Last evening I woke at 2am and took a peek out the window and say all the stars and Milky Way so had to go out and try my new Celestron K40, along with the vintage 12, 9, 7 Celestron Volcano Abbes and Dakin 2.4x Barlow I recently acquired for a classic single-coated ocular fest. So took the little Vixen 81S out for some observing. Weather was so very nice with a light breeze and so much temperate than the day before where it went up to 90 degrees F here. So was enjoying the temp and breeze as much as the sky.
Saw a great array of objects over the next 2 hours: The Double Double, M57 (Ring), Albireo, M39 (OC), Lots of scanning around the stars in Cygnus, M16 (Eagle Neb), M17 (Swan Neb), M18 (OC), M21 (Trifid Neb), M8 (Lagoon Neb), M25 (OC), and Sagittarius Star Cloud. All grandly revealed with a bunch of vintage 1970-1980 Kellners and Orthos and a little 81mm Apo!
Swan (always enjoy this one) - https://lh3.googleus...dP2Zdm5yWCE0GPi
Lagoon (stole the show last night it was so spectacular) - https://lh3.googleus...T5wftbTt1H-eB2g
On the Double Double could not get a clean split with the 9mm (69x) as they were just a little too close for my taste, but the 7mm Abbe did it beautifully for my eye showing 4 clearly distinct non-touching star points (89x). Colorful Albireo was grand in the K40 in its normal configuration (40mm and 30+ degree AFOV), or with barrel reversed where it becomes a 25mm Kellner with a nicer 42 degree AFOV. M57 was stunning in 12 & 9mm Abbe (about 50x and 70x) showing a pronounced donut shape with a nicely dark center. And even with only a 42 degree AFOV the star field in context around it was beautiful! The Swan was as always simply impressive showing its shape and dark lane really nicely in the Abbes. But most impressive was the Lagoon Nebula. Amazing complex structure of star cluster and nebula and dark lanes and it was lit up like a little neon glow framed end-to-end in the little Abbe's AFOV. I stared at that one for a long long time it was so beautiful.
Then after some sitting time enjoying a little naked eye observing palmed the 4 eyepieces in one hand, picked up the scope and mount in the other hand, and went back to bed. No doubt about it, Orthos and Kellners very much still rock!!
