m81

Hi everyone

I was gonna entitle this 'm81 and not m82'.

More experimentation with binning, I didn't think it would work for galaxies -contrast and stuff- but it does. The noise reduction is surprisingly good, perfect for those of us who cannot leave the telescope be during sessions...

Thanks for looking. Any comments especially on binning galaxy shots, as always, most welcome.

Looks good to me. Which scope did you use?

Hi, no. It's this one with the aluminium alloy tube.
