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.

Yep. Fully manual focus so not so good for sport or bird photography but my goodness the optical quality for the price is great. Apologies for any cloud the purchase of any new astro gear seems to bring.

Yeah it's a great lens if you get a good copy.
