Description

Sh2-155, the Cave Nebula in Cepheus. This is an (Ha) SII-Ha-OIII image of 280-140-120-120 minutes respectively. The Ha data was captured last July 2007 and the OIII and SII data was captured on September 2, 2008. Because of the different rotation angles of the camera between the two imaging sessions I had to crop a lot of the image out. Imaged with my Tak TOA130 with reducer, ST2000xm camera, and NJP mount. Total exposure was 540 minutes (9 hours). Next year Id like to shoot this object with more exposure time and with my FSQ106. All imaging was done in Redlands, Ca.
