I am quite new to the whole astrophotography thing, and have put together a fairly sophisticated system that I am perhaps a little under-skilled to use properly. It's been a few months since I had a chance to use my gear, since our Southern Hemisphere summer meant short nights and clouds. But the conditions were good this past week, so I trotted the gear out again and set to capturing some narrowband images.
All was going well, it seemed, until we had a meridian flip, after which the guiding went all haywire, with the Asiair telling me that it timed out waiting for the guidescope to "settle". I had fairly steady declination but the RA was off the charts and the resulting images were unusable. I paused things, and after trying a few things, I ended up aiming the telescope at a new target and starting with a new plan. These shots were fine, and guiding remained pretty good through the rest of the evening.
The next night, I tried to shoot again, and this time the guiding was fine through the Ha and Oiii filters, but when it came to Sii it again went off the rails. This has not happened before, so I don't know if it's something I'm doing wrong, or if it's something with the latest update to the Asiair (1.9). Anyone have any ideas?
UPDATE: Following the response below, I have checked my imaging train and the OAG is indeed in front of the filter wheel, so there should be no connection between the filter and the guiding.
