Re: Arp 213

Eric and Josephine Africa <eja24601@...>
 

Hi Dan,

 

I was just wondering why this was an Arp when it didn’t display the typical warped arms of an Arp. Nice one, I can’t say I’ve heard of this one before. That dust lane going from the galaxy’s core to the one o’ clock position is pretty intriguing. Is that Arp 213’s dust lane or maybe an obscuring dark nebula in the Milky Way? Very intriguing.

Arp 213 (IC 356, UGC 2953 and others) is a spiral galaxy located approximately 53.8 million light-years away in Camelopardalis. Much like IC 342, this one is obscured by the arms of our own galaxy. Because of this, Arp added it to his Irregularities, Absorption and Resolution class.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

360 minutes total exposure – 6 hours

 

Imaged October 24th and 25th, 2017 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.

Arp 48 (PGC 4789 and others) is the grouping at the bottom left of the image. These are in the Spirals with Low-Surface-Brightness Companions on Arms class.

 

Arp 88 (PGC 4728, VV 445 and others) is the small spiral with companions to the right (west) of the center of the image. These are in the Spirals with High-Surface-Brightness Companions on Arms class.

 

Arp 119 consists of MCG+02-04-022 (PGC 4748, VV 347b and others), the round galaxy and the other member, VV 347, the odd-shaped galaxy near the center of the image. These are in the E-like Galaxies Perturbing Spirals class.

 

All of these galaxies are located in Pisces.

 

Luminance – 32x600s – 320 minutes – binned 1x1

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

Re: LBN objects - difficulty level?

Hi Dan,

THANKS VERY MUCH!  Very useful data!

I took a chance before seeing your data and
shot LBN 672 last night.  It has brightness 3 according to your
data.  I did get decent images that I think I can work with.

So I probably can image LBNs with Brightness levels 1 to 3.

Thanks,

Howard

Bright is a little bit of a misnomer here. These things range in brightness from 1 (will show up well) to 6 (definitely forget about it with an old OSC camera). This particular one is a 5. I tend to find that 5 and 6’s are rough without a lot of exposure and even then they’re just faint clouds of dust. I have a list of these in Excel if you want me to send it to you.
