Description

We moved into a new house in central Portland Oregon a few months ago. I wasn't sure I'd be able to image from here given the small yard and bright lights. But narrowband to the rescue!

This is primarily narrowband data taken with a QHY367C (Yes, that's a color camera), using a dual band Ha/OIII filter. Bandpass for both is about 10nm which is great for a dual band filter but worrisome shooting in the city. To get some color in the stars I added some color data I had shot from a nearby dark site. So the color is 50% NB and 50% broadband while the luminance channel is Ha/OIII.

75 300 second narrowband subs were used, total of 3.75 hours. Ain't CMOS grand?!
