First time out with the new Binoviewers and they definitely make seeing fine details easier. I estimate that I can now see as much in AIII conditions as I could in cyclops mode in AII conditions.

The drawing is unfinished...... I had just started on the finer details when a sudden downpour started that had crept up behind me !!!!

Some interesting features :-

A - A dark patch in the North Polar Region - I have not seen that before.

B,C,D - Easily seen blue festoons. C had a nice white area by it's side and D looked to be a full loop.

E - A dark barge in the South south Temperate region.

A shame rain stopped play !!

Details - Intes Micro Maksutov 715 at x170(ish), seeing was AIII, temp was 4'C, altitude was 43', CM1=215.5, CM2=80.5, 21:30UT. Binoviewers with 18mm Orthos.

Very good indeed, the Festoons are great.

David, fantastic sketch. Interesting grab of that dark polar region. I have to keep an eye out for that.

BTW, binoviewers really do make a big difference. Somebody kick me if I ever let mine go...again.

Cue comment from Norme lamenting his lack of binoviewers... :lol:

David - what scope for this? The bowed out NEB neath the festoons looks like what I was seeing too . I applaud your notations! Nice work!

Rutilus, Jason, Pete - thanks very much for your kind comments.

Pete - I pinched the annotation idea from you :o - I used a Russian 7" Maksutov.

That's awesome! The same stuff going on there. It kind of makes you feel good when you can verify against another. Nice job guys.

Lovely detail, David! My binoviewer never leaves my focuser ever again, not even for difficult deep-sky work. Apart from the immersion that not even an Ethos may give you, it makes observing much more relaxed, seeing becomes a little less of an issue and therefore you make out the details a lot easier. And your drawing shows just that. Excellent work!

I'm also taken by David ("Dweller")'s work and the similarity with yours, so without any doubt you're both very fine observers. My compliments!!!

Peter

David, just saw that same cm. More later after tear down snd some sleep. Yea my skies are one giant bino! :) Wanna hear more about yours. More later.

Edit: okay back...

David, what a shame you could not finish with the finer detail. Don't be like that proverbial golfer having the round of his life and finishing up the 18th during the thunderstorm of the century. Stay dry. :)

I would have loved to see what finer detail awaited you. I caught that darker concentration in the north, too. That's an amazing feat, that stuff is low contrast and very fleeting. The festooning at this CM is pretty nice, just as you show. There is one festoon that rolled around later that is the massive festoon of all massive festoons. Huge, dark blue, with a true arch.

That dark barge in the south is the trailing edge of the cloud with BA embedded in it. Best I could tell, the rest of the south was pretty bland at this CM. The north, however, put on a show.

Can't wait to see how your binoviewer works out.

Beautiful work David,
I am thinking the binoviewer is the way to go. You have some lovely detail.
