ARP 80: Large, high surface-brigthness comp. on arms

[elpajare]

NGC 2633 is ARP 80 from the catalog of Peculiar Galaxies of Arp. It is classified as "Spiral galaxy with a partner of high surface brightness in one arm". The challenge of observation is to detect these bright spots in the northern part of the halo. In the color photo it can be seen well but in the inverted one, below, it looks better.

Whats a clear sky LOL - seems to be ok in Spain 🙂

There is everything, sometimes there are clear and something can be done

It is only possible with EEVA, if I did astrophoto it would have been a while since I would have released

Well done elpajare. I have yet to visit Arp 80. Hoping I can pick up the bright companion with my set up. Mike

I have observed NGC 2633 and NGC 2634 with a 14 inch scope visually. They were both faint but 2634 was the brightest.

Thanks for sharing.

Mark, always good to remind ourselves to take a look at the objects visually. Thanks for that. Mike

Fascinating galaxy and indeed field. I tend not to do much colour work with galaxies but in this case it is really nice that you're picking up the blue of the 'knots' in that galaxy (it's very interesting to compare with the DSS image where the blue is very clear also).

Hi Elpajare,

I tried Arp 80 but only got a hint of its companion. Easily mistaken for a star forming region.

The result depends a lot on the sky conditions.

If it is clear and with good seeing the 8 "of my TSOptics RC they get to capture a lot of detail. If I had a telescope of more diameter it would probably be better but they weigh too much and I can't handle them. I have to settle for this one.

If the seeing is bad ....... nothing can fix it
