Given a choice I would choose aluminium tube for a refractor. At least 2mm wall thickness and preferably 3mm for a long life without dents. Provided you have...
Our astronomy club in suburban Chicago is considering a refractor as an upgrade for one of our two observatories (the other has a 12" Newt). We want to replace...

Hi Rich: There was a discussion on it about a week or two ago on Cloudy Nights. According to the posts there it isn't quite as good as the 127F6.5 and 152F6.5...
I have friends that view with 180mm AP triplets and others with 12" Meade SCT's and C14's and the C14's knock the socks off of planets for minute details and...
How can you get more detail out of a scope like a C14 that does not have smooth highly corrected optics and on top of that seeing is limiting you between 1...
Hi, Nothing can give a answer? who had built homemade folded refractor with 8-12" f20-30 ? homemade mount is no problem for me! i think,8 inch is not enough...
Hi Mark, I hope your observing site frequently has excellent seeing. Rich...

Hi All, Has anyone in the group used the Star Chaser Refractor from Astro Engineering ? I searched the archives but couldn't find no mention of it in there. I...
Hello, I am a new member to this group and would like to tap into any wisdom regarding a topic that may be old to some of you. I am looking at refractors in...
The stories you had heard about Oil leaking is a bunch of nonsense. I have owned Oil spaced APO's for ten years and not one drop of has leaked. I don't even...
FWIW, I've had mine out in -20 temps with no problems at all (for the scope, not me!). The oil spaced objective may actually have an edge in temperature...
... A month or two ago one of the groups I read had a mention of an AP oil spaced objective having a problem with oil discoloring. I'm sure if it was a common...

Thanks to those who responded to this post. BTW, I also read about Roland using commercial vegetable oil in some early models. I also read that the capillary...
Tom, It seems that Roland used several different types of lens configurations. About a year ago, I e-mail Astro-Physics about my 6" f/9 Starfire lens, which I...
Hi Steve, I think that Roland has produced every type of triplet in the past. Oiled, air-spaced and cemented were all produced, in the 80's and into the 90's....
