SH2-170, the small rossette
« on: 2011 October 18 12:04:19 »
Hi,

This is a unknown object, but I think it's a very interesting one. It's also quite faint, specially in OIII.

Hope you like it, and as usual, any comments are welcome.

Regards,
Manuel.

I don't know exact number of images (about 12), 900s exposure each, APO TMB 135/780 with flattener, camera G2 8300 (Moravian Instruments), Ha filter 13nm - Astronomik. Equipment was used remotely from my friend's backyard observatory.

Yes, that shows that the object it's not exactly bright. The most brilliant part is about 200 counts above the background level at 30 min exposures.
