Will you use a reducer on the 76DS?
Hi Tony,

Nice images, My Helix I could only get 60sec with sought of round stars. UV/IR filter only.

I do have a reducer never used it as I need some more connection bits to the camera.
My problem is getting a good enough polar alignment (no pole visible large tree not mine )for long subs max 60 -90sec on a good day and i haven't tried guiding yet either.

Here's one of NGC253 Sculptor Galaxy
