I must be limited somewhere else and the extra data isn't being captured. The best of the batch was a very quick process of night 3, 2 hours. I was happy to see the bubble shape and a bit of cloudy bits 👍

Last summer Wim @wimvband I entertained ourselves with processing freely available data (subs) from the Liverpool Telescope, since Sweden is too light for AP that time of the year. I was just told that one of my attempts on the Bubble made today's APOD! Yes I know, the data is from The Liverpool Telescope, a 2 m RC scope on La Palma, so not collected with my own stuff, but I did the stacking (Nebulosity) and processing (PS).
Now I just have to come down to earth again...
@Stu, @GavStar and myself met up for a bit of club observing Thursday night… cloudy so good that we met down the pub. Someone (not sure who) pointed out it was clear, so we headed out to stand and chat under clouds with a chill breeze for more than 2hours waiting for the skies to comply with Sat24. Finally we spotted what looked like the edge of the clouds… the others got ready to polar align. OK observing under a near full moon is not ideal.. but it does help with setup and checking your charts!
So what to look for… using Gavins new “magic eyepiece” we headed straight for the Horsehead, just visible, the flame slightly more so above. We were using a TEC160 on a goto panther mount, with 55mm plossl and the TNVC adapter to the intensifier, using a 6nm hydrogen alpha filter to “help”. The gain control worked really well to tune the balance of brightness (and noise) vs detail. The “white phosphor” giving a very neutral and “natural” view.
Right, where next? Up to the jellyfish ic443, nice gentle curve easily visible, checked on the monkeyhead nearby. We then cruised down to the seagull which filled the view and then tried to ferret out the medusa Nebula… it evaded us this time. Swept over the the pacman, the heart and then the California nebula. The latter as two broad nebulous bands crossing the field of view. We need to try a smaller scope to give a bigger field of view for these really big nebulae.
Swapped in a longpass filter and checked on M35 which looked great, M3? and then M81/82, very clear dark lane in the latter.. Clouds finally made a return and we packed up the wrong side of 1am, feet nearly frozen solid. Seemed like many of the streetlights had turned off as well, which is interesting to note. Going to be fun to poke this setup at nebulae when the skies are a little bit more conducive to observing.
