I would very much like to add one of these to my astro-arsenal! I have a 183mm Pro and a 120MM. Is there a way, even if adapters are necessary, to mount either one of these to my cams for some wide angle shots.?

Hi, sorry to send another question, but just to make it clear
With an ASI224 and this lens at 12mm, will I be able to take long exposure photos and capture nebulae?

Sorry this camera is very suitable for meteor capturing as the description mentioned. And it has a wide field that nebula looks very small.

Hi Sam, I got a 290mc which came with the 2.1mm lens I believe. But that lens has no uv/ir filter built in, and apparently I can’t add one (insufficient back focus). Does this lens have an ir/cut filter built in? If not, is it possible for me to add one (I have a 1.25″ uv/ir filter)? Thanks in advance

Katherine Tsai – :
It does not, you can replace the protective window with UV/IR cut filter.

Charles – :
Hi, many questions…
This should work on an ASI290MINI with a CS adapter, right?
Can you tell me the dimensions of the lens, especially diameter?
Also, I see 3 controls: focus, zoom, and what is “O – C”? Iris control?
Can you tell me the closest focus distance at maximum zoom?
Thanks!

JM – :
Could the lens be used on a 174 sensor on low resolution mode? For example, in 640×480 I imagine that the effective sensor area is around 1/2.4″, so the lens should be able to illuminate most of the image area. Is that right? Would the back focus and dimensions fit for the 174MM or 174MC models?
1
0
Sean Wang – :
Yes, you are correct, ROI will reduce effecitve area. 174mm and 174mc have 17.5mm back focus for C mount lens using our CS-T2 mount adatper(because of the back focus of 174, the cs mount only can use a C mount lens)

Peter – :
Will it work on a cool cam using a 5 mm spacer? I can’t find a c-mount lens on the site, they all seem to be cs-mount.

Sam Wen – :
no, CS lens cannot work on C mount
but C lens can work on CS mount with the 5mm spacer

only C lens can be used
