I got out in my backyard in Rye, NH, last night for about 90 minutes before moonrise and will try to get out again later in the evening tonight and tomorrow night if the weather cooperates:

 

Some quick notes on targets that were (mostly) new to me and sourced (mostly) from Don's 500 Best DSO target list:  https://www.cloudyni...-best-dso-list/

 

Conditions
Rye, NH. 8:20pm – 9:40pm. 54 degrees, 20.2-20.4 MPSAS. Transparency average+. Seeing average. A fair amount of dew. No wind – pleasant evening.

 

Equipment
Telescopes = 10” f/4.7 dob. EP’s = Ethos 10 but mostly Ethos 8. Paracorr.

 

Aquila
• NGC6709 open cluster – nice target. Reminds me slightly of Caroline’s Rose.
• NGC6756 open cluster
• NGC6756 open cluster – small and faint. Reminiscent of a globular cluster.
• NGC6781 planetary nebula – the Ghost of the Moon. Faint and ethereal. Nice!
• NGC6804 planetary nebula

 

Sagitta
• Palomar 10 – could not detect
• M71 – excellent! Great star fields around this target

 

Delphinus
• NGC6891 planetary nebula
• NGC6905 planetary nebula – the Blue Flash Nebula. Really like this target. Very bright and distinct and the star fields around it are amazing.
• NGC6934 globular cluster – fairly bright. Not much resolution at 175x. Not enough stability to get resolution with Ethos 4.6mm or 6mm.
• NGC7007

 

Equuleus
• NGC7015 galaxy – could not detect

 

Cygnus
• NGC6819 open cluster – excellent cluster:  a rich field of fine stars. Framed by a triangle of two bright stars and a wide double.
• NGC6819 open cluster
• NGC6866 open cluster – Kite Cluster. Again, amazing star fields all around.

Nice report and enjoyed reading your notes. I see it's getting cool in NH.

Best,

I am learning that September through November is one of the best time for stargazing up this way - it gets dark fairly early, the bugs stop flying, and it isn't challengingly cold. I am at all of 50 feet above sea level, so I'm looking through a lot of atmosphere, but we are just .5 miles from the Atlantic Ocean which really helps with keeping the skies darker than they would be otherwise.

One note:

Palomar 9 in Sagittarius is in my list of 500 DSOs, but not Palomar 10 in Sagitta.

It's a bit tougher than Palomar 9, but still one of the Palomar globulars visible to average sized scopes.

Keep after it, Wyatt.  You could use a bit darker skies to make it easy.

I will have another go at it - and with some more resolve next time! This time out was just relaxing and looking around, but it was still great to have a whole list of new targets to go after.
