Wow.. thats nicely executed. And the price is right considering the MEF.

How about one for the 4" focusers? e.g. the FSQ?

Fwiw, the MEF is ok. I had mine slip on the shaft, and had to re-tighten it last night.
Good thing someone had tools. I also think the torque-arm/bracket needs to be beefier.

Is this for real?

Here's a recent M42 from the SF bay area....

This was done with a camera I modified using a
8" f4 Meade Schmidt-Newt and guided w/ a DSI-Pro.

A IDAS-LPS was used to cut down on the sky glow.

Here's a recent m42 using a filter-less 300D on an 8" schmidt newt...

(coma in the SN is a bit annoying.)

Assume the following...
- TOA 130 OTA now (and C14 later)
- 90% imaging and 10% visual
- 90% traveling-to-dark-sky-site, 10% backyard narrowband imaging.

Which mount would you prefer: ap900 or ap1200?

Why?

thanks

tell them you need a photo of the telescope w/ today's newspaper showing the date.

I use two clamshells and mounted losmandy dovetail adapters to the top of them.
Then I mount a losmandy DUP to the dovetails. This carries the guide scope.
(My current guidescope has losmandy rings mounted directly to a DUP which then
fits to the DAs. Fwiw, I think a better setup is to just mount another
dovetail saddle to the top of the clamshells.)

Here's the setup... Note that I took out the existing bolts and used
new 1/4-20s.



and... here's ways I've had the guidescope mounted to the DAs...

With the guide camera mounted on the DAs using another
pair of DAs on losmandy rings; there's a losmandy male-male between
the imaging OTA and the guide scope...


Here's another picture with a 80mm f11 guidescope bolted directly
to the losmandy DUP.
