The Whirlpool Galaxy
================

This is Messier 51, the so called Whirlpool Galaxy - an interacting grand-design spiral galaxy with a Seyfert 2 active nucleas, located about 31 million light years from us in the constellation Canes Venatici.

Discovered in October 1773 by Charles Messier, M51 (and its partner NGC 5195) is one of the most-observed and studied interacting galaxies. With an apparent magnitude of 8.4mag it’s relatively bright and easily visible with also smaller amateur telescopes.

Lens: Askar 1.0x Flattener
Camera: Canon EOS 6Da
Filter: Svbony IV/IR-Cut
Mount: Skywatcher AZ-EQ5 GT
Guiding: Svbony SV165 Guide Scope with ZWO ASI 224MC
Controller: ZWO ASIAir Pro

Integration time: 5hrs 50min

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.
