North American and Pelican Nebulae
19/10/2003
Had a good night up at the club observatory. Danny Flippo and I teamed up to do a little wide field CCD imaging. We used Danny’s Johnson widefield adapter and my ST10 along with John Reed’s 135mm Olympus lens – it was quite a group effort!
The camera was mounted on top of Danny’s C8 using the club’s AP800 mount. The combination of the 135mm lens and the ST10 yeilded a field of view approximately 4 x 6 degrees! Since Cygnus was well placed we aimed just shy of Denub and shot 12 x 10 minute exposures of the North American and Pelican nebulae using an 11 nm HAlpha filter.
