reprocessed jupiter - 23rd Feb 1625UT

Posted By Tan Wei Leong
Dear everyone,

The skies is cloudy and I've no new mars images so I dig out some old jupiter image and reprocessed them.

I feel the reprocessed is much lesser noise and looks more natural.

Here's the reprocessed version.

and the original version.

Stack of about 1000 frames out of 1800.

Dear friends,

Here's the mars image from 8th July 2003.

Seeing is a little poorer compared to the 6th July and I managed only 1 image.

mars image 15th July 2003 1941UT

Posted By Tan Wei Leong
Dear Friends,

The skies weather here has been cloudy most of the time for this month and this morning I managed to steal a few minutes when a small clearing occurs thru the clouds which allows me to image for about 30mins.

Seeing was 5-7/10 and transparency 4-7/10 (thin high clouds)

As usual the images are done with the 250mm Takahashi mewlon @ f/67.5 with the Televue 5x powermate + Philips Toucam Pro and the Baader UV-IR blocking filter. I've experimented with a combination of televue 2x+1.8x barlow for a lower F ratio in the region of f50 which I will process the AVI and send them out this evening.

Best Regards

Dear friends,

This is another mars image from 15th July 2003 at 1959UT.

Damian peach is kind enough to process it for me.

I think this strikes a balance between details and "natural look"

mars image 15th July 2003 - super natural version

Posted By Tan Wei Leong
Dear friends,

This is the "super natural" version of the 1959UT image.

I've tried my best to make little processing to it.

mars images 22nd August 2003

Posted By Tan Wei Leong
Dear everyone,

Here's the mars image from 22nd August 2003. Mars has reached 25" and 5 more days to max size.

This is also my first image using the 40cm pentax cassegrain at the Singapore Science Center Observatory.

Please note the limb haze as well as clouds over sytris major.

Special thanks to those that help me back with my "feeling" during processing. The beauty of astronomy is such that we all share what we have with the rest.
