CTB1 Supernova Remnant in Cassiopeia

[kor]

To go with RickS's awesome CTA1 (https://pixinsight.com/forum/index.php?topic=12015.0), here is CTB1.

CTB1 is a supernova remnant in Cassiopeia and part of it is also known as Abell 85 (the planetary nebula list, not the galaxy cluster list) and LBN 576.  It is about 30 arcsec in diameter and is very dim. Even when stretched considerably, it doesn't show up in my green and blue stacks and just barely in the luminance and red.  H-alpha and Oiii show it very nicely.

This is 125 hours of data captured over a six month period from 5 locations:

• LUM: 140 x 180 sec
• RED, GRN, and BLU: 72 x 300 sec
• Ha and O3: 100 x 1800 sec

All processing was, of course, PixInsight.



See https://www.kor-astro.net/ccd/CTB1/CTB1.html for larger images and details.

I hope you enjoy it - Shane

PS: If anyone has any sources for names of more of the objects in the frame, particularly the small dark nebula on the remnant ring at about 4:30, the cool H-alpha loop on the right edge of the image, and the larger dark nebula near the bottom left and top right corners, I'd love the see them!

Wow!  That's a huge investment of time, Shane.  Well done!

If you save a copy of the image that has been plate solved you can load it into the Aladin Sky Atlas and then choose the NED and SIMBAD databases to identity all the cataloged objects in the image.
The objects can then be sorted by type or any of the other available fields.

Thanks Cosmick,  I'll give that a shot tonight.

I should also have mentioned that, like most things, this can also be done in Pixinsight - by loading extra catalogs into the Annotation script.
As I have never successfully completed any operation with spreadsheets or databases I am unable to help with this and I have not seen any repository of custom catalogs.
