It's not perfect, by any stretch, but it doesn't warrant a recoat any time soon!

Stats:

12.5" f/7, 88" FL
M727336, April 17, 1972

A youngster compared to the 6"!

Congratulations. These telescopes were too expensive for me when I was a kid--but I read all the ads each month in Sky and Telescope at the Ely Nevada City library.

Hi Gene:

I've been to that library! I read my first sky and telescopes as a kid in the Fountain Valley public library in the mid 60s.

Wow, you know an amateur astronomer is out of control when he needs a crane to move his scope around. Very cool.

One of these would be perfect for that truck!

Pickup crane

Only I'd mount it on the right side behind the cab, since the side gate can fold out of the way.

...though I might tip that poor VW over loading something really heavy from the side! So, back corner of the bed would work, too.

Tim that 12" and 2" mount is so sweet. The envy is overwhelming. Can't wait to see the Jupiter images you squeeze out of it soon. Congrats, what a deal!!

Dangit, I must be browsing some sort of awful parallel-universe L.A. Craigslist, I never see any of this stuff show up

I'm going to go clean the secondary next.

I'm slightly bummed, though. With all that gyrating loding it, unloading it, and putting the OTA on, I managed to pull the wire apart that goes to the dec slow motion. It's happened before, too, as there's some black electrical tape where a splice was made at some point.

The RA light is missing, not broken. As is the little cover over it. And one of the wire's solder joints is broken. So, I've got some solering to do anyway. I'll try to get to that today after I clean the secondary up.

I have to localize Curiosity tonight, but was planning to take the "day" off for the most part, since I've been working pretty steady with only 3 days off since we landed. But since I'm finally getting into the swing of Mars time, I'll be up all night anyway, so it'll be a good opportunity to take the 12.5" out for a spin.

-Tim.

Oh yeah, better figure out which ladder I'm going to need for the thing and put it in the garage next to the scope so I don't wake up the fam getting out of the basement!

So I took the secondary out and cleaned it. While I was taking it out, the mirror end was pointed out into the light...

That's the mirror cell and the great outdoors viewed through the mirror, in addition to the reflection (such as it is) of the sky end of the tube and the secondary.

Oh well, it'll need a recoat after all at some point!

I was thinking I need to take the clock cover off and adjust the clutch, since the scope moves a bit too easily in RA.

The RA circle is on backwards, LOL
