Hickson Compact Group 2 consists of:

 

UGC 312 (UGC 312 E, PGC 1921, HCG 2a and others) – the odd spiral left (east) of center

Mrk 552 (UGC 312 W, PGC 1914, HCG 2b and others) – the spiral to the right (west) of UGC 312

UGC 314 (PGC 1927, HCG 2c and others) – the spiral below UGC 312

UGC 315 (PGC 1934, HCG 2d and others) – the spiral to the left of UGC 314

 

All of these are located in Pisces.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged December 20th, 21st and 27th, 2019 and January 13th, 20202nd, 20th and 29th, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

[Edited Message Follows]

We are finally operational. It should have happened it October but numerous things kept getting in the way. We still have a few things that need to be done like our low-light (non-IR) monitoring IP camera install but the system is at least operational as of last night.  Hope to have an actual image soon, weather permitting.  Here is a (not great) photo of our relatively modest system.

Re: Finally operational

There is no OAG on the piggyback system since it is a 200mm Canon camera lens so there would not be enough back-focus. There is a mini-guidescope/guide camera (can't see it on the image as it is on the other side) but our tests have shown that with our polar alignment and pro-track we can do 15 minutes unguided so we will not be using the glidescope much. Camera (QSI 690) and lens are Tom's but I built the system.  Better benchtop build photo is here, you can see the rings for the mini-guidescope:

Congrats on getting all set up.  Is there an OAG in there somewhere or is the piggy-backed system also a guider?

M105

Dan Crowson
 

M105 (NGC 3379, UGC 5902 and others) is large elliptical at the right. The most recent (http://simbad.u-strasbg.fr/simbad/sim-ref?bibcode=2016AJ....152...50T) reference puts this one at approximately 36.6 million light-years away in Leo.

 

NGC 3384 (NGC 3371?, UGC 5911 and others) the odd-looking spiral at the center. This one is approximately 32.7 million light-years away.

 

NGC 3389 (NGC 3373?, UGC 5914 and others) is the blue spiral at the left. This one is approximately 66.6 million light-years away.

 

All of these are part of the M96 or Leo I group of galaxies. While the members list appears to be vague, a table of some of them can be found here - https://en.wikipedia.org/wiki/M96_Group.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 12x300s – 60 minutes each – binned 2x2

 

420 minutes total exposure – 7 hours

 

Imaged December 29th, 2019 and January 3rd, 5th and 6th, 2020 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

 

LRGB - https://www.flickr.com/photos/dcrowson/49368733418/sizes/l/

 

This image was taken under extreme conditions. January 3rd was very good. I managed to capture asteroids down to magnitude 20. The RGB captured on January 5th and 6th was during terrible conditions but good enough for LRGB.

Re: Animas in the News

Brian,

 

That might not mean much since the moon is near full. I didn’t check to see if there were camera observations but I suspect they would be a little challenging. Maybe in another week without the moon?

Yes, I’ve been plotting AAVSO light curves for several days since you alerted me.  Going back 40 years it is UNPRECEDENTED.  But the last few days show nothing changing.

Brian,

 

Sadly, my stars can look this different in successive exposures with the recent seeing. :/

 

I posted this locally because several people asked –

 

Go to https://www.aavso.org/ and enter alf Ori into the search box on the right and hit plot light curve. It might sound bad for lack of a better term but I would then uncheck the visual observations box on the chart. You can change dates among other things by clicking the preferences button at the top. It looks like it has dimmed almost a magnitude since the start of November.

 

There is something here in that it appears to be the dimmest it has been in a long time. I changed the chart to go back 20 years and it doesn’t show anything like this. Being a bright star, it can be a challenge to get non-visual observations so something could have been missed.

 

It is not a bad thing that people are asking questions and looking. If I see another Orion image minus Betelgeuse I might scream.

Spaceweather picked up my side-by-side Betelgeuse shot.  Two caveats for you experts:

  1. Dan pointed out that this is really not a scientific comparison of brightness due to many factors (humidity, elevation, transparency, etc).
  2. The last 7 days have shown that the dimming has ceased (lightcurve is flat).

I am going to DSNM on the 25th of Feb to work on my telescope. If anyone is going to be there when Imam there, I would like to have some help with some control software and collimation of my scope.

Hi all:

NGC 1807 and 1817 are two open clusters in Taurus:

NGC 1807 is the cluster on the right (about 20 stars); NGC 1817 is the larger cluster on the left (about 60 stars).  The faint fuzzy behind NGC 1807 is the 14.9 galaxy PGC 16865.  There is a low surface brightness galaxy a few arcminutes to the west.
