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 we figure out how to use the hotel wifi setup.

Some highlights for the mount: ��encoder feedback from the shaft allows the axes to be close loop controlled to sub-arc sec levels. This counteracts wind loads on the scope and controls the position and motions of each axis to a very high precision, something that was only previously possible with direct drive mounts. In other words, you can push on the scope, as the wind would do, and the axis will push back to keep the scope pointing exactly where it was. This happens 100+ times per second, and really enhances the stability of the system. It also allows very precise positioning to 1/10 arc sec levels of both axes. This is all done in the new CP4 using the Renishaw Absolute Encoders.

We also show the new spring loaded gearbox with the ability to completely disengage the gearbox for precise balancing. The gearbox now has low wear worm gear and essentially no backlash in either axis. Tracking and guiding is now essentially perfect. For those who don't want to guide, the mount can be precisely modeled with APPC, a really sweet combination.

Mounted on the 1600 is the 17 inch F8 Astrograph. This scope is lightweight so that it takes only one person to set it on the mount. I actually placed it on the mount with no help ( and I'm a lightweight ). This is the prototype that I have been using for the last 2 years in my observatory, and we plan to make them in production this year. Quartz optics, carbon fiber, focus and forget. No cool down problems, sharp 1/10 wave optics interferometry tested. It really works, covers a 3" flat field, produced the highest resolution I have ever experienced at our observatory, even with our mediocre skies in N-Illinois.

Rolando,



Chris Go posted a seven-min video of the first day at NEAF and atabout 01:58 of the video I see the new scope. Speak about going aunaturel (not you, the new scope) and which looks like an RC design(hehehe, RC by RC).



About time seeing much greater aperture from AP after all of theseyears hassling you for the same.. (I have a C14 EdgeHD coming.. :-()

Rolando,



I thought you reply to my April Fools Day trolling was a prank inreturn .... can you provide further info on the new telescope (exdesign)? For it to be so light, it must be some sort of truss tubedesign, oui?

Hi Roland,

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

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

My apologies to the group for not posting up sooner. We had planned to post up this am shortly after NEAIC started, but the wifi on my laptop is not functioning. Very frustrating since I had planned website updates. I see that others have posted linksto a photo along with the spec sheet, so that's a good start. Roland had to resort to posting his comments from my iPad.��

Hopefully, we can post more info tomorrow.��

We have added an interest sign up on our website notification list. It will not be a chronological list like we have done in the past. It is simply a list to express interest.��

Can the spring loaded gearbox be retro-fitted on a AP900 CP3

Thanks,

Mike

#51964 Apr 8, 2016

New gearbox designs only for the Mach1, 1100, 1600. Can be retrofitted to all the older versions of these 3 mounts.

Has anything been decided on how you will retrofit older models? ��Will they need to be sent in or will you ship a kit? ��And anything about cost?

Larry, ��We have not worked out the logistics or price for upgrades. We will have more info a bit later in the year once the production 1600 boxes have been finished.
