Subject: [QSI-CCD] Sh2-135 image

This is an image of Sh2-135 in Cepheus.? It's an emission nebula that isn't often imaged and then usually with wider field setups that also show some neighboring LBN objects.? I only added it to my target list recently after seeing someone else's image and noticing there was some structural detail that would work with a long focal length setup.? The image was captured during 5 nights in August-September 2023 under fair to average conditions while dodging summer monsoons.. Image acquisition was done with a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LHaRGB integration of 26.8 hours.



Thanks for looking,
Bruce W.
