Another image from my Bright Tiny Object (BTO) week…
NGC 2392 The Eskimo Nebula, also known as the Clown-faced Nebula, Lion Nebula, or Caldwell 39, is a bipolar double-shell planetary nebula (PN).
A dying star that has blown off it’s outer atmosphere.
The blue green Parka looking outer envelope is how it got its nicknames.
The Planetary nebula is tiny in most telescopes but is very bright, shining at magnitude 10.
It is located 6,520 light years away in the constellation Gemini.
The Eskimo’s face is hot in X-rays, a result of interactions between the star’s fast winds colliding with the shell of the nebula.
Here, temperatures reach some 2 million degrees Celsius, much hotter than the surrounding ejected material that glows at around 14000°C
I captured this image with a Celestron 6 inch F5 Newt. Scope, Bisque MYT Mount, ZWO 224MC Uncooled Cmos Camera, ASI Air App acquisition, via Wifi to IPAD,
No Auto-guiding, no filters, just “Lucky Imaging Method”(short exposures stacked) 60 x 10 second exposures, 10 minute total integration time
from my Backyard Observatory in Dayton, Ohio on 02-20-2022.
