paul Posted April 18, 2021 Share Posted April 18, 2021 I've had easy success using a ZWO EAF on my refractor, but the results I am getting with an EAF on my 150mm newt are disappointing so far with double diffraction spikes resulting. I've tried APT and NINA. Rather than investigate further with tweaking parameters I revert to the bhatinov mask, but I would like to automate it as I need some sleep for work.🙂 I'm finding that during the night the focus moves off from its sharpest and I would like APT or NINA to tweak it periodically. I've searched for tips and apart from people commenting on how the central obstruction can confuse the process (doughnut holes make it difficult) I don't see anyone stating they have it working. I suspect I need to improve my estimate of backlash, but it would be good to hear other people experience before I waste my time! Can anyone offer tips or a focusing package that they know works? (FYI I'm using the latest ZWO 7 filter set and I don't see significant filter offsets on the newt at all.) Quote Link to comment Share on other sites More sharing options...
