I was looking for something a bit different - so I decided to image NGC 7090.

Its certainly a challenge - its dim at mag 10.5 and tiny. I've spent a fair bit off time on it and I think that it doesn't repay further investment.

This is about 5 hours Lum and 3 hours each of RGB. Lum is unbinned and RGB is binned x2 - all subs are 300 seconds.

I'm sure I can process this better. But I'm moving on to something a bit larger and better suited to my rig.

The one interesting feature of this field is the number of faint fuzzes. I saw a few and decided to use the Annotate Image script in PI. I've attached the annotated image - as you can see, there are plenty of PGC galaxies lurking around. I wasn't planning on posting a higher res image on my PBase site but if anyone is interested, let me know and I'll put it up.

Thanks for looking

Pete

Excellent Pete, love your work with that rig and.. less than visually spectacular objects are just as valid as imaging targets mate :thumbsup:

mag 10? That's extremely dim!

Nice work, Pete! Surface brightness is only about 22 mag/arcsec2.

Cheers,
Rick.

Thanks Mike - the challenge now is to improve my processing skills.



It is - even with all the time spent on it, there is precious little detail in the galaxy.



I hadn't appreciated that Rick - the pic in CCD Nav was nicely resolved. That explains why I struggled with it.

Nice image Pete. Some nice fine detail in that distant island universe.
