20170808 Partial lunar eclipse

I am cleaning up my hard driver to the cloud, and so I posted them here first.

I didn't go out for observing, I slept as usual but with an alarm clock set.  I woke up, didn't open the glass window and shoot through hand held with my Canon 100-400mm.  So, just a record.

First one is a short brief moment when the cloud cleared up:


And the second one which was the usual condition of that night.


Finally, an overexposed shot in the hope to light up the dark side.


And then go to sleep again.

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.
