AP 900 CP2 vs. CP3 new
      #5658497 - 02/02/13 04:53 PM

Hi,
Considering to buy used AP 900 CP2 GTO mount. But can not find any info about it. There is only CP3 manual on AP website.
Can you tell me the differences please?

Linking into the AP website is a pain.

Go here:
http://www.astro-physics.com/index.htm?products/mounts/servodrive/servodrive

Ctrl-F Search for
"The GTOCP3 can be purchased as an upgrade"
and follow the link, which describes the CP3 additions.

Aww, I have been blind. Found it. But one thing is still not clear. Is there permanent periodic error correction available with CP2? Or I will have to record it every time?

It is permanent. It just needs to be trained using the autoguider input, if I understand Ray correctly. Meaning there is no "direct upload" mode.

That said, direct upload is just as slow as using the AG input because there are almost 1000 PEC cells.

Did you nab the $5100 AP900GTO-CP2 on the mart? best deal I've seen ever.

The CP3 controller itself can be bought for $1000.

Thank You very much Orlyandico for short and detailed explanation. The mount I am considering is in Europe, me also, and for much more money. As everything made in US cost twice here unfortunately.

did you see the 3000 EUR Gemini G41 being sold on the mart? 3500 including Pulsar controller but no handset. ad# 807848

Might also be an option. I know if I had seen that G41 ad before I got my Mach1, I would have seriously considered it.
