Albino Butterfly Nebula (NGC2440)

NGC 2440, also known as the Albino Butterfly nebula, is an very small (~10 arc minutes) but bright planetary nebula.

The central star of NGC 2440, HD 62166, is one of the hottest known, with a surface temperature near 200,000 degrees Celsius. The complex structure of the surrounding nebula suggests to some astronomers that there have been periodic oppositely directed outflows from the central star, somewhat similar to that in NGC2346 (The Butterfly Nebula), but in the case of NGC 2440 these outflows have been episodic, and in different directions during each episode. NGC 2440 lies about 4,000 light-years from Earth in thedirection of the constellation Puppis. It was discovered by William Herschel on March 4, 1790.

This image was taken under less than ideal conditions unfortunately, but wanted to post becasue I found it to be such an interesting object. It's extremely small for my 140MM refractor, and I had orginally planned on shooting with a 4x barlow to better scale the object but the conditions this night wouldn't permit that level of magnification, so I had to settle for shooting with a 2x barlow. The core of the nebula was brighter then expected, and required special processng to balance with the fainter surrounding lobes of the nebula.

I'll look to revisit this object again in the future.....either with more aperture, steadier skies, or ideally both! :-)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
