Description

Looking through my favorite book "The Night Sky: Observer's Guide" I found this interesting nebula in Sagitta. It is an emission nebula that is fairly large and very faint. In order to capture the nebula I had to use 4 minute exposures with 11 inch SCT and ZWO ASI2600 OSC. I took 90 images with ZWO ASI2600 set of 0 deg C, gain 100, and binned 2x2. The Moon rose during the night so the sky got progressively brighter. Processing was done with Pixinsight. I tried both using Star Reduction techniques, and without star reduction techniques and decided that using star reduction minimized the very nice dust lanes. So I settled on not using any star reduction.
