Dear friends,
No imaging for more
than 2 months already. Finally I completed the new setup of a 10"
Newtonian at my roof. :-) Last night has fixed the balancing problem of the newtonian and polar aligned the
scope (no polar star can be seen at my site). Finally still
got time to have a few test shots. :-) The Royce mirror has been
recoated and the reflectivity was so much improved!!!
Attached were two
Jupiter images captured last night, seeing was fair and transparency was
terribly low. heheh. As long
time no imaging/processing, I totally forgot my processing routine already.
Have to spend a bit time to recall them. Anyway, my imaging session is resumed
already.

heheh.
You may be interested to take a look how I solve the balancing problem with the
"unknown" metal clamps on the door handle. :-)

Dear friends,
Attached Jupiter shots
were captured tonight. Transparency was very bad again. This time I used F34 to
achieve higher focal ratio though the gain set to 70%.

I am sure the image
quality can be improved if the transparency can be better!
Kind Regards,

Dear all,
Attached was the
Jupiter captured last night. Cloudy before mid night, so could not get decent
images when Jupiter at zenith position. I must say that the sky condition was
far from last year ... Probably due to severe air pollutant blew from Mainland
China industrial area ... Now seldom get a night with high transparency and
stable seeing...

Dear friends,
Here is one of the formula for planetary imager:
Clouds + Fog + sleepy = Lousy Image.
Anyway still some
details can be captured. :-)
