Hi all, Many thanks for the help! Kim, could you give us some specifics about that spot in Skull Valley? Best wishes, Joe --- On Thu, 9/9/10, David Rankin <David@rankinstudio.com> wrote:

Light pollution really kills deep space astrophotography. I think that it is because a lot of the visible light coming off of the objects is the same wavelengths as the light pollution. You get this fog in the image and when you try to remove it, it starts to eat away the data from the object you were shooting. I have tried LP filters with little success as well. One way around it is to shoot in HA only, as it wont pick up any of those wavelengths. I don't have an HA filter for my dslr yet :(. I have never been to spoc though, may come out there anyway.
What is the Ealing?
Cheers

Here's a question for you expert imagers: How does moderate light pollution such as at SPOC affect both the imaging process and the final product? Can you achieve the same results as you would from a very dark sky?
Joe, I've been to Skull Valley a few times and observed from a spot near Horseshoe Springs. There's a small hill on the opposite side of the highway east of the springs where you can get a little elevation, above the low-lying moisture. The hill is rocky so even if the surface is damp I don't think it would be muddy. Skull Valley is also only about one hour from SLC.

Have you considered the Ealing at SPOC?
We got some nice images early in SPOC's history with it and an old ST-6 I gave the club (ST-6 is for sale, BTW). I've often wondered what could be done with the Ealing and one of the more modern imagers.

Hi Friends, David Rankin and I are considering heading out for some
astroimaging Saturday evening. I am fond of Lakeside because it's pretty dark and it's only an hour from SLC. Do any of you old hands like Jay Eads have an opinion about whether it'll be muddy or humid then? We've had rain recently and I think more is on the way. If not Lakeside, is there another place sort of close to SLC where we would not have to deal with moisture in one form or another? Many thanks, Joe
