Do you have a exemple of spectre with this configuration (APN) ?

thank you
Sébastien
Sorry no. I only used this configuration with a DSLR once once to see if it would work. Spectroscopy is much easier with a mono astro camera

Cheers
Robin

Hello Robin,

I also have an Atik314+ but i don't have an adapter to connect the camera to the objectif photo 50 mm.

what's your adapter ?

I used many adapters from my junk box screwed together together to convert an Olympus lens to T2.

You can do it much easier though using this adapter

plus an adapter of the right length to reduce to 42mm from the list there

Cheers

I do not know but you can calculate it (camera lens to M48 + M48 to T2 + atk 314 back focus = back focus of the camera lens) or you can ask Teleskop Service
