Got this new and remarkable lens. Astounding to be able to buy a brand new 135mm lens for less than $900 that performs near perfectly at f2. At first I thought something was wrong as on live view the stars seemed very faint. But it was because they are so tiny.
I used the duo narrowband clip filter in the Ra camera as its too light polluted unfiltered here. At a dark site this lens unfiltered would be magnificent.
Shot Orion wide field, 30 x 2 mins iso 1600 and 2 x iso 100 for the core of M42. Full size here. https://www.astrobin.com/j04o0d/
Had a crack at the Dolphin Head Nebula widefield. 13 x 5 mins iso 3200. I could see the Dolphin on the unprocessed subs!

Both shot with lens wide open.
