Welcome to my astronomy blog, I dedicate myself to the simplest form of amateur astronomy which requires only portable equipment. I have two small refractors, two small binoculars, one small GOTO mount and another small equatorial mount, and a small H-alpha solar filter.
Originally from a city where the people were proud of their light pollution, that is Hong Kong where I loved. Relocated to the UK since 2021.

20250117 Jupiter again
Spent more than half an hour to fine tune the collimation, found something strange on the out of focus pattern.
That irregularity on the 6 O' Clock location.
I captured 60s worth of frames this time, instead of 1000 frames.
