A good favorite after some other duds I hit tonight...

 

9.1.19
9:45- 11:15pm
Seeing 5-7Pk.
Trnsp:Vari.

No luck doubles first:

Zeta Herculis
Again, no luck. Perhaps the airy disc was oblong?  Maybe. Don't know. Not a chance. Thomas Jensen managed this with a 60mm refractor so I'm a bit bummed. Granted haze and a Pickering 6-7.

Pi Aquilli
Forget it . Primary is variable and it must be in it's dim point because it glowed feeble at about mag 7.

12 Aquarii
Too dim to see companion . Tried with 5mm too.

Delta Cygni
Just a lone dancing diffraction pattern. As predicted in ASTROPHERIC, seeing would decline as they forcasted.  Stars started to twinkle.  Still nice airy discs, just too busy for more discerning observation.

Rho Capriconis
Nothing. Dimmed a bit by haze to but the 1.9" seperation and over a magnitude differential was too much. Nothing with 5mm either but a lone dim diffraction pattern.

 

Ok the WINNERS!!!

 

Gamma Delphini
The old fav is seen again. Nice warm candle tone at 48x and clean assymetric brightness. Casual double and pretty.
But the view here is another Double-Double as there is a dimmer tight pair: OR Delphini.  Sensitive to catch it 48x with light pollution too but it shows. Best at 83x: better color in Gamma but also the assymetry better in OR Delphini. Excellent duo if only optically connected.

Zeta Aquarii
Finally a bright tight binary - a cream pairing, beautiful at 119x like one half of Epsilon Lyrae - but again, pale cream. Best at 167x lending it the textbook look. Slight assymetry in mags noted.  Only one diffraction ring seen about primary  partially and dimmer about secondary.  Slight color effect here: primary is cream companion appears dimmer white.  Best so far of the night.

With haze increasing at one point I went for Albireo...

Brilliant of course with the golden component always more colored than the "blue" companion.  At 119x, though uneeded it showed the technical diffraction rings nicely .  Best view at 38x.

 

NGC6543
I was surprised to see that I could readily identify this planetary with only 31x.  It was the odd *star* in a faint field.  A star is just never that bloated with steely points in the same field.  Color at different mags was pale slate.  Best view was at 167x - definitely elliptical appearing. For the briefest moments however, I saw a mottled edge here and there like something defining just on the edge of detection.  I could've gone up to 308x as this planetary does well with virtually 100x per inch, but it was getting late.

Pete,

Very nice sketches of these pairs.

NGC 6543 is a nice and easy planetary to locate and bright enough to pull in with smaller scopes as you have demonstrated. Well done.

 

Frank :)

That's the Cat's Eye nebula. You make it look easy. Glad you're getting out, dude. Wish I could.

Well its surface brightness is among the best. Thanks dude.
