Now THAT'S one-shot colour

[pete_l]

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 ...

[ronin]

Oh hell, No!

How much ????

[RichLD]

I've just got my dual rig sorted and was really pleased with it - until I saw this.

I want one! 

[MarsG76]

oh what?... no.... what?

I imagine about 2 kidneys and a first born.

Either LRGB or HII, [NII], [SII], [OIII].

Getting all 4 alligned might be fun, I don't see any adjusters.

No software to coordinate imaging? Could be an issue if you want to dither.

LoOKs more like a rocket launcher than a telescope... ?

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.

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!

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.

Ha ha...

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.

Looks like a must have for Les Granges Astronomy Holiday camp. Welcome to Olly's holiday camp / the camp with a difference / never mind the weather / the processing takes forever...

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. What a project!

It's nice to see you can do leading edge science with commercially available kit. Canon 400mm lenses and Software Bisque Paramount MEII and good sky conditions.

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!

I think they are standard coatings. I recall reading about them at some point on their latest high end lenses.

Those Canon lenses make a Tak scope look cheap, I believe they are 400 mm f/2.8 at nearly £10K a pop.

I wonder if the photographer who took this portrait shot was left feeling a little inadequate in the lens department?

[Alien 13]

Looks like they have a Canon lens as a guide scope too, wonder if they got a discount

Discount?  They probably got a whole production run.

What you don't see, is that they actually used the other 24 lenses to take this.

Its an awful lot of fluorite, I make them around 140 mm for each objective.

Unless they plan on handholding, I hope they remember to switch off the IS when it's on a mount!

Dragonfly? I think they have a bit to go until there:

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.
