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. :-)

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!

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...

Here is one of the formula for planetary imager:
Clouds + Fog + sleepy = Lousy Image.
Anyway still some details can be captured. :-)
Awaiting clear skies!
