Hi Sean

Thanks for sharing your findings on the Edge, sounds like the focus locks will be adequate for intended subs.

Keep up the good work on those longer focal length targets! 😉

Hi Sean

Thanks for input, sorry for delay in reply.

So i'm assuming the mirror locks on the edge do a pretty good job of avoiding mirror flop, if so approx. how long a exposure might you get before your stars become egg shaped at F10.

I would only be needing 5min max. ....but 3mins (give or take 1min) would be adequate unguided.

Your input appreciated!

Mike

Well done Sean those are both very good results and testament also to just how good the Edge optics are... even toying with the idea of getting one myself.

On axis guiding is another option...  assuming you were Off Axis Guiding are you using the Atik OAG or Celestron's own?

Considering the glare from Venus that's nice resolution!

This planetary grouping from 20th March around 5.30am shows Saturn to the left with conjunction of Jupiter above & Mars below, sharp eyed may also see...  Io, Ganymede & Callisto in a string just right of Jupiter.

Thank you for kind feedback, lucky to get a short break in the clouds before we were hit with a heavy shower.

Derek, well we took a few knocks since we last saw you, just hit with one thing after another which kind of killed my enthusiasm for anything including imaging & astronomy, I guess we all go through times like that but otherwise all fine thank you.

Scope been sitting under a dust sheet past couple of years but I recently bought a HSM (motor focuser) from Starlight Instruments and waiting 3 Astrodon filters on backorder.

Hopefully get back up to speed later in the year, just difficult to plan ahead for any starcamps at moment apart from current situation.

Hope yourself and Annette are well too!

Just a quick cropped image of the Venus/Pleiades conjunction with Hyades looking on by moonlight from last night.
