David Slack Astrophotography
North America & Pelican Nebulae in HaOiii
Added 10 x 5 minute Oiii data to the 54 x 5 minutes of Ha from the night before, cloud prevented me from getting more Oiii unfortunately. New Takumar lens performing very well even with the relatively high band pass of the Oiii filter I use. Equipment: SXV-H9 CCD, Asahi Takumar SMC 135mm lens @ F3.5, Baader 7nm Ha filter, Astronomik 12nm Oiii filter and HEQ5 pro mount.
