Description

First light for the TAIR-3-PhS 300mm F/4.5, vintage Russian lens for Zenit SLR camera. The lens is supported by the ZWO EAF attached thanks to my own 3D printed adapter. HFR=1.58 by the Astroberry/Ekos and its linear algorithm.

Unbelievably flat field and significant CA appearing as red rings around stars. Attempts to remove them took me 4 days, but I'm happy with the result.

This is a fast lens, but using the Optolong L-eXtreme filter causes the picture to be quite dark at the end. I think it would be great portable setup for dark sky far away from LIverpool and no filter.

In general, I'm happy, because I bought the lens for £60, so together with the EAF it cost less than £300.
