For those of you that enjoyed my pictures taken in Costa Rica http://www.robhawley.net/CR07/ Gary Seronik describes the barn door tracker I borrowed in his...
Hey Rob, I don't understand. You used the barn door tracker in Costa Rica, so you presumably already have it. What is (going to be?) a summer project for you? ...

Gary Seronik from Sky and Telescope leads the Costa Rica trips. He brought a prototype of his tracker to Costa Rica this year. I had the opportunity to use...
Doh! I knew that. Thanks, Richard. Paul ... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam...
The literature that came with the 20Da stated that 1) The camera needed to be idle between exposures for at least as long as the exposure 2) The max exposure...
They sound about right to me Rob. 1) If you use the automatic dark subtraction feature then the camera needs to take a dark frame after each exposure (of equal...
Shooting the wide-angle photos in Costa Rica was fun (or at least seeing the results was). I ordered the parts for one of Gary's mounts. I also ordered a...
Paul Alsing posted this to TAC. I was particularly interested in the write-up about Figueroa Mountain, which would be a great site for an imaging party. ... ...
Hi Paul, It looks like you guys sure have some great choices of imaging sites in Southern California. When I was in college at Caltech one of my favorite...
I've been up to Palomar several times but not Wilson. Not sure how long a drive it is from SD. We have lots of great sites, which makes it even more...

Hi Guys, Is anyone else going to post an image of M51 or M101, our latest challenge objects? I posted my M101 a while back and I've got my M51 data but just...
I'm working on M101 but still need to gather the RGB. My scope is out now but it's hazy and not very steady. Last months conditions were bad for me, I'd like...
Well, it's not up to the quality of you guys, but here's my attempt on M51 from 22nd March before it disappeared from the viewable sky from my apartment's...
Hi John, After your disclaimer about your imaging conditions and such I was expecting a smudge <G>... but I think you did an excellent job! I really like your...
That's a fine image John, I'd be interested in hearing your thoughts about the Art-11002 and also please post some images taken with the R optics when you get...
Last night skies were a bit darker than usual with relatively smooth seeing, so I revisited M81 & M82 to get a shot with the new scope/camera properly aligned....
Thanks, Paul. I am clawing my way up that learning curve, but a lot of it has to do with the skies were particularly dark last night and I didn't need to...
Hi Jim, Those are fine pair of images! I think you did a great job acquiring the data and processing it. More clear nights are expected so I suspect you have...
Thanks Ray - I like to get my disclaimers in early and often ;) Now I've got the Dec backlash issues sorted on my AP900, the next step is working on the PEC...
Thanks Iver, It's still early days for me with the ART11002, but it's looking good so far. I had the ART285 before this and that was great. The only slight...
Hi John, Yes, you can use a star to the SE if that works better for your location. Just try to do the calibration near 0 dec in the SE. After which you could...
Well, John's great image of M51 reminded me that I have data sitting on my hard drive from my AP160 in New Mexico. So, inspired by his image I took a little ...
