Welcome to my astronomy blog. I dedicate myself to the simplest form of amateur astronomy which requires only portable equipments. I have small refractors, small binoculars, a small 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.

Not bad I would say.
The circular pattern belongs to the focuser, and the OTA is the black lined cloth/paper like that of the Ranger: light weight, simple and effective as you could see from above.
