Hi! 
 
I search for photos with Night Owl 0.4x SCT Reducer Starizona with DSLR, but find only with planetary cams like ASI 290 MC. Anybody have using 0.4x Starizona with DSLR? Which are your impressions on that? 
 
Thank you very much!

The 0.4x reducer is for small sensors. Results with an APS-C size sensor are likely to be poor which is probably why not many DSLR users use it.

"Perfect correction and illumination of the image field up to 16 mm diameter."

Hi!

It says: "The backfocus distance of 38.5mm allows the use of many popular one-shot-color CMOS and CCD cameras" 

There is almost no way to use it with popular DSLR - most of them need longer backfocus - pls check flange focal distance here: https://en.wikipedia...wiki/Lens_mount

 

BR,
