Good finish of a great week

[YKSE]

ity 58-73% (forecast 60%-70%) dew heater no needed.

Temperature: 10°C - 7°C

Wind: 5-6 m/s

SQM 20.7-20.9 in zenith, average transparency

 

NGC 6578(PN-Sagittarius, mag 12.5, 8.5"x8.5"): Blinking with UHC didn't bring out anything, without checkingthe chart, tried on the three suspected ones by going up to 450x, no luck.

NGC 6741(PN-Aquila, mag12.3, 8"x8"): linking with UHC didn't bring out anything,  tried on the two suspected ones by going up to 450x, turned out to be true double stars.

Checking the chart back home, I relized that I should have tried on the neighboring fainter "stars".

NGC 7171(g-Aquarius, mag 12.1, 2.3'x1.4'):  A Herschel 400 II galaxy, AV in123x up to 200x, bright core, elongated, PA150.

IC 1417(mag 12.7,1.3'x0.4'): in the same 0.5° FOV, a bit tuffer than 7171, AV in 123x, elongated, PA120.

NGC 7180(g-Aquarius, mag12.6, 1.5'x0.7'): AV in123x up to 200x, elongated, PA110.

NGC 7184(g-Aquarius, mag11.0, 5.9'x1.3'): Herschel 400 II galaxy, DV in 71 up to 180x, AV showed larger elongated, PA60, looked like two bright cores in 71x, up in 180x-200x showed a star in one end.

NGC 7185(g-Aquarius, mag12.2, 2.3'x1.5'): AV in 71x, elongated, PA30.

NGC 7188(g-Aquarius, mag13.2, 1.6'x0.8'): AV in 71x and 123x showed it better, elongated, PA30.

NGC 7218(g-Aquarius, mag11.8, 2.6'x1.1'): DV in123x up to 200x, AV showed elongated, PA30.

NGC 7241(g-Pegasus, mag12.7, 3.4'x1.1'): Tried 71x-123x, couldn't see it.

In waiting for NGC 253 , 288 reach their height, some minutes spent on Cocoon nebula (IC5146) which I last observed a couple of years ago.

Cocoon nebula (IC5146) : nothing without filter, UHC (Astronomik and TS) brought it out. Just like others have comented, the view was lack-luster, not at all near the view of Veil or other bright nebulae, but, it was visible in direction vision, brighter than most mag 12 galaxies I've observed so far. Astronomik H-beta filter showed better contrast than UHC, in all filters, 4mm and 5mm exit pupil worked better than 3mm , which still showed it in DV.

NGC 253 or Caldwell 65(g-Sculptor, mag 7.2, SB12.2, 26.4'x6.0'): It was only 6° above horizon, I had not much expectations about seeing it, considering the other day's difficulty with similar size NGC 247, got positively suprised when it was visible in 71x, in DV!  it's brighter than many of Messier galaxies, 123x worked just as well, elongated, PA60.

NGC 288(GC-Sculptor,mag 8.1, 12.4'): globula clusters usually take good mags, but not this one, I slew to it with zoom in 123x, had actually difficulty to find it, as I expected something brighter, it was first after went down to 55x and 71x where it was barely seen in direct vision, up to 123x, it was only seen in averted vision.

NGC 210(g-Cetus, mag10.8, 4.6'x3.2'): DV in 71x - 123x, AV showed brighter core and oval shape, PA0.

NGC 488(g-Pisces, mag10.4, 5.4'x3.9'): DV in 71x up to 246x, around 150x best. slightly oval, bright core, PA100.

NGC 524(g-Pisces, mag10.3, 3.2'x3.2'): DV in 71x up to 246x, around 180x best. face-on, brighter core.

It was near 2 o'clock, clouds started to roll in as predicted, time to finish a great stargazing week.

 

Thanks for reading.

Congrats for some great sessions Yong!

[Piero]

Another very nice report! Thanks for sharing.  

[Yamez]

Brilliant observing report, lovely to read.

[Tzitzis]

Very nice report with lots and interesting targets!

[Pig]

Nice one there Yong   keep up the good work.

[FenlandPaul]

You've certainly packed it into those sessions, Yong - great write-up.

Great work as always Yong. Interesting to read your comments on the Cocoon and Sculptor Galaxy particularly. The Caldwell list seems to be a real mix of the impressive and the very faint!

[YKSE]

Agreed, Caldwell lists are certainly a larger mix of flavours than Messiers

[Special K]

Great one Yong!  Loads of stuff in there including some definite challenges to go back for.
