Okay, so I picked this Tak fluorite refractor up at a pawn shop in Rialto. If anybody remembers when I bought the Mayflower in Echo Park, from the guy who originally wanted to trade for a rifle, this place was weirder than that! The shop had bars on the windows and doors, and when you stepped inside the front door, you were in a cage. The guy behind the counter had to push a button to let you out of the cage.

Anyway, I gave the scope a going over, tried to talk him down a bit on his asking price of $1K (as a matter of principle, of course!), and ended up agreeing on $900 plus tax, which put it almost at his asking price.

I just set it up, and am waiting for the sun to go down. There are a few things I'll need to tend to when I get home, but for now it's functional. First, some pics:

Okay, few things:

*the cool chrome knob that holds the counterweight is broken. I have several Tak counterweights with this screw at home for my EM-10, so I can use one of those while I look for a replacement.

*one of the finder scope screws is broken off in the bracket. The broken screw and nut is in the case.

*the screw-on cap for the center of the lens cap appears to be missing.

*That odd plug in the polar scope does come out and the polar finder does appear intact - yay! So I'll take that plug out and put the green plastic cap back on.

*Came with the Tak star diagonal and 3 orthoscopic eyepieces - 7, 12.5, and 25mm. No barlow. .965 only.

-Tim.

Tim, great catch! I hope to own a Tak one day. There's an astrograph about two hours away, but WAY out of my budget.

Saturn is gorgeous! The only hybrid diagonal is a plastic one that came with a
90s tasco 60mm. At least the prism is glass! So I'm using that so I can use a favorite UO flat top 6.8mm ortho, that seems to show the
Most detail without losing contrast too much.

The mount
Is very stable. I can keep the planet centered while holding the ra cable and not jiggle the image.

Just switched back to the tak .965 diagonal and 7mm ortho and I like that combo the best. First time I've ever used quality .965 eyepieces! They're quite good!

It also has a very nice polar finder, but with just two rings to the reticle. Took very little time to get good alignment. The illuminator is missing. It's a separate part, like it is for my NJP mount. For the NJP, I just turn on my cell phone and hold it near enough to see the reticle without washing out the sky.

About the RA control knob. Not only was I able to hold onto it while viewing, and not shake the telescope, but I was able to rest my arm on the tripod cap while holding the knob, still without shaking the scope!

I'm going to put some mylar over it for the eclipse today.

-Tim.

I forgot to comment on the finder. It's not only huge, it's very nice too!

It needs repainting, though. Abundant chips from the alignment screws. Probably mainly from having the one broken off. When I got the scope, the finder was loose. I finger tightened the screws so I could align it. Since the broken screw was still in there, it was possible to adjust the other 5.

Tim,

That is a fantastic scope, congratulations! The FC 76 on the P2 is such a nice classic scope. It's performance on anything within it's lightgrasp is stunning. I had my first view through one of these in 1989. Could not believe the clarity of the image.

Hi Tim,

I'm glad one of us got it. If I had an extra $1,000 I would have bought (okay, instead of posting about first!).

LGM

PS. Do I get a finders' ,,,,not a fee, but a peek?

Hello Tim,

I knew you would like the view thru the scope. Splitting double stars at or above the theoretical limit is a real treat in this scope.

The scope being f8 will perform it's best especially at higher powers using the best prism diagonal you can get. Unless I'm using 2" eyepieces. I use the Baader T-2 Prism Star Diagonal, best prism I've used. On good nights, 100+ per inch is no problem. The scope loves to be pushed to it's limit.

Enjoy,
Stephen

Tim,

Clint (Caveman) told me about your acquisition while we were observing the eclipse out in east Palmdale earlier today. Now I see what he was talking about when he said what an amazing find you made. Congrats!

(How was the eclipse from Cedar City?)

Great find. Congrats
I think you might still be able to get the R.A. drive from Tak.

Thanks for the congrats everybody. LGM, by all means you can have as many peeks as you want! Thanks for posting about it. I wouldn't have even seen the ad, because I search for "telescope" in the title and with pics (tired of sorting through all those car ads with telescoping steering columns!), and the seller didn't have "telescope" in the title. Only "Takahashi FC-76 refractor"! Yikes!!

We saw the eclipse from about a mile south of the centerline south of Newcastle, about a half hour west of Cedar City. Tim Hogle had scouted out a spot off the road on a dirt road up the side of a hill about 200 feet above the floor of the valley. We had a completely clear, cloudless, good seeing view of the entire event! Fourth contact occurred seconds before the sun started to set! I caught the whole thing with my Coronado Solarmax II on a super polaris mount with iOptron Gotonova kit installed, using a Pt Grey Scorpion 2MP firewire monochrome camera and Astro IIDC on my Macbook Pro. I set it to take a frame per second, and so the 16-bit video is about 34GB and over 7000 frames (I set it to take a 10000 frame video just in case, and simply stopped it when the sun disappeared below the horizon). At the very end, the gotonova HC beeped and said that the scope was pointed below the horizon, and it stopped tracking! So for that segment, I had to hit the RA fast button to keep the sun centered.

I also set up the Tak so people could watch the event in white light. I didn't make a full-aperture filter, just one over the hole in the center of the lens cap. But the definition on sunspots was amazing, and the scope got used continuously by others in my party throughout the eclipse.

I've got to drive to Tahoe today, but will try to process some of the video tonight and post it in the Solar forum. Maybe even my facebook page!

-Tim.
