Which reminds me ... EPHRAIM! You were looking at building your own Dob - this would get you primary and secondary mirrors, primary mirror cell, spider, and...
It didn't work for me until I logged into Cloudy Nights with the remember me checked. Then it worked the next time. Worst thing is now I think I need a 10"...
... A perfect diversion for a rainy afternoon! Had fun just zooming in and out and looking at different areas of the sky. I like how nicely emmision nebulae...
Whilst digging around online for opinions on Sky Atlas 2K vs. Uranometria 2K, I came across this free PDF star atlas for download. Looks pretty complete and...
Here's a fun little project, especially for kids - or for adults if you need yet another gew-gaw sitting on your desk. Links for printable PDF files are at the...
Great timing Craig. My star atlas got wet one too many times and had to be trashed a couple of weeks ago. This is actually pretty nice so I'm going to give...
Those are amazing Tim. If I ever get shots that good I will be very very happy. -Jeff ... From: Tim To: NWGAA@yahoogroups.com Sent: Sunday, October 25, 2009...
Which leads me to ask the group - does anyone have a recommendation on printed star atlases? I'm looking for something that is appropriate for a 10" reflector...
I really like the Pocket Sky Atlas for field use, very readable and a great convenient size too. From what I've read, the Sky Atlas seems to be the gold...
Mine was a Sky Atlas and I really liked it. I thought they were more resistant to dew but mine got a few heavy hits over the years and I opened it one day to...
... Craig, The Sky Atlas 2000 and the Pocket Atlas are similar in scope (sorry), but unlike the 2000, the Pocket Atlas doesn't take half an acre of table space...
Alex, Thanks. Please do bring Uranometria out on November 14th if we manage to escape inclement weather. I'd love the opportunity to scope it out (sorry). I...
The Collins Atlas of the Night Sky is decent,too, plus includes Moon maps. Alton ... From: ngc2070 To: NWGAA@yahoogroups.com Sent: Sunday, November 01, 2009...
The pocket sky atlas has one problem. The galaxies are shown in red! So, what happens when you use a red light with it? That's right, they disappear! Who...
Hello All, I'm sure the answer to this is a simple "try it and see", but I thought I would throw it out here. Basing the wattage of a heater strip for an 8"...

I saw your post Lynn and I was afraid to reply without doing the math first and haven't had time to do so. if I remember correctly, myu unit peaks at about 5...
Hey Dan, Yeah, I thought 20 sounded really high too, but I researched the commercial heater strips for an 8"-ish scope and they were in the 17-20 watt range....
Well, I looked everywhere and couldn't find my original drawings and board layout so I started over. I hand sketched a quick schematic and took some shots of...
Thanks Dan. I'll print those out and take a look at them. My first run with my hardwired hi/low switch worked out pretty well, but I know a PWM controller...
