How do you power and access two CCDs? I dont want to power both since I will use one at a time. Yanzhe

Thanks, I'll check it out Yanzhe

Yes, Imaging. When you say both can work, are you talking about "piggy back" and "side by side"? How about power supply and USB? Each will have its own OAG to eliminate flexure. Yanzhe

Reposting from a few months ago: I posted this long ago when I was using a 1200 as a “portable” mount. Since then I have a 1600 mount in an observatory. But I recently received the very

Brian, I do understand that, but although I leave the mount on the pier in the backyard, I do not leave the OTA there. For safe carrying, I have a D plate handle assembly; to use it I remove the

Roland, Thanks for the excellent explanation of what happens. That would explain, I believe, the appearance of large RA spikes literally out of nowhere. It would seem that the bearing

>>>other than indicating that I don't always have the axis of the guide camera aligned with the axis of the mount movement. I typically try to adjust/make it perpendicular on the next calibration.

Ortho looked good, always has with this mount - other than indicating that I don't always have the axis of the guide camera aligned with the axis of the mount movement. I typically try to adjust/make

Yanzhe There was a short thread on the dual scope topic back in March. In fact, it was specific to the 1100, so you may find useful info at https://ap-gto.groups.io/g/main/topic/81188350#76876 Bryan

I have an 80mm piggybacked on top of my C11" on my AP1100. Cameras on both with filter wheels and auto-focusers 7 USB ports. I use to guide the 80mm with the OAG on the C11 and that works most of

By 'one at a time", are you referring to imaging? Either way can work, I've done both. The biggest issue will be the possibility of flexure between components depending on how you will be guiding. If

Have been thinking of setting up two scopes (4" and 5") on AP1100, only 1 scope will be used at any time. A few questions on exactly how it should be configured/connected. - Piggy back vs side by

thank you everyone. I need to be quicker in setting up the rig: my last night out was in November and this doesn't allow me to build a routine... in the future I'd like to run a small model before

Typically, crosstalk occurs when the Dec axis is moved slightly during guiding, and this causes a corresponding Ra movement. It typically happens when the scope is pointed toward the meridian

Hi Clayton >>>I'm trying to get some idea/context for the issue of DEC crosstalk to the RA axis during tracking/guiding. How does the orthagonality of your guiding calibration look? if it's not at 90

I have never seen it in any of our present mounts. It can happen if the Dec main bearings are not fully pre-loaded. Rolando

I'm trying to get some idea/context for the issue of DEC crosstalk to the RA axis during tracking/guiding. I see this as a topic that seems to come with different users in the Paramount forums almost

Hi John, I also have an AP 1100. I have two shafts because with a smaller scope I have to use the shorter shaft. Either way I purchased a zippered carrying case designed for a tripod . I don’t

A long time ago, way back when traveling to star parties & favorite dark sky sites was a normal routine <clearly prior to being locked up & boarded up thanks to the pandemic> I used a metallic tool

I have the 1100 shaft with extension. I used to carry it in my counter weight box, but now that is too heavy for this old guy. So I keep the shafts in a length of white plastic pluming pipe. I added
