Caldwell 39 (NGC 2392)
The Eskimo Nebula

Planetary Nebula in Gemini      RA 07h 29m 12s  Dec +20° 55m 00s


This image of the Eskimo Nebula was captured by Mike Lancaster on the 22nd January 2022. It is a stack of eight 5 minute exposures taken with a Mallincam Universe camera using a gain of 20 dB at full resolution (i.e. no binning), using a 0.5x Mallincam focal reducer and Astronomik CLS-CCD filter through a 10" Meade LX200 ACF SCT. This setup was mounted on an EQ8 mount and guided with a Lodestar camera through an off-axis guider using PHD2. The images were stacked, cropped and processed in Nebulosity 4 and Photoshop Elements 2020.  Image © Mike Lancaster.




Mike Lancaster captured this image of the Eskimo Nebula on the 8th March 2014. It is a stack of nine 30 second exposures taken with a Mallincam Xtreme X2 camera at AGC2, using an MFR5 focal reducer and Astronomik CLS-CCD filter through a 10" Meade LX200 ACF SCT. The images were stacked, cropped and processed in Nebulosity 3, Photoshop Elements 7 and Astronomy Tools. No guiding or dark frames were used.  Image © Mike Lancaster.




The following is an image of the Eskimo Nebula (Caldwell 39/NGC 2392) in Gemini and was captured by Adrian Brown on the 19th February 2005. The image is a stacked composite of eighteen 90 second exposures taken at f/10 with a Celestron C11 and ATK-1C combo. Adrian captured 60 minutes worth of raw images but comments 'my drive isn't really good enough for 90 second un-guided exposures and I couldn't use most of the captured images. Still, even with the egg shaped stars its quite an interesting image. The nebula was quite bright and visible in a 25mm eyepiece, even though the Moon was also in Gemini at the time!'  Image © Adrian Brown.
