Can someone post a link of the scope before I pass out hyperventilating?

Oh please please please say yes! :) joel

Hi Roland, Any plan to make a small version (10" or 12") of that for Mach1 users ? ;-) -Kai

Hello Roland, I do use http://www.astro-physics.com/tech_support/mounts/protocol-G.pdf as a reference for the mount API but cannot seem to find the info on how to read/write the PEM table ? Is

Rolando, Chris Go posted a seven-min video of the first day at NEAF and at about 01:58 of the video I see the new scope. Speak about going au naturel (not you, the new scope) and which

Rolando, I thought you reply to my April Fools Day trolling was a prank in return .... can you provide further info on the new telescope (ex design)? For it to be so light, it must be

Hi Roland, That is really cool! So is this CP4 feature limited to the 1600+encoders? (Or will the 1100+encoders do that too with the CP4?) Nice! Is there a ballpark price for this yet? -Ray

Hi all, Well we set up the 1600 mount with our new 17 inch astrograph prototype for all to see. Lots of interest for this combination. We will have more extensive information for the scope as soon as

No problem with the Taka FSQ 106 (Petzval design) I have been using for years for solar imaging. Material heats when they absorb radiation. Optical glasses are moslty

Ho Woody Not the rear elements. If you installthe wedge on a non-driven scope and not keep the sun tracking, the solarimage will drift towards focuser drawtube and other elements. TEC for

"I think this is everything. The good news is that both mounts are REALLY good - there isn't a wrong choice." You just scratched the surface. I own a Paramount for a fewyears now and your evaluation

Thanks Roland. As I saw the AP team heading to dinner tonight, I told George I would be picking his brain tomorrow for a shopping list for this. I See you have given me a parts list already so this

Just for the record, Al Nagler has stated that there is no problem using their NP scopes for solar viewing with a wedge. The rear elements are far enough forward in the light path that there is no

Pawel, I justthought of how your big scopes can heat up telescope elements -- fieldflattener. I believe the image comes to focus in the flattener -- so thatwould definitely heat the lenses up.

Pawel, I'mcurious about your comment to keep the Sun centered to prevent heating up thetelescope elements. Unless you've got a 4-element Petzvel design scopewhere the rear elements are near focus, I

Yes,it unscrews. Baader makes a special thin adapter ring that replacesit. Then you screw standard T2 accessories into thatring. Woody
