Aug 7th, 2016 – Butterfly Nebula (IC1318)

First of all do let me know what image do you like most with STARS or the STARLESS version.

It was my first attempt to do astrophotography from the backyard of my humble Braeburn apartment in downtown Ann Arbor – MI, I setup my EdgeHD 9.25” with hyperstar and ASI1600 at gain 300 and Astronomik 2” Halpha 12nm filter, IC1318 was pointing straight up and that’s why I was interested to see how much details and light pollution I can capture with 2min subs.

I ended up capture all three filters (Ha, OIII, SII) 25subs each, unfortunately after stacking my OIII and SII appears to be useless, but my Halpha was looking promising.

Now usually I only Maskstretch the image and play with level and curves to enhance the signal and do some sharpening and post a gray scale image of Halpha, the problem with this image is the more I enhance the image the more the stars will blow up and destroy the nebula details in the background, I believe the reasons are the high gain as well as the light pollution effect that reduced the nebula signal.

Briefly said what I did was the following:

1) Removed all the stars from the image (Tedious job using Photoshop)

2) Stretch and sharpen (Using Annie’s Astro Photoshop actions)

3) Converted to a color image (Using Photoshop actions Astronomy Tools v1_6 -> B&W to Ha False Color Black Space)

4) Restore Stars (Put back the stars layer from (1) and blended it as LIGHTEN)

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.
