20170821 Sun

Didn't play H-alpha solar imaging for quite a long time.  A typhoon is coming and the air is extremely dirty, cloud were floating around and thus the imaging window is short, I couldn't even take a full 900 frames AVI.

Just a record:


0710 (UT), at the center is AR2671.

Taken with my Ranger, Solarmax 60 with BF10, ASI 120mm with a reducer lens in the BF10.

After this imaging session, I've removed the encoder assembly from my JMI DRO focuser, it's just too bulky and I don't need to DRO for solar imaging at all.  Anyone interested in that assembly with the hand controller can contact me.
