Weather had been terrible during the last few days. It was mostly cloudy this evening but I got a break around Jupiter. Seeing was not very good and...
Rob, Great buy. The 6" f/8 is a fairly unknown design due to its age...not over 20 years. It is, however, a fantastic blend of quality glass and relatively...
Wow! Neat, an original owner. Do you have any pics of yours you can post? Mine has "155 F/* APO" decal'ed on it. However, I talked with AP and they never...
Hi, I considering upgrading my CCD camera to something with a larger detector than the 8.7mm x 6.9mm HX916 camera that I presently use. I'm considering selling...
It has a 2.7" focuser. I was thinking a FLI PDF Focuser AP Field Flattener FLI Color Wheel FLI Proline with KAF 16803 2" on an edge I think. But is the focuser...
Louis I am using an ST-11K (24.7 x 36.0 mm chip) with my 2.7" AP155. I use the ST-11K with the FW8-L filter wheel in place which adds a little to the ...

Hi Larry, I have the same scope and just got an Apogee U16M. I haven't used it yet since there are no filter wheels available yet that won't vignet. Apogee...
It was mostly cloudy again today. But it was clear around Jupiter's position. Conditions started bad but improved as Jupiter got higher. The GRS is very...
... Roland: where exactly is that info? I have an STL-11000 with the FW8-STL and I think the Robofocus is having a little trouble at times with that, the FF,...
Roland, Thanks for the helpful advice and feedback. I'll continue to puzzle over the camera and filter wheel choices and then figure out how to bolt all this...
I currently have an AP130EDT and 27TVPH. I understand that if I move to a big-chip CCD (e.g. STL11000) then i'll need to use the 67PF582 field flattener, but...
Thanks, Gilles, I suspected that might be the case. The 27TVPH is useful because it's easier to guide my 'not very good' G11 at the shorter focal length....
Dave FWIW I use RoboFocus on my AP155 2.7" R & P focuser. It carries an ST-11000M+FW8-L attached to either the AP Field Flattener or the Telecompressor. The AP...
Hi Ben, I'm afraid it is one or the other. You would not be able to achieve the correct spacing between the field flattener and the CCD chip with the 27TVPH...
Condition wasn't very good this evening. I was forced to image early because of clouds! but I have no regrets! The SEBs in a mess. The outbreak has really...

Hello Louis, The coupler you refer to is part of the RoboFocus and should have come with it. It is not part of the bracket. Mag. 7 skies! Howard Hedlund ...
I have one of these scopes also. I've been very pleased with the optical performance and have considered doing some CCD imaging with the scope. Does anyone...
Hi Louis: I can't help on many of the scope specific questions, however, I can tell you I am incredibly pleased with my FLI Proline 16803. It's been absolutely...
In a message dated 7/3/2007 1:39:23 PM Central Daylight Time, ... You can use the 130F8/155F7 field flattener. You can also try the 0.75x telecompressor. It...
Rolando, I have AP's 0.67-0.75 CCD telecompressor, if that's what you're referring to? The largest chip I'll be using for a while will be the Starlight Xpress...
In a message dated 7/3/2007 6:56:13 PM Central Daylight Time, ... I have used the 0.75x 2.7 inch telecompressor with my 160F7.5 to cover an STL11K chip. The...
In a message dated 7/3/2007 6:56:13 PM Central Daylight Time, ... The .67x CCD telecompressor will not cover a large size chip because of the limited size of...
Yes, the scope has the 2.7 inch inside diameter focuser tube. I guess i was mistakenly under the impression that the 0.75x and 0.67x magnification compression...
Awesome shot Roland! So I need to order this 0.75 TC. I checked your website just now. It is a different part than the the CCD67 TC I own. I can still use the...
