I also did something last week so I could still focus because I do every thing from inside my Wed, 02 Dec 2009 11:37:49 GMT Robert Brian Brown http://tech.groups.yahoo.com/group/autoguiding/message/6452 http://tech.groups.yahoo.com/group/autoguiding/message/6452 I have had very similar problems, unable to get focus in the side turret. The images are blurred and its gets better when getting the prism closer in, but I Wed, 02 Dec 2009 10:14:30 GMT William Hamblen http://tech.groups.yahoo.com/group/autoguiding/message/6451 http://tech.groups.yahoo.com/group/autoguiding/message/6451 He said that he had to pull the prism away from the center line to focus the guide camera, which implied that he had to increase the distance from the guide Wed, 02 Dec 2009 07:54:51 GMT dunmunro1 http://tech.groups.yahoo.com/group/autoguiding/message/6450 http://tech.groups.yahoo.com/group/autoguiding/message/6450 Wasn't the FR designed for use with a SLR/DSLR? If so then the distance to the focal plane of the imaging camera should be at least 42mm, which presumably is Wed, 02 Dec 2009 07:29:31 GMT bakersfieldbiker http://tech.groups.yahoo.com/group/autoguiding/message/6449 http://tech.groups.yahoo.com/group/autoguiding/message/6449 Hi Duncan, Here is a photo of the camera, wheel, OAG and reducer. Is that what you wanted to see?

It would require closer to 10mm to get the prism in far enough to get into Wed, 02 Dec 2009 06:20:31 GMT dunmunro1 http://tech.groups.yahoo.com/group/autoguiding/message/6447 http://tech.groups.yahoo.com/group/autoguiding/message/6447 Can't you could increase the distance of the imaging camera from the OAG by a few MM? This would allow the prism to move further into the light path. cheers Wed, 02 Dec 2009 05:50:13 GMT dunmunro1 http://tech.groups.yahoo.com/group/autoguiding/message/6446 http://tech.groups.yahoo.com/group/autoguiding/message/6446 Can you post an image of your setup? cheers Duncan Wed, 02 Dec 2009 05:03:49 GMT bakersfieldbiker http://tech.groups.yahoo.com/group/autoguiding/message/6445 http://tech.groups.yahoo.com/group/autoguiding/message/6445 Hi Bud, The distance from the prism to the guide Chip must be equal to the distance from the prism to the imaging CCD Chip. Otherwise you will not achieve Wed, 02 Dec 2009 05:00:02 GMT bakersfieldbiker http://tech.groups.yahoo.com/group/autoguiding/message/6444 http://tech.groups.yahoo.com/group/autoguiding/message/6444 Hi Duncan, You move the cap of the stem with the camera mounting plate up and down the stem to get focus, then tighten a set screw. So as you move it down to Wed, 02 Dec 2009 04:12:18 GMT William Hamblen http://tech.groups.yahoo.com/group/autoguiding/message/6443 http://tech.groups.yahoo.com/group/autoguiding/message/6443 ... Can you put an extension between the autoguide camera and the off axis guider in order to put the pickoff prism farther into the light cone?

I went out last night to do testing with the APM TS OAG. I used this unit due to its thin design of 9mm, which I needed to be able to use my TV reducer and Tue, 01 Dec 2009 23:56:43 GMT bakersfieldbiker http://tech.groups.yahoo.com/group/autoguiding/message/6440 http://tech.groups.yahoo.com/group/autoguiding/message/6440 Hi Olivier, I will psot later in more detail, but for now I will just say the APM TS OAG did not work for me. I am not sure that I will be able to use an OAG Tue, 01 Dec 2009 01:25:49 GMT olivierfp http://tech.groups.yahoo.com/group/autoguiding/message/6439 http://tech.groups.yahoo.com/group/autoguiding/message/6439 Hello Floyd, So what OAG did you settle on and how is working for you?
