What's > AT but < Powernewt? [Re: David Pavlich]       #5563314 - 12/09/12 11:11 PM Edit   Reply   Quote Quick Reply   Those images are stunning. It makes me wonder if the Powernewts have a reinforced structure compared to the Astrotech version that I own. I just don't see how it would be possible otherwise.

[Re: David Pavlich]       #5563329 - 12/09/12 11:25 PM Edit   Reply   Quote Quick Reply   Thanks for the link David. Those are nice photos. I have just recently acquired an at10in locally. The asking price was too good to pass it up and the njp will easily carry it. I'm tempted to get the 2" ASA corrector which is in stock at opt. I just wish someone else had already tried this combo.

[Re: andysea]       #5563910 - 12/10/12 10:39 AM Edit   Reply   Quote Quick Reply   I think the Carbon fiber makes a difference, but the Powernewt is offered in non carbon fiber as well. There are some spec differences between the two. Different mirror spec claims 1/4 wave vs 1/12 wave. Different weights, although the Powernewt is lighter. Different focuser travel. Even if they are both GSO newts, it seems like they upped the specs of the Powernewt. At least that's what their specs imply. I've seen some of the creators images in the CCD forum and they are impressive, but it's hard to tell if they are any better or worse then those taken with the At8in. But I believe them that it's at f2.8, and that means more signal per night. Edited by Footbag (12/10/12 10:42 AM) Post Extras:       andysea sage Reged: 09/03/10 Loc: Seattle, WA Re: Imaging Newts...

I have been looking for images taken with the AT10in but so far I have not found anything. It would be nice to see what the stock telescope is capable of. Unfortunately I won't be able to use mine for a few weeks at least due to the notorious NW weather. My ultimate goal is to shoot at ~f2.8. The question is: should I invest on a fast newtonian or should I just bite the bullet and get either a Tak Epsilon or one of the Officina Stellare telescopes? The Epsilon might be the way to go and it would be cheaper than the OS. Post Extras:       David Pavlich Transmographied Reged: 05/18/05 Loc: Mandeville, LA USA Re: Imaging Newts...

And with the mirror arrangement, I'm pretty sure that you don't need a flattener. David Post Extras:       Footbag Carpal Tunnel Reged: 04/13/09 Loc: Scranton, PA Re: Imaging Newts... What's > AT but < Powernewt? [Re: David Pavlich]       #5565582 - 12/11/12 09:24 AM Edit   Reply   Quote Quick Reply   For some reason that Tak never made it onto my radar. Seems like a very nice astrograph. I also read that it rarely needs collimation and doens't need a field flattener. That just may make it worth the extra $3k.

[Re: Footbag]       #5565681 - 12/11/12 10:30 AM Edit   Reply   Quote Quick Reply   I have seen stunning images taken with the Epsilon. It seems to be an amazing astrograph. I suspect that shooting at f2.8 will make a huge difference. The closest lens is the Canon 400mm f2.8 and it costs twice the price of the Epsilon.
