The Heart Nebula
=============

For some reason, I keep coming back to this object. I just love all of those fine details in the heart nebula and it's neighbour, the fish head nebula.

In the center of the heart nebula, there's a small open cluster of stars, called Melotte 15. These stars are responsible for the ionization of the surrounding gas, making it glow in the characteristic red hue of hydrogen alpha emissions.

The fish head nebula, also known as IC 1795, is a bright emission nebula, located in the same star-forming region as the heart nebula. It's a bit fainter than its neighbour, but still shows a lot of fine details.

I have a question for the #Astrophotographer and #Mathematician folks out there.

What is the smallest number of frames you could perform a drizzle transform on?

Could you, for example, perform it on two frames, and then submit that image to a livestacking process?

Does this idea even make sense?

As for "Why do this?", I am looking at the #SmartTelescope world, and wondering if you could perform the resolution increase in conjunction with live stacking, without resorting to post-processing. This is to attempt to allow a software-only capability upgrade, while still maintaining the convenience.

I figured I'd ask here first, because (conceptually) it seems almost too simple.
