Happy New Year! Its very good to hear from you.
I must have gotten this RV-6 in the late 60's-early 70's. Its got to be 35 to 40 years old. I remember cutting a lot lawns to finance it.
When I went to college I had it stored at a relative's garage and then it went to my brother's place when he got married. Now its back. Refractor images are cleaner, no diffraction spikes, but all in all the RV-6 seems to be very good. Its mechanics shows its age but everything works solidly and as it should. Right now I switched all the screws, washers and bolts to stainless steel, painted the tube, made a tube extention so I don't see heat coming of me into the FOV and center spotted the mirror. I guess a mirror recoat is in order sometime in the future, but there's no rush.
I didn't take the mount as its very heavy and I remember it being shaky as well. The OTA works great on my CG5 GOTO mount and is half the weight of my refractor.
For the sketch I used it Dob-style. Much more comfortable to use that way. Cool down time is always a consideration for me as I live in the northeast US. The RV-6's cool down time is very short without a fan.
It held Mars very well at 300x to 400x so I guess that's all I need to know about its optics. Star colors were great. I also had a bunch of Criterion and Celestron silver top circle V eyepieces with all them in like new condition.
That said, my 6" refractor with Chromacor II currently is still my all time favorite scope. For visual, images are more pure in an Apochromat but detail is basically the same.
Again, great hear from you!
