[SkyViking (Rolf)]

Thanks for the comments everyone, I have updated the annotated image to include redshifts for the quasars that I could find data for.
I have also made a stretched image of NGC5792 itself to see what it might look like if we were able to see it from above: http://www.pbase.com/rolfolsen/image/144781667/original

Cheers,

Thank you Rick, it's an f/5, I have updated the image details now

Thanks very much Jorge. I used SIMBAD to find them.

Thank you Andrew, I was thinking that it might be a bit unusual to have that many quasars in such a narrow FOV. I recall from when I was looking for globulars around M104 that there weren't a single quasar in sight, so they are definitely not evenly distributed at least.

I haven't seen an image of NGC5792 before.

Greg.

Thanks a lot Greg, yeah it's not one that is often imaged to say the least. I could hardly find any info on it at all.

Thanks Mike, yeah I just had to give it a bit more time when I got the first frames and saw how nice this galaxy looked.

Thanks very much Allan, I'm glad you liked it.

The galaxy NGC 5792 sure could be NGC 1365 simply lying over on its side more huh?

Your stars look better, did you tweak something?

Mike

Thank you Mike, I made this little image to show how it might look from above: http://www.iceinspace.com.au/forum/s...ad.php?t=92183

Re the stars, I adjusted the collimation a bit, as you'll notice I have chopped a bit off the left and right edges in the image, it's about 75% of full frame. My flats are slightly off now because I played with the collimation, so it didn't look too good near the extreme edges. I have a new set of flats ready for the next image though

Thanks very much Paul. I didn't push the data so much this time, so yes the noise is kept in check.
