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.

20171002 Sun

The sky is mostly covered, but we have some gaps.

Seeing 4/10, transparency 7/10.

Full disc shot taken with reducer at 0559 (UT):-


Long time no making mosaic, so it's kind of failed, anyway.

Taken at 0603 (UT) 0605 (UT) 0606 (UT) 3 frames mosaic of AR2682 and AR2683.


Ranger with 3x barlows (reducer removed), Solarmax 60 with BF10, ASI 120mm.

20170928 Moon again and again

This time, I pulled out my DIY modified Canon FD 300mm f2.8 lens.


Taken at 1307 (UT), at prime focus for this full disc shots.

Before taking this one, I took two shots with a 5x Powermate:


1300 (UT)


1302 (UT)

Quite nice actually, the contrast is much improved already.  Focusing is a bit hard with my shaky Nexstar mount with the built-in helical focuser.

20170927 Moon again

Again the moon was still low in the sky when I finished my dinner.

Anyway...


1232 (UT), Ranger at 3x, ASI 120mm.
Maybe I shall try my Canon FD 300mm f2.8 tomorrow night.

I have to use two extension tubes since I skipped the diagonal unlike last night.

20170926 Moon

Accidentally saw the moon outside the window, sinking rather low in the sky.  Pulled out my Ranger to have these two shots, very poor seeing and low transparency.

1243 (UT), Ranger at prime focus:-


1247 (UT), Ranger with 3x:-

20170911 Sun

I was reading books on my holiday but then I suddenly realized that I didn't do solar imaging for quite some time, so why not?


0714 (UT), taken with my Ranger, Solarmax 60/BF10 plus a small reducer lens dropped into the barrel of the BF10 as usual. 

ASI 120mm with my new N4200 laptop featuring a 128G SSD, my Teclast formally retired after the death of its bluetooth module, I could no longer use a mouse now, and that makes Sharpcap very hard to use.
