With the summer targets drifting away from the northern hemisphere’s night skies, I decided to put a stop to this target.
Located on the Vulpecula and Cygnus border, Sharpless 92 is quite a challenging target because how faint it is and because of the fact that it is located in a very rich star field.
Shooting faint targets at f6.5 is not very easy but using 3nm filters makes the job a little bit easier. I did my best to bring out this beautiful target and even though, I think that more integration time is needed to make it pop even more, I am happy with the result.
