Brian,

 

Thanks for looking. I’m in it for the long haul and when you’ve imaged as many things as I have, that is what it takes. I still just keep a text list what I’ve imaged and what I need to complete things. Sadly, the data directory goes back to 2017 at this point for some objects.

Very nice, Dan.  Total props for persevering through 5 nights!   Holy cow, I lack that discipline.

NGC 5248 (UGC 8616, PGC 48130, Caldwell 45 and others) is a spiral galaxy located approximately 44 million (https://iopscience.iop.org/article/10.3847/0004-6256/152/2/50/pdf) light-years away in Boötes.

 

MCG+02-35-014 (PGC 48114 and others) is the Seyfert 2 ring galaxy at the top center.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10x300s – 50 minutes each – binned 2x2

 

390 minutes total exposure – 6 hours 30 minutes

 

Imaged February 25th and 26th and March 19th, 23rd and 27th, 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.

Hi everyone:

Comet c2017 T2 PanSTARRS appears to be trying to out do Comet Y4 Atlas as they approach each other near the NCP:

http://www.greggsastronomy.com/IMAGES/c2017-T2-PanSTARRS-LRGB_032820.jpg

I was only able to grab about 32 minutes of LRGB data before the comet dropped below the roof line of our observatory on 3/28. The small reflection nebula near the lower right corner is vdB 8.

Arp 283 consists of NGC 2798 (UGC 4905, VV 50a and others) on the right and NGC 2799 (UGC 4909, VV 50b and others) on the left. Part of Arp’s ‘Double Galaxies – Infall and Attraction’ class, both are located around 84-86 million light-years away in Lynx.

 

UGC 4904 is the somewhat odd galaxy located below Arp 283.

Hi,

This is an image of NGC 3324, also known as the Gabriela Mistral Nebula due to its resemblance of the Chilean poet (I have to admit, I’m not seeing it). NGC 3324 is actually the open cluster outside the FOV of this image. The nebula is actually IC 2599. The two are close together and often confused as a single object. It is about 7,500 light years away in the constellation Carina.

Comments and suggestions welcomed.

Hi all:
NGC 3718 is a warped spiral galaxy in Ursa Major, considered to be interacting with NGC3729 (left in the image).  It is also cataloged as Arp 214:
http://www.greggsastronomy.com/IMAGES/ngc3718-LRGB.jpg

Just below (south) is the Hickson 56 galaxy chain consisting of 5 galaxies.  Four of the five (excluding PGC 35631 on the left) make up  Arp 322.

I just have to say it is great to be able to pursue a hobby while staying at home for this miserable pandemic. Not everyone is that lucky. Thanks to Al and the rest for making this work. I am delighted to be able to continue to pursue my hobby thru this period. It makes life much less boring and stressful.

In my case, it is even better since I live at a dark sky site that is clear in summer. I am working on a new equipment configuration for at home. Fortunately I am able to order things like aluminum on line and even disinfect them when they arrive if I wish. We are in rural hibernation and anyone that arrives is  sprayed with bleach. They hate that. <G>
