First sessions with the scope for a while. A bit of a random scoot around Scutum and then beyond. My sky has had a bad habit of being OK for galaxies for a while and then getting murky.
Thanks for looking.

2045 Seeing poor, transparency fair
NGC 6694/Messier 26 OC in Scutum
135x Very pleasing patch of 50-60 faint stars with one bright star at p edge. Looks about 10 N/S x 8 p/f with elegant curve of stars around then Np rim of a dark space on the N side of the cluster. Intriguing and complex lines of stars in this OC.
NGC 6705/Messier 11 OC in Scutum
135x Spectacular 14 square block of myriad faint stars riven by dark lanes to give appearance of a Chinese signature stamp. Many small bundles of stars delineated by dark patches and one bright star in the centre.
NGC 6712 GC in Scutum
175x 7 dia round concentrated GC with no central core. Many faint stars resolved. A small dark lane cuts into S edge. Sp and Np edges are sharpened by dark lanes that give the impression of the GC having a point towards the p.
NGC 6751 PN in Aquarius
175x Distinct round 30 dia grey glow with star very close to f edge. No detail apparent and no central star. With UHC filter, it brightens and I have impressions of dark patches inside the p edge. Looks smaller and brighter with OIII filter. (I am curious on cross checking with NGC/IC project the reports there include a distinct central star)
NGC 7009 PN in Aquarius
175x Always spectacular even in these poor conditions. Bright blue-green 1 glow elongated p-f and ansae discernible. Even better at 250x and ansae more marked.
NGC 7099/Messier 30 GC in Capricorn
Fascinating GC with 10 outer halo and dense 4 central concentration and a 2x1 p-f very dense core. Many stars can be resolved in the inner section and a couple of strands to the N. The outer halo is more extended to the Sp.

2045 Seeing good, transparency fair
NGC 6943 GX in Pavo
175x 3.5x2 f-p oval glow with marked but not stellar central brightening.
IC 5052 GX in Pavo
175x 6x1 elegant p-f sliver with no central brightness. Careful observation reveals faint mottling along the length of the galaxy
