Cave Astrola - just how good?

Posted By Rod Mollise

Caves can be very good. Not all of 'em are. Many are--optically, anyway. Like many scopes of that era, the mounts, while they look big, tend to be shaky.

As for resources, I know some people around here don't much like the words "Cloudy Nights," but their Classic Scopes board is a tremendous resource, and there are many folks on there with much experience with every aspect of Caves and other scopes of this vintage who can guide you in restoration.

comet in Lyra?

Hard to say...the focus is real far off... Do you have a better focused shot?

Toronto store, Efstonscience is closing!

Some brick and mortar stores will survive. Namely, those who go out of their way to support their customers. Those who DON'T GET IT will fail. Those who don't understand that to survive in competition with Internet stores who can sometimes offer lower prices, they have to offer their customers MORE VALUE.

New Orion Sirius EQ-G Goto power failure

Posted By Rod Mollise

Assumning the power connection to the mount is secure, and it is not plugged into the HC by mistake, the problem is the HC/HC cable/connection. Could even be your motor control board. For some reason the HC is not communicating with the MC board.

Have some equipment to sell

Assuming this is serious... wink

First off, sounds like you have telescopes, not microscopes. Microscopes are for looking at wee little stuff down here. Telescopes are for looking at way big stuff out there.

Secondly, neither is "big" as scopes go. These are small telescopes. The C90 might bring as much as a couple of hundred bucks depending on condition and configuration (does it have the mount/drive base?).

As for the TeleVue. Depends on which one it is. First thing to do is determine how big it is. 880mm is its focal length. What matters is the size (diameter of the main lens). Depending on that size and the model, it can be worth a couple of hundred to considerably more.

As for the lenses, the eyepieces, how much they are worth depends on exactly what kind they are. Model and maker.

reaching focus

My suggestion would be to cut the tube down.

Not what I would suggest for this telescope (!).

Options? Several makers have auxiliary lenses to bring binoviewers to focus with refractors and reflectors. Check with Denkmeier. A barlow will do it, but you may not want the extra power...

ES 25mm 2" 100 AFOV

Posted By Rod Mollise

That's a good idea. These forums seem even deader than usual if that is possible.

As for the eyepiece, I reckon it will be out when its out. Took a while for the big 9, too. 8)

11 inch Celestron/Meade SGT or larger DOB?

Posted By Rod Mollise

Allan Staib said:

Hi all, I'm getting back into the hobby after many years away. I bought the Meade LS 6 inch last year but it is just too small a scope and I have a limited open sky view which makes the LS features a waste. I plan to sell it on this site and buy a good, used larger scope. (Will of course cost more than I get for the LS 6!) I will be observing and not doing astro photography. For the same money, I can get a good used 11 inch Nexstar type scope or maybe a 14 inch DOB. Any thoughts or comments by any of you with greater experience with both types of scopes? I'm nervous about tracking planets with the DOB at moderate magnifications, say 100 X.



It's really quite simple:

If you are SURE all you will ever want to do is visual observing, mostly of the deep sky, get the Dob. If you think you might want to do something else eventually, get the SCT.

The planets? If your interest is high power planetary observation, get the SCT--or some other scope with a drive. I have tracked the planets at crazy high power with my Dob with great success--and I mean 700 - 1000x, but I am mostly a casual planetary guy.
