It’s a wide angle lens, for all-sky preview and check the camera. It’s nothing to do with planetary imaging.

this is CS lens
CS is standard interface
so if you camera have CS mount, you can mount it

Ian – :
Oh I forgot to mention I also have a zwo1600mm-c, so if any of your lens can fit on to that and still fit inside the draw tube that would be great, keep it in the family

Sam Wen – :
this lens is only for 1/3″ sensor, 1600’s sensor is too big

Ian Price – :
Does this have a C or CS thread on the back of it?
I’m interested in using it with my guide cam to inspect my primary & secondary mirror alignment. Guide cam isn’t from zwo
but has a C thread adaptor with I think 17.5mm back focus. I also have a low profile 2-1.25″ adaptor so it should fit in the draw tube even if the lens and focus knob is wider than 1.25″
