That's a great selection, Roel. I'm particularly looking forward to trying the twin quasar in Ursa Major.

[nother]

Very nice collection and a good starting point for testing my new scope ... I just have to blow away those bloody clouds

[MartinMeredith]

Great selection Roel. Arp 145 is one of my absolute favourites and worth spending time on to pull out the ring -- fascinating object to read about too.

[Cey42]

Great selection! Lots of my favorites.

I'm getting very consistent results from my setup now and am trying to do better with Sharpcap.  Tonight is the last clear night before Snowpocalypse II, so I wanted to hit some targets.

Great list! I picked up a few of them last night through my AT66ED using the SVBONY 305 Camera.  Live stacked using SharpCap Pro. I was guiding with a Orion StarShoot Autoguider but my exposures are short (15 seconds) so I don't think that was really necessary.

 

NGC 40 - The Bow Tie - Live stack 40 x 15 seconds @ 400 gain 

 

NGC 1501 - Live stack 40 x 15 seconds @ 400 gain

More from my EAA observing session last night can be found here - EAA - 02/01/2022.

 

Hope to pick up a few more from this list tonight.

I really like this challenge list! Looking forward to  trying many of the ones I have not shot before. These images taken with C8 Edge/ .7 FR/ Asi294MC/ Bin 2/ AVX mount/ PHD 2 guiding.

I got out to see NGC 1514 on February 3.   I'm still having trouble with high haze hurting transparency that has been persistent over the last few weeks.    It is was also cold at 5F that is my lower limit.    Naked eye limiting magnitude under m4.   NGC 1514 was not eyepiece visible.

 

I had my Astro-Tech 102 EDL with a ZWO ASI-294mc out.    CG-5 ASGT mount unguided.   SharpCap live stacked and saved as viewed.   510 second total exposure (34x15s).  File size reduced.   

 

NGC 1514 1.5 x 1 degree.   North up, east left.

Had a nice clear night last night.  A little cool and a little breezy, but nice clear skies.  Was able to snag a few more from the challenge list.

 

All of these were observed through my AT66ED using my SV305 camera and live stacked with SharpCap Pro.

 

IC 405 - Live stack 120x15 seconds at 450 gain.

I could just start to see the nebula at about 6 or 7 minutes into the live stack. 

 

HCG10 - Live stack 60 x 30 seconds at 450 gain.

I was able to resolve NGC 542, NGC 531, NGC 536, and NGC 529.

 

NGC 2336 - Live stack 60 x 30 seconds at 450 gain.

 

NGC 2841 - Live stack 60 x 30 seconds at 450 gain.

Really liked looking at this one.

 

UGC 3697 - Live stack 60 x 30 seconds at 450 gain.

The wind gusted up a bit during this live stack and you can see that in some of the star trails on the brighter stars but UGC 3697 still resolved nice in the center.

A fun night last night. Seeing average but I managed to get some more of this month's challenge objects. All images taken with C8 Edge/ .7 FR/ Asi294MC/ Bin 2/ AVX mount/ Sharpcap 4.0 Pro/  PHD 2. All have been cropped.

Twin quasar - this was a real challenge but so happy I found it!

Another mediocre night but still very fun! I managed to get a few of this month's objects despite poor seeing, poor tracking and messed up flats (first time trying flats with big dob).

I took a lazy dip into Roel's excellent list of targets this month and picked just one easy (M81) and the challenging (Twin Quasar) target. It's my first look at M81 this season, and my first time capturing the twin quasar. (Both captures taken with my 130EDT triplet, reduced to f/5.5, ASI290MM mini at 300 gain, no filters and no binning, using ASILive; north is up in each image):

 

M81; 20 x 15 sec

 

 

 

What makes this capture of M81 interesting to me, is that I can see the very faint irregular dwarf galaxy companion Holmberg IX, well over to the left (east) of M81, and about 40% of the way up from the bottom (south) end of the frame. It  is just a very faint patch, barely visible in this 5 minute exposure, but I could spot it while live stacking after only a couple of minutes. For any other self-confessed fans of Holmberg IX, this is the first time I've spotted it in such a short exposure, and I was surprised as I'm only using a 130mm refractor. 

 

 

Next up is the twin quasar in Ursa Major, which also has the PGC designation PGC2518326.  This one popped up pretty quickly, and is easily visible smack in the middle of the frame in this 2 minute exposure. I've also included a cropped and zoomed view of both of the "twin" images. The angular separation of both components is about 6 arcecs; as an aide to finding this one, the galaxy NGC3079 is about 10 arcminutes to the south (just below/outside my FOV).

Out last evening and captured a couple really nice targets from this months challenge (thanks Roelb).

 

Same setup as the last couple months (my AT72EDII is really starting to get grumpy).  Celestron Super C8 Plus + ASI533MCP.  Most were 15s subs at gain 350, except the Clown Face which was 4 seconds at gain 125.

 

Bear Paw (NGC 2537, Arp 6)

 

Clown Face (NGC 2392)

 

IC 2233 | This one isn't on the list, but it was so close to the Bear Paw that I had to take a peek.  This is one of the thinnest galaxies known.

 

Integral Sign (UGC 3697)

 

M1

 

NGC 2336

 

NGC 2841

Got out the night of Feb 6th for a few hours before the clouds rolled in.  Had nice views of a bunch of planetary nebula. 

Photos unprocessed but cropped, taken with CPC-11 F/6.3 ASI 294MC Pro cooled, 18x20secs bin 2x2.

Relaxed viewing last night with the C6 Hyperstar.  Not ideal for most of these objects, but I tried some of the PNs anyway (not shown).

Had a clear night and wanted to test out the 290MM with the .8x reducer.  ZS73 at f/4.7 on my AZ-GTi in AZ mode with Astroberry/KStars and Sharpcap.  Everything saved as viewed.

 

I went after the Twin Quasar and captured something on the sensor, but it didn't resolve very well (it's there, though!).  I may try with longer exposure or higher gain since it would be neat to capture it.

I was out the night of Feb5/6th and was able to get quite a few of the targets.  It was a bit windy and my stars show it. 

 

Using my 80mm Triplet with QHY183C and a new to me IDAS LPS-D2 filter.  Riding the AZGTi as an EQ. 

 

Everything at Gain 25, exposures were between 4s and 30s

 

Easy:   I have looked at these recently so skipped them for this night.  Hope to come back and do better than I have so far.
