I will go for a star party in Sweden and the club there has a 60 cm ( 23.62” ) f/6 at 40 mm thick ( rather thin at ratio 15;1 ) made in France by Cardoen.
Sky can be pretty good and maybe at best around SQM-21.5, but as this time of year the moister is a issue.
But the telescope is in a dome way above ground, but sky will still probably has moister.
The area is not that great on the Bortle scale and nearby cities do pollute.
One of the galaxy's I’m after in Hercules is the 2MASX J16394598+4609058 I saw at OSP in Howards 28” ( or say I briefly saw it )
I will use Ethos EP and say 8 mm that give 450X and a 1.3 mm pupil.
-Will it be a chance to see this galaxy and Hercules is at a decent position now.
The telescope track good and mirror was new coated last year.
