Sh2-91 is also known as LBN 147. It is the southeast part of a much larger (about 4 degrees and roughly circular) supernova remnant known as SNR 065.3+05.7. It kind of brings to mind the famous Veil Nebula SNR, but it is comparatively pretty dim and in a very busy star field. It is in the opposite corner of Cygnus from the famous Veil.

 

Also in this image is Min 1-92 (Minkowski's Footprint), a Post-AGB Star (proto-PN) or pre-planetary nebula. In this image, it is so small, it simply looks like a slightly elongated star. It really needs a much larger image scale.

 

Because of the different scope / camera / filter configurations I use and my target sequences, the image capture was started with the ATIK camera and finished with my SBIG camera. Hadn't done this before, but it gave me no problems.

 

Image and details can be accessed at the link below (or by clicking on the Sh2-91 thumbnail image below); full size image can be accessed from the image webpage and has an image scale of 2.53 arcsec/pixel. The annotated image link is provided below, but that can also be accessed from the image webpage.

Impressive resolution!

I am with Mert on this as I don't remember the last time I've seen an image of this target.

 

Great job as always Jim.

Nice job I was not familiar with this one and I have been working my way through the Sharpless catalog.

Looks great Jim. Very pleasing image with the color balance of SH-91 and the star field.

Thanks for the comments folks.

 Are you going to go wide to get the whole SN? Or just get Sh2-91? You may still have some time this year, otherwise it is something to look forward to for the next. year.

 

Best of luck on your project.

I'm going to do a small mosaic, 2 panes to get SH-91, the whole area is a big project!

Yesterday night I tried SH2-129 but that squid is missing!!! ( only 45x120 seconds per pane )

That is a very dim object.

I did a 3x2 mosaic of this SN (using 100mm Esprit).

It was a loong project crazy.gif
