Fremont Peak 12/18/2004

by Richard Crisp

I was joined by fellow imagers Jeff Crilly, Phil Terzian and John Gleason and the Peak eyepiece king, Peter Natscher for a very pleasant first quarter moon evening on the Peak.

We were all concerned that wind would get us so we set up near the restooms in the sheltered area.

the weather was in the high 50s with very low humidity all night. there was a light breeze that picked up a few times but overall it was a pretty calm night up there.

Transparency was good and seeing was maybe a 5 or 6 on a scale to 10 at the beginning of the night. As midnight approached the seeing had improved.

I was using my AP180EDT with a 0.75x reducer and IMG6303 camera for imaging. I had it mounted on my new AP1200GTO mount that only arrived on wednesday.

I decided to re-shoot the "waterfall" region near NGC1999 in Orion. The intent is a tricolor emission line image such as I did back in February ( http://www.narrowbandimaging.com/herbig_haro_34_page.htm)

I ended up shooting only Ha last night.

here's last night's result
