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.

A solar filter for my 12x DC
I had made so many of them in the past, but none of them were as elegant as this one. This one consists of the 52mm adapter, a small piece of baader film, plus a 52mm red filter. Originally, I wanted to take out the red glass but the retaining ring is too firmly attached, so I gave up, instead, I sandwiched the baader film between the red filter and the adapter.
Here's the result:
It does not look good, but it's more related to the sky condition today. And the bottomline is that, I will only use this DC (Konica Minolta Z5) for video recording.
