Product QuestionsIs the Slimline OAG compatible with the Orion Starshoot Autoguider, or will I need a C-thread to T-thread adapter?Question by: JD on Jul 17, 2015 9:01:00 PMYou would need a low profile female C-thread to male T-thread adapter to attach the Starshoot Autoguider or other T-thread camera to this OAG. The Starshoot Autoguider has a slightly longer back focus to the Starlight Xpress guiders, so you may need to adjust the guide camera height inward slightly depending on your camera configuration.Answer by: Chris Hendren (Admin) on Jul 20, 2015 11:44:00 AMHello,
I purchased this OAG and can't get it to focus with a SSAG Pro Mono. This guider is a bullet style that look like the QHY5L II. Do I need an extension tube? The camera screws in to the OAG fine but w/n focus in PHD. ThanksQuestion by: Mike Rogers on Jan 11, 2016 7:08:00 PMThe SSAG Pro Mono is a C mount camera with a back focus of 17.5mm. The Lodestar, which this OAG was designed for - is a CS mount camera with a back focus of 12.5mm, meaning the sensor in the SSAG Pro is 5mm too far from the CCD. If you can't loosen the setscrews and move the camera closer to the prism in the OAG, you will need to add a ~5mm spacer between the OAG and your imaging camera to make up the difference.Answer by: Chris Hendren (Admin) on Jan 18, 2016 6:48:00 PM
