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.

c2017 T2 PanSTARRS

Hi all:

Comet T2 PanSTARRS continues to shine around magnitude 9 as it heads toward a meeting with the Double Cluster later this month:

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).

Anyone going to be at DSNM from 25-29 of Feb 2020?

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.

NGC 1807 & 1817

Hi all:

NGC 1807 and 1817 are two open clusters in Taurus:

http://www.greggsastronomy.com/IMAGES/ngc1807_1817-LRGB.jpg

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.

Astronomy Mag - Feb 2020 - Bernard's NGC5128

Howard Anderson
 

Hi Bernard,

Congratulations on your NGC5128 image in Feb 2020 issue
of Astronomy magazine, page 70.  Great detail in that shot.
Wish they would have printed a larger image but it is really nice!
They printed it big enough to tell that the original has superb
detail as usual for shots you've taken...

Looks like clouds have briefly departed and humidity is reasonable
so tonight I set up the first shot I've tried to do in months... Now,
it would be nicer if the moon wasn't a factor tonight but other conditions
are way better than they have been for months....  :-)

Thanks,

Howard

Arp 287

Dan Crowson
 

Arp 287 consists of NGC 2735 (UGC 4744, PGC 25399, VV 40a and others) the spiral at the center interacting with NGC 2735A (MCG+04-22-003, PGC 25402, VV 40b and others) just to the left (east) of center. Part of Arp’s Double Galaxies – Wind Effects, these are located approximately 178 million (http://simbad.u-strasbg.fr/simbad/sim-ref?bibcode=2016AJ....152...50T) light-years away in Cancer.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

420 minutes total exposure – 7 hours

 

Imaged March 5th, 2018, December 31st, 2019 and January 4th, 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.

I posted the below elsewhere. Images like yours are rough at best because humidity or seeing could yield the visible differences shown…

 

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. It looks like it has dimmed almost a magnitude since the start of November.

Here’s a side-by-side comparison: 2016 to last night.  The old shot was shorter exposure so I equalized exposure in Photoshop.  You can see that the field stars are identical in appearance.

 

A supernova would be the biggest event of our lifetimes.  Stay tuned.
