recceranger Posted October 7, 2020 Share Posted October 7, 2020 (edited) Hi folks, I recently got hold of the new ZWO ASI 462MC Colour Imaging Camera and was testing it on Mars with my RC8 a few nights back. The RC8 focal length is 1600mm and I wanted to add my Baader 2.25x Barlow (for Zoom Hyperion) to the camera but when I did it was a complete image blackout!. To ensure the image didn't simply shift out of FoV at increased mag, I zeroed in on the centre of the moon but still a blackout. I'm all ready using all of the supplied iOptron RC8 extension tubes to achieve the required back focus. Any advice is greatly appreciated.
