It's nice to make a black and white image
after so colorfull shots.
In the image there is two main objects, IC410 and IC405, sometimes
called as a "Flaming Star Nebula".
IC405 is a emission nebula but it has reflecting nebulosity too.
In my heavily lightpolluted location it's not easy to capture.
Trough Hydrogen alpha filter just emission part is captured.
Some info in Wikipedia: http://en.wikipedia.org/wiki/IC_405
Camera, QHY8 - Filters, Baader 7nm H-alpha - Optics, Tokina AT-X 300mm @ f2.8
- Exposures, 5X 1200s H-alpha + flats and bias - Guiding, LX200 GPS 12" + PHD-guiding and QHY5
Ok. I can't live without colors, let's face it,
so I added this false color Ha-composition here.
Red = Starless Ha 100% R = 0% B = 17% Ha (Works as a H-beta substitute)
