During a brief break in the clouds... the moon with the astroscan was quite stunning although I only knew Saturn by his color, being a warm tone oblong blob through this scope. I followed up with my 60X910 Monolux (HOC) with the new ep's of 15mm and 28mm and I'm good with the purchase. Very nice in the right telescope... as in one that hasn't been beaten to pieces internally.

This ungluing really must have happened early as there isn't even any dust on the not corrector lens...er... optical window. A perfect storm or beautiful mess.

I bought a Astroscan and needed to "go inside" here we all discuss the procedure:

Yours could be beyond "black out the chip" but you never know.

Anyone have a safe way to remove and replace the corrector w/out wrecking the collimation?

Andy Seronik recently penned an article in S&T on how to safely remove and replace it....oops! - Robert's link already had it!

I'm confused about the "Questar" the the thread title... Is this an inside quip that I'm out of the loop on?

Glenn,

Sorry an awkward playing upon Nave's thread "$100 quandary". I was going to drag out the opening of the package but decided to spare everyone the excitement of believing it would be another "affordable" Questar

Send it back to Edmund. I beleive it is still $35 for a complete rebuild no matter how bad, and that includes return shipping. You only pay the $35 to them and shipping cost to them. Call them to be sure.

Really, like wow. Who would even attempt fixing one for $35. I thought I heard about that before, but never checked it out.

I emailed them to see if the repair policy covers ground glass. If not I'll try to nab one cheap without ep's.

Without paper work is there a way to determine the country of origin or vintage? I found a sticker on mine saying made in China. I assume that makes it a pretty recent vintage. Were early ones made in Japan and mid life ones made in the US and then China? Does the dust cap indicate where it was made? Mine looks like this but there is a current eBay offering that has a different cap.

I would think being made in China would indicate a newer model, though I have no idea when they started being manufactured there. The fact that the eyepieces are Plossls rather than RKEs, assuming they were the originally supplied eyepieces, indicates a newer vintage, too.

Just a follow up on my not at all classic recent Chinese made Astroscan. I wanted to remove the weight that was loose and smashing into the mirror at every opportunity. A very cheap pair of split ring pliers aka keeper removers. Of course the tips were...

Optical window out, loose weight out, now what? The collimation has been compromised fully. Everything glass is a mess. The screw that should help hold the weight in place was making contact with the plastic base just barely... winged it. Apparently the glue all by itself couldn't hang on.

M-13 was actually pretty awesome last night.

Hmmm, I was thinking best friends forever, or at least till the pineapple rots...

but an explosive tropical fruit launcher works too. M-80 isn't that in scorpius?

Actually, if the temps are warm enough, you can whack off the top of the pineapple and stick it in dirt, give it some fertilizer and water and it'll grow! Can't do that with an Astroscan now can you!?

I'm in Oregon dude! Fertile soils, but never pinapple warm. The Astroscan still has a chance here, a few clear nights...it'll grow (on me at least),

At least on the earlier Astroscans, the country of origin can be found molded into the plastic around the lower strap knob hole... will be either U.S.A. or Japan. Not sure if the Chinese version has this, but it's easy to check... if nothing's there, then that would surely indicate a Chinese origin.

Any serial number on this one, Keith? Also, what are your plans for the scope if you decide not to replace the optics?
