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

Dean Glace
 

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 and Happy New Year:

My first image of 2020 is a small reflection nebula, vdB42, which lives just west of its big brother M42:

Hi,

Last night was a reasonably good imaging night.  I re-shot the Medusa
Nebula.  Results much better than my 2013 shot...

First shot I've taken since 28 October when weather and electricity went
weird...  :-)

Thanks,

NGC 1807 & 1817

Gregg Ruppel
 

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

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 totally agree, my images are for demonstration purposes only and not a scientific collection of data.  And thanks for sending that AAVSO link – the light curve is DRAMATIC!

Brian,

 

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.

LBN 917 is an HII (according to Simbad - http://simbad.u-strasbg.fr/simbad/sim-id?Ident=LBN+203.50-30.15&NbIdent=1) about four degrees away from the popular IC 2118 (witch head nebula) in Eridanus. Several denser areas can also be found in the Planck Galactic Cold Clump (PGCC) catalog. I have a feeling that the combination of the IFN and HII could have led to the somewhat odd colors.

Grus Triplet

Bernard Miller
 

Hi,

This is an image of Grus Triplet. This group of galaxies is about 60 million light years away in the constellation Grus and is comprised of NGC 7582, NGC 7590, and NGC 7599. These three galaxies along with NGC 7552 make up the Grus Quartet, which is part of the IC 1459 Group. This image contains data taken from a CDK17 and RCOS 12.5 and represents over 57 hours of total exposure. You can mouse over the image to see an annotated version that shows just how many galaxies are in this image. I also posted a cropped version that shows more details in the triplet.

Comments and suggestions welcomed.
