Do we need an IR filter with this lens to get real color of the sky ?
Which one ?
I would like to use it with 224 MC.

  Sorry you can’t use IR filter when this lens was instaled in the camera. And we don’t have a solution, you could do it by yourself.

Can you support it as an additional image channel in ASAI Pro? Would be very useful for remote application to have a look to the sky (clouds etc)?

Can I use this lens on asi183mc color? if not, can you recommend a fisheye lens for asi183mc color? Thanks a lot!

  183 sensor is too big for fisheye lens.

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

I never got one with my ASI290MM-cool. But I did get one with my ASI120mm, would it still work with the cooled version?

  this is CS lens and won’t work on our cooled cameras
  you need C lens to work with cooled cameras

minimum focus distance this lens can achieve when properly mounted to a 1/3″ sensor eyepiece camera with the correct spacing?

Thanks

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

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

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

Ian Price – May 22, 2017:

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″

  yes, this is CS lens, you need 5mm extender to use it on C mount camera
