Hi Bob,
Venus is nice now.
Some clear nights.

I also saw Saturn for first time. It is very low for me.

Haven't seen any NLC.

225x? 80mm refractor.

Regards,
David

Hello David, you are right to query the magnification. Actually the magnification (x165) is the correct figure; the wrong one, I now notice, is the focal length (8mm) of the eyepiece when it should read "11mm Tele Vue plossl" - now edited. Good job someone is on the ball!
You might also notice that I have swapped from the 90mm refractor, back to the old faithful 80mm after I have cleaned the objective (first time in 25 years) and changed the old, worn focuser for a new one. The 90mm is a good double star instrument but I prefer the 80mm for the Moon and planets. Old habits?
I'm looking for NLC but no luck yet.
Kind thoughts to you, Bob

Venus seen easily and quite bright with unaided eyes and distance glasses 4 minutes before sunset this evening in a transparent sky.

I haven't yet seen any NLC this season.

2018 June 15, 21.05 UT. 80mm achromatic refractor f11.4, x165 with 11mm Tele Vue plossl and x2 TV Barlow. Seeing Ant IV, transparency good, sky - twilight. Disc diameter 14.2 arcsec. Phase estimated at 72% by eye with W15 yellow filter, comparing the eyepiece view and interpolating with 5% incremental phase profile diagrams. Reliability poor due to seeing and no further disc work attempted.
Best wishes, Bob
