Quote:Info you should know about the C6, or any small SCT for that matter.
They were not designed to add a lot of length in accesories off the back end. Tthe shorter you keeep it the better off you are.
f/10 is only nominal and occurs at only ONE single position. Your scope is almost never operating at f/10.
These scopes were not made for use like you see in some photos here on CN, with 2" diagonals, reducers and binoviewers. Put a reducer, a 2" diagonal and a binoviewer on the back end of a 6" SCT and it'll be operating close to 4".
Best used with a 1.25" diagonal (or a short 2" diagonal) too get the full aperture.
With a standard 1.25" visual back and a standard 1.25" mirror diagonal, a C6 is operating near F=1700.

Quote:What this shows is there does not seem to be any binoviewer configuration that gives full aperture. And frankly, I would not use my BV on the back end in a 1.25" diagonal. So, just about any BV configuration I select would result in a loss of at least 14 to 18mm in aperture.

Quote:I wonder how long it will be before this shows up on the used market with stripped out secondary screws, and uneven aftermarket focuser, internal fans installed, the rear cell threads stripped out, mirror locks and a the corrector reinstalled incorrectly. I say 6 months tops!! Your killing me Mike.
Quote:I think in some applications the loss of aperture for binoviewing is negligible - I'm guessing as I haven't done it yet. Terrestrial spotting would be fine and I'm gonna leap here and say the comfort and efficiency of bino viewing offsets the aperture loss on contrasts on lunar and planetary.I'm interested in a lot of your results now Mike !Pete

Quote:Have you actually used the scope yet? If not, you might want to hold off customizing it until you're sure it's a good one.
Quote:Even if it isn't, send it back for a replacement...it is worth exchanging until you get a good one...I did!
Quote:Im glad to hear about your star test success. I would gamble strongly the 1/5 distance had a good measure to do with the SA. Im not really star test savy like Eddgie, Norme or some of the other guys.
Quote:The telephone pole glass insulators work very well when its sunny! In addition you can try a silver christmas tree ornament...it actually works too!

Quote:Well whats great about winter in condo world is a lot of folks are in with the doors shut and no porch peepers checking in on your business. I find I really really treasure the solitude of the pursuit.
Quote:I consider fellow amateurs part of that solitude but when I have to do the twenty questions with passerbys and my fav : How much did this cost?"
Quote:Im betting those unbearable heatwaves of summer bring you steady seeing though much as it does up here in CT. Then the transparency takes a hit but in mag 5 skys its a shrug.
Quote: Didnt mean to sidetrack - back to the thread focus.
Quote:This is so good to read - not surprised its a performer for you too, but glad just the same. Now the real showdown Im looking for is a dedicated 6" Celestron versus the 6" iOptron Mak.
That's gonna be good!
Quote:Very good news Mike. Enjoy that little gem. Make sure you have a Telrad on it!
Quote:Jeez Mike...you've already surpassed my C6 Jupiter observations with 294x! The best I have attained so far is around 175-200x. If you got that out of it and liked the image, I have no doubt it's in the 1/8th range. I think you can breathe easy and Enjoy!

If you got that out of it and liked the image, I have no doubt it's in the 1/8th range. I think you can breathe easy and Enjoy! We can always pump up the power, but will the image handle it well? At 294x, the image was starting to show a bit of that typical "Jupiter doesn't like high power" fuzziness around the edges, but it wasn't really bad at all. I could tell that if the seeing were a little better, and maybe I slipped on an M&SG filter, I'd be able to tease out some fine detail, maybe comparable to what I see in my 8" f/6 Dob. Even last night at 7/10 seeing, I'm confident that if I'd concentrated just on Jupiter and waited for moments of better seeing, I could have pulled out some more detail from that image.But remember, too, that I was looking at Jupiter through an XO 5.1! That might have had something to do with it. Mike
Quote:My little orange tube C6 is also razor sharp with no detectable image shift in the focuser.

Quote: I also took a look at the sombrero galaxy in corvus along with the asterisms jaws and the stargate, all three were excellent views. I also looked at m66 and m67 in leo, trying to see all three of the leo triplets but had to use advert vision to see the third ngc galaxy.
