Want to borrow - linear binoviewer

Hey astro peeps, I have been using standard binoviewer for some time and absolutely enjoy the views. Recently linear binoviewer are gaining a good attraction.

Re: 3D printing mounting rings

there are certainly some designs available on thingiverse which can be adapted. but more importantly wanted to get some advice from local folks who do 3D printing, spool, printer model etc.

Re: Comparison between 102achro, ed100apo, mak127 SkyWatcher

very nice comparison. I think the ed100 doublet is fantastic scope. though I also loved the orion 120ST. despite being an achromat, it was a fun scope, fast at f/5, short and easily to grab and setup. but I had better views through the ed100 doublet of the luna. I have pondered a number of times abo...

I used the same for az-gti and asi air pro ...

Re: Comparison between 102achro, ed100apo, mak127 SkyWatcher

interesting.. I had a different experience. The ED100 f/9 doublet have such good views of jupiter/saturn and moon that I was tempted to upgrade to sw120ed. but I havent tried the 5mm bundled eyepiece. I use a 10mm UFF or celestron 8-24mm zoom most of the time and with them the views are excellent.

Re: Eyepieces from binoculars and modification.

very interesting.. are these eyepieces as sharp as the ones designed for telescopes. I see a good number of posts using microscope objesctives in telescopes (with some 23.5mm to 1.25mm adapter), but a binocular eyepiece is definitely new for me.
