ARP 41, NGC 1232 Eridanus

[elpajare]

It Is a spiral with LSB companion on arm. Is mag 10.1, 7.5'x6.5' and SAB (rs)c tipe.

The challenge observation is to see texture in the arms and assymety of the companion.

In the inverted version it can be seen quite well. I have also been able to capture the "object" that Arp mentions probably an HII region.

This galaxy is very low on the horizon and you can only see a few days of good seeing. Today it was.

Hi Elpajare,

Good to see you capturing the companion, supposedly on an arm of the main galaxy - you just picking up hints of it. Below is mine from February of this year. Only just got a hint of the companion, certainly no arm leading to it. Some folk think the companion is just a line of sight galaxy. I did get some asymmetry in the companion but this cold be noise.  Mike

C9.25 @ f6.3  11 x 10sec subs and cleaned up a bit and cropped in photoshop. Poor tracking as well as the stars are elongated. Must try and revisit this one with the C11

Your higher latitude makes it more difficult, anyway it is a good shot

Hi Elpajare,

I have been out there tonight under poor skies, frost on the gear but I could not resist having another look at Arp 41, this time with the C11, @f6.3.  17 x 15 secs, 2x2 binning.

I had to sacrifice some detail to reduce down the noise and I was looking through mist and wood burner smoke.

Much better shot compared to my previous one with the C9.25.

This is much better, I even think you have been able to capture the "object" and NGC132A mentioned in the Atlas of Peculiar Galaxies of Kanipe & Webb.

Your are right, I have indeed captured them. Thanks for taking the time to have a closer look. Mike

Hi,

Here is an image that I got a few weeks ago of NGC 1232 with a 10" Meade SCT, f/6.3 reducer, and an Atik Infinity monochrome camera-60s x10 exposure Bin 1. I enjoyed roaming around Eridanis that evening while it was in view.

Here you see the details perfectly. The 10 "are noticed.

Thank you for sharing and comparing results.

I always enjoy sharing and comparing results - we can always learn from others. Thanks Dick for posting your capture. Mike
