Unable To Focus Camera O Star"Ex Guiding Module

Recommended Posts

Hello,

I'm in the process of assembling a Star'Ex spectrograph. I have a ZWO 178mm and a ZWO helical focuser. I can see the slit clearly with an eyepiece but unable to see the slit with the ZWO 178 mm camera with 2.4 micrometer pixels.

I got my Alpy 600 and measured the distance from the mirror to the ZWO178mm and it is actually less than than the length of the ZWO helical focuser. Dug up some old parts and was able to get the image. Out tonight and will try to get  some spectra.
