Rosette nebula NGC 2244 – Taken under clear sky conditions. Heavy light pollution, stars visible down to magnitude 4.5.
Taken on 3 separate evenings using 80mm f/7 refractor, with focal reducer to f/6.3.Vixen Atlas mount PHD auto guiding Astronomik narrow band filters Sll, 2 hours Olll, 2 hours H-alpha 3 hour exposure. Captured 10 minute sub-frames with matching dark frames combined with flat field frames to reduce the effect of vignetting in the final image. The composition image taken using two telescopes 4” refractor and 80mm refractor total exposure time 9hrs 40 mins

IC410 The Tadpole Nebula. Image was taken under clear sky conditions under bright moonlight. Stars visible down to magnitude 4 so only narrowband imaging was possible . The telescope used was an 80mm refractor with a focal reducer making it F6.3 . Also using a Vixen Atlux mount with PHD auto guiding. The camera was an Atik 383L mono CCD camera with a set of Astronomik narrowband filters S11, One hour Olll, one hour and H-alpha, three hours. I captured ten minute subframes with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image. The composition image however was taken using three separate telescopes a ten inch reflector and a four inch refractor
