You've got some lovely single sub images Mike. Very reminiscent of your film work, only quicker. Having said that I watched you set these up and you take great care ( Read loads of time ) setting up each exposure

Do you find you can't open up any more than f7 ? Seems so slow. How are the stars at f5.6 ?

I always shot at f8 using film so f7 offered a similar reference point for me as a comparison...f8 would offer little advantage over f7.

As I now know the maximum sub time for the 60Da under similar conditions & settings I will now shoot at f5.6 for optimum sub time with hopefully less noise...the stars look ok at f5.6.

Right, got you.

It will be interesting to see how far you can push things.

Lovely colors!

Thank you.

Dave

Will try to push as far as possible with an ʹoff the shelf` 60Da but the sky conditions will always be the biggest factor in the results as we all know but do enjoy a challenge!

Just need some flats, darks & a few more coats of astro-paint! ;¬)

This is cracking Mike, was it from the Friday night?

Did you use an EQ type mount or an Astrotrac?
