NGC 6960. NGC 6992 and Pickering's Triangle.

This image of the Cygnus Loop was taken using Astronomik narrowband filters attached to the front of a 135mm lens piggybacked on my ten inch reflector mounted on a Vixen Atlux mount. I was also using an Atik 383L mono CCD set on times 1 bin mode. 

I captured two minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.

The total exposure times were 40 minutes using a H A filter, 30 minutes using an O111 filter, 20 minutes using a S11 filter and 6 minutes using a blue filter.

PIN G077 .5-01.71 The Soap Bubble Nebula, NGC6888 The Crescent Nebula and NGC7026 the Butterfly Nebula.

I took this image about 2 hours before dawn arrived. The sky conditions were very clear and dark with stars visible down to magnitude 5.2.

I was using a 135mm lens with narrowband filter attached to the front piggybaced on my ten inch reflector mounted on a Vixen Atlux mount.

I captured two minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image. The total exposure time was 45 minutes using a H Alpha filter, 30 minutes using an O111 filter, 25 minutes using a S11 filter and  4 minutes using a blue filter.

NGC7000, The North American Nebula.

This patch of nebulosity lies about one degree east of the bright star Deneb in the constellation of Cygnus the Swan. I piggybacked a 135mm lens using narrowband filters attached to the front of the lens. I was also using a Vixen Atlux mount, a ten inch reflector and an Atik 383L mono CCD camera.

I captured two minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.

The total exposure time was 40 minutes using a H Alpha filter, 30 minutes using an O111 filter, 25 minute using a S11 filter and 5 minute using a blue filter.
