Refractors Reflectors Two Cats A few eyepieces
Quote:Yes, I like the idea of grab handles on a refractor. I also put one on my 6" f/15 folded refractor and my 5" f/8 refract.marty

Quote:Looking good Mel! I almost forgot about a handle on my baby Jaegers . I have to do something about it while I still can
Quote:Yeah Mel you gotta' have grab handles on a refractor. It's the law of the land! Mike
Quote:I feel left out. None of mine have handles. I just finished a 5" F5 refractor Originally designed with a Jaegers lens. I had a cemented 130mm dia Melles Griot Achro with about the same FL. Writing on the side indicated it was 10/20 scratch dig and better than 1/3 wavefront P-V. It has slightly better images than the Jaegers. The image is also brighter since it has 97.5% transmission 500-700nm and The Jaegers is uncoated and air spaced. So it ends up about 82%. Both lenses are good for an F5.
My 6" F10 is next!

Quote:Mike, That is a nice job on your scope! Stock pot handles.... Very ingenious. Are those modded Jaegers focusers?

Quote:Excellent photo-tutorial, Mel. Seems so simple - but if done haphazardly - pain and suffering are the usual result.
Quote: That is a great idea you came up with, Mel. A simple paper device to make sure that the element spacers are in their proper places. Looks like you're rapidly heading to first light, my friend. Bambina
Quote:Mel you knew rhat Jaegers did originally use 6 spacers?? The size of those spacers is giving those old Unitrons a run for the money. Mike
Quote:What a great looking scope Mel ! Good luck with the viewing, I know you will really enjoy the six inch and the velvet black sky with all the diamond chips glistening in the eyepiece.
