M106- it is an intermediate spiral galaxy in the constellation Canes Venatici. I took about 12h of data between Hydrogen and LGBR filters, however I ended up throwing all of the L data out as the filter was not exactly clean and I didn't have any flats for it.
To continue the Galaxy parade, M106, super rewarding target, I will revisit it for sure with the mono camera at some point just to get the structures pop, there's so much going on! 5 hours here, clouds are in, later on followed by full moon leaving no chance to gather more exposures.
Auroras blasting away, not too far from Copenhagen right now
Excuse me, if other people can go on a Holiday with their golf bags, skis and bycicles, what's there to stop me traveling to Gran Canaria with my telescope to see how the night sky looks like 30° south from where I live? Nothing!
I even found the fuse box and killed all the lights after this picture was taken
Thor's Helmet, not too bad for a target that doesn't rise more than 20° above the horizon at my location. Luckily it's quite bright as far as deep sky objects go. About 3.5h integration time
Quick pick of the Moon
IC 443 - Jellyfish Nebula, captured over last couple of nights. I opted to make a false color image using a S-H-H palette. Just over 10 hours of integration time.
Very strong auroras tonight, clearly visible with naked eye, close to Riga, Latvia

Jupiter with it's moon Ganymede last night
I've had about 5 hours of clear sky since end of November. Yesterday, like some sort of a Christmas miracle, it cleared up for 3 hours and I jumped into action. Heart Nebula. Merry Christmas everyone!
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun. (Wiki)
Last of my November yield,
7h total time,
2h S
1h H
4h O, all 5 mins
The California Nebula (Also known NGC 1499 or Sh2-220) , once again, shot over 3 nights in mid November, in SHO palette, total integration of about 9 hours, with more than 50% of that time spent on Oxygen filter

The Lion Nebula, Sh2-132, photographed over 3 nights in mid-November using Hydrogen, Sulfur and Oxygen filters although I only ended up using H and O shots for the Nebula.
While I was waiting for Jupiter to come up, I decided to photograph 2 very small nebulae while I have my powermate attached. I guess normally you wouldn't do that as it dims the telescope, but since these are quite bright, they worked out kinda ok-ish.
Owl Nebula and Blue Snowball Nebula
I know Jupiter is not in opposition just yet, but who knows If I will have clear skies when it is, so have to grab an opportunity when I can.
Jupiter with it's moon Io on the night of the 15th of November.
Taken with Celestron 9.25 Edge HD and 2x Televue Powermate
M82 or the Cigar galaxy shot a month ago, 37 x 3 minute shots with UV filter and another 27 with optolong l-Enhance
Skies cleared up last night for the first time in weeks so expect more astro pics in next couple of days :)
Ghost Of Cassiopeiae, Sh 2-185..
really wanted to have it finished by Halloween because of the "Ghost" theme, but just couldn't make any sense of the data that I gathered (11h of 3 to 5 min exp) (L,G,B,R,H,S,O)
.. so basically what I did.. Lum layer - stars reduced, RGB - keep stars only, .. once again, recombine RGB, this time replacing R with H, because R has a weak signal.. combine reduced star L with freshly acquired HGB . Move on to narrow band data - strong signal with H and S, none in O.. . for narrow band RGB channel combination HSO pallet chosen.. last step, pixel math roughly going 0.5:0:5 RGB + HSO.. This is not a recommendation, these are just notes for myself
