I'm one of the two "early adopters" for Kevin's first run of the IPI-262 mount. There were some minor issues that cropped-up but Kevin was great in helping to work thru everything...This is one BIG mount; it's rated for 100# but I bet it would easily handle the same load as the AP1200.

The eq. head (RA+DEC) weighs-in at a hefty 93# (w/o counter-weight shaft), and the only thing that makes it managable is that it breaks into two ~45# parts.

Uncorrected PE with this mount is running +/- 1.5" peak-to-peak -- Following the pictures, I've included some screen shots from one of the PE data runs that I performed tonight; this data covers approx. 2 1/2 worm periods but longer runs show similar results.

Here're are a few pictures of the mount with my C8 and SV AT-1010 guide scope...

After a little work with photoshop, I was able to convert the screen capture of the PE Analysis into a jpeg so it can be displayed....

As a mount junkie, I can tell you that this sure looks like a nice piece of hardware. I hope you keep us posted about the continued performance of the mount.

Edit: You really do need to get a C14 on that thing...really!

Great mount, the uncorrected PE sounds very high end. Congratulations!

Yup, it's way too big for the C8; I had to add the AT-1010 just so I could balance the load properly. You should've seen it when I just had the little 80mm refractor on it...it was too heavy to use without the counterweight shaft installed and too light to use with it. ;)

I have a large refractor coming later this month, so that should take care of the current telescope/mount mismatch.

Cheers,
Karl

That PE isn't corrected...no PEC, no guiding, nada. Just letting the drive run while collecting data with my webcam -- The FS2 Controller supports PEC, but the data doesn't persist across power-cycles so I don't use it.

I've done 3 independent runs now to confirm the results, because I didn't believe them at first. All the runs confirmed that uncorrected PE for this mount is <+/-2" peak-to-peak...Needless to say, I'm very happy with that result. :cool:

I did mean "uncorrected", again, an impressive number. :waytogo:

Really nice setup. Those are fantastic numbers. not much to autoguide when that mount locks onto the pole.

What a beautiful beast, the performance looks better than an AP1200 really. That is a real keeper.

i would like to have this mount in the observatory and one in the living room so i could look at them all the time. the nighthawk adds a stylish elegance.

Great mount, and PE numbers. I met Kevin at NEAF. He really seems to love what he is doing. His mounts are very, very well built. If he would have been making mounts about a year ago I would have purchased one of them.
