Hi, I am pretty new to solar photography so please excuse a newbie question. During the recent eclipse I was shooting with my Solarmax 90mm and ZWO174 and it is usually very straight forward to find and focus on the sun. During the ecplise I had a lot of issues with solar flares and weird "mirages" when trying to find the sun. When I found what I thought was the sun (including the shadow of the moon) I was not able to find focus (on the 90mm I usually have to extend it fully + extend the camera a bit more to find focus, now to find the closest i could to focus I had to retract the full tube quite a lot) + it was much dimmer than usual and I had to push the gain to over 300 (usually have it at 0-30 for 10ms exposures)
After giving up on finding focus I started to move the telescope around a lot and found the real sun, and all was back to normal
Any ideas of what was going on?
