pete_l Posted July 9, 2017 Share Posted July 9, 2017 (edited) While looking for something entirely different (honest!) my gaze fell upon this. It makes you wonder (at something like €2000 per tube+camera) how many more OTAs you could pile on ... Edited July 9, 2017 by pete_l 2 Link to comment Share on other sites More sharing options...

DaveS Posted July 9, 2017 Share Posted July 9, 2017 Either LRGB or HII, [NII], [SII], [OIII]. Getting all 4 alligned might be fun, I don't see any adjusters. Link to comment Share on other sites More sharing options...
andrew s Posted July 9, 2017 Share Posted July 9, 2017 No software to coordinate imaging? Could be an issue if you want to dither. Regards Andrew Link to comment Share on other sites More sharing options...

Could be an issue if you want to dither. Regards Andrew Yes, surprisingly none of the software packages even support two cameras and dithering out of the box (apart from APT which unfortunately doesn't do re-focusing yet). Maybe it's too small a market. Link to comment Share on other sites More sharing options...
ollypenrice Posted July 9, 2017 Share Posted July 9, 2017 (edited) I wonder if they've tried multiple rig imaging? It strikes me as unlikely that the tubes will, in fact, be perfectly (or near-perfectly) aligned. None the less the principle is a good one and very productive where I live!

Alien 13 Posted July 9, 2017 Share Posted July 9, 2017 I do like it but would prefer canon lenses like these. One other thing that has puzzled me is why not shoot CMY instead of RGB, its twice as fast. Alan 4 Link to comment Share on other sites More sharing options...

ollypenrice Posted July 11, 2017 Share Posted July 11, 2017 Looking again at this system, does it, perhaps, have a 'rings within rings' design to allow for individual alignment? Hard to tell from the picture. Olly Link to comment Share on other sites More sharing options...

The Admiral Posted July 12, 2017 Share Posted July 12, 2017 (edited) Just 10 lenses? Is that all! I knew I'd seen something with a huge number, and finally managed to track it down (thanks Google). How's about 24 (well 48 as they come in a pair) ? It's part of the University of Toronto's "Dragonfly" project, of which Alien's picture is an earlier incantation. More can be read here.

Regards Andrew I was a bit unsure whether they were standard lenses, on account of the statement "It achieves this using commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses." as though the coatings were special. Depends on how you read it. Even so, the expectations of its performance are considerable! Ian Link to comment Share on other sites More sharing options...

Alien 13 Posted July 12, 2017 Share Posted July 12, 2017 Those Canon lenses make a Tak scope look cheap, I believe they are 400 mm f/2.8 at nearly £10K a pop. Alan 1 Link to comment Share on other sites More sharing options...

Hard to tell from the picture. Olly I think I read (could be mistaken) that they can be individually aligned but that they specifically have them slightly misaligned (or at least are capable of) so that they can get down to sub-pixels. The latest models of Canon (and Nikon) lenses have nano coatings which help to reduce glare/reflections, again that is what I have read, it has a slight improvement in contrast compared to previous versions of the lenses.
