After a long hiatus with no sunspots, there is one at last.
Battling against a lot of cloud, I managed to get a few seconds of precious video in (about the only) clear spot there was and processed it to get the image below.
The photo suggests that my Quark is not quite flat to the image plain – I am not sure if this is the focuser or the Quark etalon itself – I do have a tilt adapter but today was set to 0 degrees.
Can anyone tell me which from the photo?
