Guest Tweedledum Posted May 8, 2012 Share Posted May 8, 2012 Graham from Astrotec amde me this neat little adapter, M42female to 2"sct, as it is a sleeve I can pair down and get the diagonal onto the optical path. Converting old 110mm Russian Mak lens built like a tabk into a useful scope!!. Thanks Graham. Cheers Link to comment Share on other sites More sharing options...

Guest Kheldar Posted May 8, 2012 Share Posted May 8, 2012 Looking good! I see the word Russian and I panic, is that M42x1 or M42x0.75? Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted May 8, 2012 Share Posted May 8, 2012 Hi Stephen, Don't ask me!... Graham will know though Cheers Link to comment Share on other sites More sharing options...
+Graham Posted May 8, 2012 Share Posted May 8, 2012 That would be M42 x 0.75 Stephen Link to comment Share on other sites More sharing options...
Tweedledee Posted May 8, 2012 Share Posted May 8, 2012 Hi Damian, That looks great. I presume you have checked that there is enough back focus to use the diagonal. Just looks like the focal plane needs to be a long way out. You'll be wanting to try it with the eyepieces I borrowed. Cheers. Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted May 8, 2012 Share Posted May 8, 2012 Hi Pete, Need to shorten slighty to bring the focal plane forward. Graham has blackened & completely threaded the exterior so it fits just like a sleeve, clever chap. The nose on the meade diag is long too but has the 1.25" converter so if the moon pokes out from bhind a cloud I'll give it a go.. Cheers Link to comment Share on other sites More sharing options...
Tweedledee Posted May 8, 2012 Share Posted May 8, 2012 Marvellous, hope to have a look through your new 110 Mak sometime. 2" eps would show vignetting, I bet the secondary spot is only about 1" diameter. Should give some great views zooming through with your 8-24mm Seben. It will make a really nice compact grab n go, despite having a density approaching that of a neutron star What is the focal length? Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted May 9, 2012 Share Posted May 9, 2012 Hi Pete, 1100 so f10, it does have its own secondary moon system as the gravitational pull is immense! . Also have a T-ring for the Olympus dslr, so now its worth a go!! Cheers Link to comment Share on other sites More sharing options...
Tweedledee Posted May 9, 2012 Share Posted May 9, 2012 Lol. Don't even think about putting a 2" ep anywhere near it. The extra mass might cause the hole thing to implode taking the conservatory with it At best your Moonfish might disintegrate forming a ring system around the mak!
