I used a autofocus routine. In Backyard EOS it would be pure manuel. 

apt can autofocus ,never got that far as mount went off for a service and belt mod

I tried Maxlm, SGP and Backyard EOS just using the jog buttons, far more sensitive than a Manuel adjustment

That's very nice. 👍

 

You have double star M40 in there and "La Superba" the deep red variable star just left of bottom centre.

Megrez, the middle and faintest of the seven stars, looks quite dim. I found some vague internet references saying that others think it is actually dimming and one stating it has dimmed since ancient records over 2000 years ago. I remember older astronomers in the 1970's saying it had dimmed during their lifetime in comparison to the other main stars. I checked in an old book of mine published in 1967 which listed it at mag 3.4 which is not much different to most recent references that list it as mag 3.3. 

 

Has anyone else thought this, or have any magnitude details from older books?

Nice image Alec 👏

 

I'm interested in your thoughts on Affinity Photo. Are you using it on a MAC platform i take it ??

How does it perform from an astrophotography point of view ??

 

Pete : i have it listed as Magnitude +3.3 and i often find it visually quite difficult to even see

from home (Derby, light pollution central) That shows you how bad my local conditions are, or is it my rapidly deteriorating eyesight as well i wonder...!!!??? 😀

I think its a lovely constellation : i always refer to it simply as 'The Saucepan'

And i never miss the opportunity to have a quick look at Alcor and Mizar, which to me,

is one of the nicest doubles in the sky.

I'm running it on windows 10. So far I'm finding it quite easy to use, searching on the internet finds a lot of similar functions as in photoshop, and all of the adobe plugins work with affinity as well. It has a stack facility which is quite good to use. If you dont want to fork out wads of cash on Photoshop its a good alternative.
