Finished: Wednesday, March 18, 2020 at 1:13 AM
Seeing: 3/5
Transparency: 4/7
Number of observations: 29
Session Notes:
Clear with low crud in S reflecting ABQ; lightdome NW.
Cas sinking into light dome.
Polaris/Betelgeuse alignment w/12.5mm error -0.428
8mm is at limit of seeing.
Humidity higher than would like, decreasing transparency. [PWS shows 75% rel, 32 deg dew point @ midnight]. Condensation showing on chair ~ 12:50, also notepaper moistening.
Neighbor across street keep driving in and out of driveway, turning car lights on and off, pointing toward observatory. V. annoying.

26mm+NPB: responds, but as well as with OIII.
13mm: ghostly (gray), large, disc-like. Involves star at NE edge.
13mm+OIII: star barely present. Disk shows up much more nicely. May be star opposite side disc. No other evidence structure.
13mm+NPB: Does not respond present as well as with OIII. NE edge star present. Evidence for second stellar-like point at AV3.

Found: True; Telescope: Dob; Eyepiece: 8mm Ethos; Magnification: 265x
Observation Notes:
w/NGC3636
26mm: Adjacent to bright [6.5m] field star. r. faint, but greater sb than 3636. no evidence nucleus. w/NGC3636 and field star forms right tri with field star at right angle.
13mm: readily identified. close to edge of seeing, however: can’t get stars to focus to points. 8mm: readily identified, but seeing stinks.

Found: True; Telescope: Dob; Eyepiece: 13mm Ethos; Magnification: 163x
Observation Notes:
13mm: gal. near field star. R, fuzzy, almost uniform brightness across body. small.
26mm: very small, faint, definitely non-stellar fuzzy.

ID: NGC3640
Type: Galaxy; RA Dec: 112107+0314; Constellation: Leo
Name: II-33; Mag: 10.3; Size: 4.1×3.4

Found: True; Telescope: Dob; Eyepiece: 26mm Nagler Type 5; Filter: DGM NPB; Magnification: 82x
Found: True; Telescope: Dob; Eyepiece: 13mm Ethos; Magnification: 163x
Observation Notes:
26mm: gal. small, faint, non-stellar fuzzy. w/halo, nucleus suddenly brighter toward center.
13mm: larger: halo shows larger, better; nucleus larger, non-stellar. Perhaps some evidence of structure but sky is not cooperating.
