MartinS Posted February 26, 2021 Share Posted February 26, 2021 While still learning Pixinsight, I can now at least complete most of the basic functions. Complex tasks are still beyond my ability at this stage, but hope to get some steers or guidance from other members. The corners suggest the Back Focus distance needs to be extended and so far I have tried up to an additional 5mm beyond the recommended focuser distance to no avail. Now I suspect the Flatteners flat field is rolling off the edges of the APS-C sensors real estate, any thoughts. Feedback welcomed. 7 Quote Link to comment Share on other sites More sharing options...
