Planetary Nebula Abell 38 (PLN 346+12.1)

Hello,

Continuing with my equipment shake down after a long lay off, on Saturday night 12th June, I stumbled across Abell 38 located in Scorpius. According to The Sky 6 Pro, this is a rather faint, Magnitude 15.7 Planetary Nebula.

Mewlon 180 F12 with x0.8 Reducer/Flattener operating at F9.6 (efl 1728mm), SBIG ST7 ccd camera, 9x10 minute exposures. Taken from suburban Brisbane.

Object name: PLN 346+12.1 aka Abell 38
Magnitude: 15.7
Equatorial: RA: 16h 24m 00s Dec: -31°46'30"(current)
Size: 154"x94"
Object type: Planetary Nebula
Source catalog: PLN (Planetary Nebulae)

To reveal the PN, I created 2 frames in CS4; one for the background stars and the other for the PN which I then blended to minimize the background noise from pumping the data to reveal the PN. I didn’t even attempt to acquire any RGB data due to the faintness of this object!

Cheers

Dennis
