The “Ram’s eyes” and powdered glass !

Swad. 30/9/18 C6r 22mm and 5mm LVW

Set up after 6, four forecasts promised clear skies , wall to wall. Just a thought and I covered the mount . It then rained very hard !

After the rain, a few hours before the moon. These are ace. The Cygnus clusters were just stunning !

Mesartim. What a bright stunning sight at low power. Glaring out of the dark : The “ram’s eyes”!
1 Arietis. (01h53.5 +19 18′ ) a 2.9″ split , giving yellow and blue.
λ Arietis (SAO 75051 ) yellow and blue.
30 Arietis (SAO 75471)

I got 33 Arietis with ΟΣ43 at one side . ΟΣ43 ιs a bit below one arc second. The seeing was ultra stable. I could just about squeeze out a peanut shaped diffraction disc. ( remember that we don’t actually see stars, your Optics squeeze the light into diffraction discs. By slight defocussing you can get very close bright companions to show up) Diffraction discs by defocussing are very handy for testing out refractor Optics.

I’ve marked the best of the little known Cygnus and Vulpecula clusters.They really are most spectacular , powdered glass really hits the mark here in NGC 6819.

I turned to Cygnus high in the south west as it’s opposite the moon glow. The open clusters really showed up. I’ve marked the best ones here with asterisks.There are some favourites here.

The open clusters are temporary . They don’t have the tight centres and gravity of globular clusters to hold them together. Sooner or later they drift apart to leave lonely stars. Be interesting to find out if our own Sun was part of a cluster or constellation !

The targets found are fairly easy and ideal for moonlight and other light polluted skies , Nick.
