Hi Jim,
You need to come out to AZ! We winter just north of Tucson and the seeing is excellent! They've had a lighting ordinance in effect for close to 30 years or so because of all the observatories out there. I'm originally from Maine and summer there now, but the summer seeing is not ususally very good... and I stood outside in -5°F many a night observing and trying to do astrophotography back in the 90's and always wished I was in AZ! What do you use for a travel scope? I have a Williams Optics Z73 which is much easier to carry around than my 6" Newt. Looked at your photo galleries... very nice. I used to be very heavy into astronomy in the 90's and kind of got out of it for a while. But got the 6" newt for Christmas last year and it was shortly followed by the WO Z73 as the 6" just wasn't going to be a good mobile scope. I have a few pics but haven't gotten into much stacking or post processing yet...
What I've gotten so far is here.
I also checked your blog link and trailer mods. Love the dimmer idea and already downloaded the printer link for the switch mount and sent it to my nephew to see if he could print a couple for me (main cabin lights and awning switches). I've done several of the same mods (Have brought my TST system to 3 campers now).
