Happy Halloween! In this version of the Wizard Nebula I increased the sub-exposures from 15 minutes to 30 minutes which required guiding. I then stacked 11 images. This increased the resolution substantially.
The wizard nebula is a cloud of interstellar gas and dust that lies about 8000 light-years from us. In a telescope you would probably only see the cluster of stars and not the nebula itself since it is very faint.
This is another Halloween treat. Can you see the Wizard in this image of the Wizard Nebula? The total exposure time was about 6 hours through an H-Alpha filter. I will be working on a color version.
I was surprised to see the gremlin’s face when I processed this image of the Bubble Nebula (NGC 7635). This was obtained by stacking about 13 hours of exposures (39×10 minutes and 28×15 minutes) taken with the Astro-Physics f6.3 130mm refractor in combination with the QSI 690 camera. My Astro-Physics mount is getting more accurate as time goes on, so these exposures were done with no guide camera. I hope to gather more detail on this nebula over time.
