Quick test of Tair 3S lens

[riklaunim]

I finally was able to test Tair 3S M42 lens. I still need a proper mounting to balance it on the telescope, but at least it works properly. It has 300mm of focal length at f/4.5 and is quite heavy. It's also quite popular among M42 lenses for astrophotography (good corrected field).

Here is a 100x15s H-alpha Atik 314L+ test shot:
