ASI cooled cameras "parfocal" in the future?

olav

Hi there,

I think I'll order a 174MM and wonder if I should choose the cooled version.

It will be mostly for moon/solar use, and maybe some autoguider duty.

Then, it would be nice to interchange with my ASI1600s for some DSOs at long FL, from time to time.

Just taking out one camera from the EFW and insert the other.

But the 1600 has 6.5mm backfocus, while the 174 takes 17,5mm (plus adapter).

And I can't just add some extension between the EFW and the 1600 to match the 174 BF, my setups are currently perfect and there's no extra BF in the imaging train.

I'm mostly curious; is there some roadmap for matching the small-chip ASI bodies in the future?

Well I like the 17.5mm backfocus, my 174MC Cool has it as well my SXV-694.

Even ASI 1600 has it (with the removable M42 extender).

6.5mm backfocus is nice to have if you are going to use fw with camera lenses.
