Starlight-Xpress SXV-H9 CCD, Asahi Takumar SMC 135mm lens @ F3.5, Baader 7nm Ha filter, Astronomik 12nm Oiii filter, ZWO ASI120mm based finder guider and a HEQ5 pro mount

This narrow-band image is my first result using a newly acquired Asahi Takumar fixed lens from circa 1970, at the bargain price of £50!
The lens permits a wider field of view with the small CCD sensor I use. It comprises 54 x 5 minutes of Ha exposure and 10 x 5 minutes of Oiii exposure.
