Help a newbie out....

Posted By Pat Plunkett

Hi:

I've used all types of scopes and have owned everything from a Pronto to a Meade 16" equatorial. Currently, I have a truss-tube 12.5" and think I've finally hit the mark (between portability and resolution). I have owned both 8" and 10" SCTs and feel confident in telling you that the 10" is SIGNIFICANTLY more of a pain to cart and set up. The images are better, but not that much better. Personally, if I had $2000 to spend (and wanted the same things you want), I'd buy a decent used 10" Dob AND a used Pronto (or equivalent). You'd be amazed at the images the little refractors give on most "stuff" and the wide fields are incredible. BTW, I would recommend staying at f/5 on the Dob - I think it'll still fit in a Jetta. If you were to get a truss-tube 10", I'd go to f/6...

Good luck and keep us posted!

M31 meets Canon Digital Rebel

Posted By Pat Plunkett

Hi Ivan:

I, too, have a Digital Rebel and have tried a little through the 'scope... How did you hold the shutter down past 30 seconds? Do you have a remote? My only disappointment is that there is no way to connect a cable release or remote flash. I do, however, LOVE the camera - in fact I was out today (37 pictures) shooting icicles!

newbie needs help! does size matter?

Posted By Pat Plunkett

Tom:

Get ye to a star party!!! You can check out the differences in person. I tend to look toward the lower sizes, personaaly, as I like the portability. A 15" is portable, but a 20" is another beastie. Also, you can get by with a stepstool for a 15" and a 20" requires a ladder. There IS a difference visually, but there are too many other factors to consider before going a seeing the for yourself. Again I say...

Get Ye To A Star Party!!!

Recommended First Scope???

Posted By Pat Plunkett

Mark:

I concur with the other guys - XT-6 is the way to go. I got one for my son and we both use it quite a bit. It maintains collimation pretty well, is very portable, and give fantastic views of the planets. I've seen them (used) here on AstroMart for around $200...

P.S. Does this sound like a pet peeve?

LONG focus lens???

Posted By Pat Plunkett

Dan,

The beauty of the moveable mirror, stationary lens is that you can "launch and leave" it for a while whereas the ep projection method requires constant attention. We were able to leave our setup for about 10 minutes at a time while projecting onto a building with some poster board attached. It's actually quite cool!!! Also, I've "smoked" eyepieces in the past using projection.

10" f/5 Starbuckets with Servocat

Posted By Pat Plunkett

Dave:

I have one of Neil's 12.5" scopes and carry it in and out of the house. It's a bit ungainly, but quite manageable, so I'm sure a 10" would be no trouble at all. He can supply a shroud with the scope to block stray light, so that shouldn't be a problem either. As far as set-up/take-down when I need to transport it, it takes about 10 mnutes including collimation.

What is the Problem???

Posted By Pat Plunkett

I'm with Mike above - looks like pinched optics to me. I did some mirror work on a Coulter 13.1" mirror and ended up with the same thing. You say you re-glued your mirror - did you put a nail or something similar in the glue to make sure the mirror wasn't resting directly on the pads? If not, I'd say do it again. Do you have side clamps? If so, loosen them. Good luck!

Wide Field Viewing

I really can't see what you're gaining over a conventional Dob mounting - it looks heavier and, as you said, a little shaky...
