anti-reflective internal treatment Celestron C5 (1 Viewer)

[stefano.sec]

Hello everybody. I use a Celestron C5 for daytime observation and I wanted to try to improve the antireflection of the tube trying not to do any damage. I have not taken many photos but for those interested, here I have made a brief description.

Good to hear it made some improvements.

I saw a similar modification, but lining the drawtube carefully.

This was effective.

It was maybe a YouTube video and a Celestron 90, of which there are several versions.

There are some scopes that use this method from new.

Regards,
