You'd need a tall ladder for this scope. I climbed at least a 6' once in the dark at a star party. Not fun. That said, I love Dobs. Have a 17.5 f/4.5 being...
Mark, that sounds like a really nice scope that you're getting. Pretty large aperture, but still a quite managable size. It should complement whatever...
Scott, I also noticed that there is a 10"f/10.5 Dobsonian for sale on AM. Now I love long tube newts but like many others I don't think I should risk the...
Robert, I'll bet that 10" f/10.5, assuming it has a well-figured mirror, could put most apos to shame for planetary observation (sorry, Vic). But alas, there...
To completely take this off-topic. Sort of. I always liked this setup with a 22 inch dob and a VW beetle. http://www.faintfuzzies.com/Telescopes2.html Randy...
The big Dobs require a dedicated owner as they can be logistics nightmares. Talk about tall laders, years ago I observed through John Dobsons original 24"...
Very cool, Randy. I like the 22" scope in a VW concept, but my favorite pic is actually the one with the two guys collimating the 48" dob, one with a ratchet...
You're right, Scott. I missed that one. I never reallized collimating such a big dob would require 2 people and a pair of binos! Makes me appreciate my smaller...
Seeing as how this is primarily a refractors group below is a link to a more appropriate photo. http://tech.groups.yahoo.com/group/ScopeMounts/ The scope is a...

Certainly. I'll check it out in the morning. It's currently 1:30am and I have to be up for my next 12 hour shift in 7 hours. I'll give it a whirl. Tom Mohr ......
Thanks, Scott. Yes, the size is manageable. We considered a 20" but nixed it due to what we are discussing here. Ladders, transporting, setup MUCH easier. ...
I had the opportunity to spend a week around the March (2012) New Moon observing with Jimi on his 48" f/4 scope (Barbarella). What an incredible experience!...
I can't say that I'd ever want a reflector that required a ladder to be used. I imagine that these days, Obsession's most popular scope could be their 18-inch...
The file is too large for Google because it is a scan of an article and not actual text. I have OCRd the text, corrected some of the recognition errors and...
Hi Rich, Here it is. You are welcome. Peter ... The New Baader Planetarium 2" Herschel Safety Wedge Solar Prism offers the finest white-light solar views...
HI MARK, I know what you mean about ladders. About 5 years ago I had some views through a 36" reflector at Stellarfane in Vermont. The ladder was 10 fet high!!...
Danke schoen, Peter! Ich habe mir gedacht dass du das uebersetzt. Thanks for doing that. My tired eyes appreciate your time. I'm pretty sure Rich will...
Help? I have tried several times to post my montage of the eclipse on this site but have been unsuccessful. I was able to post it to my yahoo forum rowing club...
If you are shooting straight through you will need the extension tubes to replace the distance the diagonal takes up optically in the light path. I have done...
spaceweather.com as well as science at nasa are reminding us that there is a partial Lunar Eclipse on the morning of June 4. East coasters have a chance to...
Thanks Ken. What you posted gives the gist of the article which I find interesting. Much appreciated. It also shows the problems with machine translations,...
Faster mirrors. My 22" Webster Dob is an f3.6. Yes, I'm tall (6'4") but even with the tracking platform under it, at zenith the EP is pretty much exactly at...
