Sh2-173 H-alpha

[ChrisLX200]

Captured back on the 10th August 12 x 1200s using 3nM Astrodon Ha filter, this is a fairly faint Sharpless object in Cassiopeia. Not much to say about it really other than the fact it looks like a Teddy Bear looking out at me.. :-)  Not sure it's worth the time to complete SII and OIII channels as other sources suggest there isn't any signal there, so I will likely leave it as a mono image.

Or an old english sheepdog?  If S11 and O111 are not strong enough, it would be interesting to see it with some RGB (at least for the stars.)  Or is it just too faint?  

I like it!

Thanks folks!

Chris: Yes it is very faint, that is 4 hours worth of H-alpha of what would be by far the brightest channel. I have not seen the faintest trace of OIII or SII on other images of this object so all that would happen is it would go Red/Yellow (depending on chosen palette). I could add RGB stars and that would not take long to do. It is one of those less often imaged targets!
