20171117 Sun

Seeing bad, transparency 4/10.


0617 (UT), there might be a small active region forming at the right near the center, but the most interesting feature is the filament at the 3 O'clock position and it extends beyond the solar disc as a prominence.  Not very big, however.

Cloud moving around, the AVI was not stackable.

Only a very subtle filament available visually.

Just a record.

20171030 Moon

Same poor seeing, and even worst since it's even cloudy.  I've to wait until I can capture a few very short clips.

C5 with 2x barlows.

1418 and 1427 UT:-



Just for fun (no fun indeed)

Tele Vue Ranger with JMI focuser

Solarmax 60 II with BF10

ASI 120mm

Reducer lens (binocular objective) fitted into the barrel of the BF10


0647 (UT) for the above full disc shot, 0652 (UT) with a 3x barlows after the reducer lens:


Very poor seeing today, I would rate 2-3/10.

20171026 Moon

I pulled out my C5 tonight to test my DIY focusing motor, seeing very bad at 3/10, transparency 6/10.

First up is a prime focus shot, taken at 1159 UT.


Next two are taken with a 3x barlows, taken at 1203 and 1208 UT respectively, 70% resized to hide some of the bad seeing.



Collimation could be better, since I didn't even tweak it before imaging.

The focuser is fine enough and it helps a lot at high image scale with my shaky Nexstar mount.

20171006 Sun

Seeing still no good, but less cloudy today.

0549 (UT), I messed up the RichView and Tmax apparently.


Next is a close up, this time I used added a 3x to the above setup without removing the reducer, I found the 3x parfocal with this configuration, so I would probably use it more often!

0552 (UT), two styles of false color.



No preference for myself, but it seems like the inverted one is more popular these days.

A simple followup AR2683.

20171005 Sun

Very cloudy today, seeing unstable as well.

First one is taken at 0542 (UT), two ways of processing, false color anyway.



Finally, a close up of AR2683 with 5x powermate:-


lack of detail indeed.
