Quote:But, I think you will be pleased Mike, although if your Mak was of good quality, I'm not sure how you will rate the C6 for planetary in comparison. Mine does well, it shows detail besting a fine Tak Sky 90 and a TMB 92L I had previously.

Quote:Last night I ordered a C6 from High Point Scientific - along with a Bobs Knobs kit - for $403. After a discount from Celestron, it was like getting the Bobs Knobs for free. I've been in this hobby for over 40 years, but I've never owned an SCT. I've owned Newts, refractors and Maks, but never an SCT. The C6 will be my first.
I had been thinking about buying a C6 for over a year now. I kept putting it off, since I already have a 150mm Mak. However, the Mak is about 4 lbs heavier and takes about 1-1/2 hours to acclimate ... if it ever really does here in "wait a minute, the weather will change" Maryland. I might decide to sell the 150mm Mak. It is a nice Rumak, but I seldom use it.
I have a 90mm Mak I usually take out for grab-n-go, but I wanted something with more aperture that would still be easy to take out and quick to setup.
I had been concerned that the price might go up on the C6 or Celestron/Synta might stop selling them. I know it wouldn't make sense to end such a popular product, but I've seen sillier things happen in this hobby. I was also hoping that maybe the price would go down. But after a year of waiting, it didn't seem like that was going to happen. So finally I pulled the trigger last night for the C6. (Now watch for a price reduction! )
I already have a mount for the C6 - my Voyager Alt-Az. Judging from threads here on CN, the Voyager seems to be a good match. I have a CG4 GEM with tracking, but IME, GEMs are not so good for grab-n-go. They are heavier, larger, more cumbersome and more complicated to setup and use than comparable alt-az mounts. If I ever feel like tracking the Moon or planets, I can bring out the CG4. But I doubt if I ever will for the C6. IMO & IME, GEMs are not optimum for true grab-n-go.
I doubt if I will order an FF/FR for the C6. I've read through several threads on this topic, and so far have decided against it. Although the off-axis field will be improved, an FF/FR will reduce the sharpness on-axis. I intend to observe a variety of objects with the C6, including planets, Moon, DSO and double stars. I don't want to bring along another accessory I need to remove/replace when I switch to different objects during the same observing session. I want to keep the setup simple for grab-n-go.
For the time being I've also decided against installing a 2" visual back and adapter. The CA of the C6 is only 27mm. I don't want to introduce vignetting into the optical system. Also, a 2" diagonal and adapter will add weight and length to the scope, and might get hung up on the mount when I'm observing near zenith. If I change my mind, I already have those gizmos that I bought for the 150mm Mak.
In fact, I might just put my Baader Hyperion Zoom in the kit when I take out the C6. To maximize low-power "wide-field," I'll include my Orion Ultrascopic 35mm. Its field stop is 28.9mm, so vignetting will be minimal.
I'll probably replace the stock 6x30 straight-through finder. I'm considering mounting my ES 8x50 finderscope instead. It's a straight-through finder with an erect-image that is non-reversed. If I use this, I won't need a Telrad/Quikfinder/Red-Dot. I can combine the functions of a Telrad and optical finder in one unit. But it remains to be seen if the weight and size are compatible with the C6. Also, the ES finder has an Antares type mount, not a Synta. So I'll have to deal with that problem.
.... back yard astronomer ================= Don't forget to look at the moon often. Its a play ground of fun if you throttle up the magnification!
Quote:Mike one of the clinchers for me on getting a C6 was Larry Carlinos review of his saying it was every bit as good as his Synta Mak of like sized aperture.
Quote:These scopes are so close in revealing lunar and planetary detail that it’s difficult to choose one over the other – both are very good.
Quote:A Takahashi FS-102 fluorite APO refractor showed essentially the same level of detail [on Mars], but with superior contrast and slightly less brightness at the same magnification.
Quote:By counting stars in the beautiful Double Cluster in Perseus, I was able to determine that the C6-S provided about the same light grasp as the 5-inch Takahashi APO, and ,surprisingly, almost the same as the 6-inch achromat.
Quote:Ah! So you've finally given in and come over to the centrally-obstructed side!Mwahaha!

Quote:I don't think you need bobs knobs. The collimation screws have very little tension to them so striping the philips heads will not happen. In 2 years I have collimated my C6 2 times and each time collimation was off very little (and I star testevery time I observe). I can guarantee that if you replace the screws it WILL need to be collimated.
Quote:Cool down times are faster with the corrector plate exposed. I use a surgical hair cap to cover the dew shield while the scope is cooling unattended. It's like a shower cap, but allows air in while keeping the corrector plate clean from dust and air-borne debris.
Quote: Oh yeah; in cold weather the cover does not fit tightly when you pack-up for the night - in fact it will fall right off. I placed adhesive felt next to the tabs to remedy this.
