ASTRO: Sh2-170 in halpha
I am just getting started on this.
I went to the Ranch on Saturday and shot this Saturday night. I only got 2h 40 minutes total exposure so it is a bit dim right now http://www.narrowbandimaging.com/sh2...s4_ha_page.htm |

That is very good for only 40 minutes on something that faint! I put off doing that one it was so faint. Though last night I put 3 hours in on something even fainter. It has no narrow band emission as it is glowing dust not gas. I need several more nights. 3 hours was all I had between moon set and dawn. Worse tonight of course. Skies don't look promising either. Good luck on getting more photons on this Sharpless target. Smoke a problem at the ranch? I have it some nights here. Calms seeing and doesn't block all that many photons so rather a good thing for me when I get some smoke. I don't want the fires however, just enough smoke to calm seeing.

That makes more sense! the smoke is completely gone. the skies were beautiful but there's a bit of moon... Yeah, that is a pain. But the clouds that just covered it up are even more of a problem! Looks like tonight is a loss. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
