The Orion our eyes can't see

astrophotography imaging Orion

The Orion our eyes can't see

A goofy smiley face in space or the Constellation Orion... I'll leave that up to you to decide. I present the first processing attempt at my Fall astrophotography project-Orion as our human eyes can't see it. I captured this data over four nights from Oct 22nd to Oct 25th while on a vacation to see family in Phoenix Arizona. To that point, all of this was captured with gear that I was able to fit in my checked bag, along with a week of vacation packing making it a successful POC for full portable astrophotography. Australia here we come 😉

Orion is one of the, if not the most well-known constellation in the night sky. It's been the source of tales and mythology in countless cultures new and old from various tribes of Native Americans, to the Ancient Greeks, Aboriginals of Australia, Egyptians, and so on. I remember growing up and my dad never missing an opportunity to point it out to help get my celestial bearings.

Orion is widely known as the hunter and is often transposed as either facing the charging bull Taurus, chasing the seven sisters (Pleiades), or hunting a hare (Lepus). Within Orion, you'll find at least two of the ten brightest stars in the sky- Rigel in the lower right, and Betelgeuse in the upper left. Also visible here are a number of nebulous features from The Orion Nebula (M42), Horsehead and Flame nebulae, De Marian's Nebula (M43), the Rosette Nebula, and the Cone Nebula in the upper left.

This photo was captured using Zwo Narrowband filters for Hydrogen Alpha, Doubly ionized oxygen (Oiii), and Sulfur II as this was captured from a suburban location in Arizona. Pan right for constellation and rig photos. Final specs:
Total integration time = 15hrs

30x900" Ha (7.5hrs)
15x900" Oiii (3.5hrs)
