IC 5070 - 20 hours on the Pelican Nebula from the backyard


Very pleased with how our IC 1318 (The Sadr Region and the Butterfly Nebula) image turned out with over 40 hours of data, I decided to start another large project, this time with a different telescope and mount. This was also our first time using the 3nm narrowband Chroma filters!


This time, it was time to hunt another flying living thing.. not a butterfly, but a Pelican!


The setup used to capture IC 5070

For the Sadr Region, I used the tiny Meade 70mm APO Refractor telescope and our Orion Atlas EQ-G mount.


This time, I wanted to use our new mount, the Paramount MyT from Software Bisque (make sure to read our full review!) and yet another Meade: the Meade 6000 series 115mm APO which is pretty much a bigger version of the 70mm.


I wouldn't be able to carry the whole setup in and out easily this time as I did with the small Meade 70mm and Atlas EQ-G. I still wanted to make sure I made my life as easy as possible though and so kept the camera and all the cables attached to the telescope at all time.


Every night, I would carry the mount out, attach the counterweights followed by the telescope/camera so it was still pretty quick.



It gets very hot pretty early here in Vegas so I would wake up every morning at 5AM to put everything back inside or the metal on the mount would burn my fingers after sunrise.


The Pelican Nebula contains several "Herbig-Haro" objects, which are jets of gasses and other matter being ejected at hundreds of miles per second by the newborn stars.

The photo on the left shows HH 555 (the thin "pillar" near the right), the most active Herbig-Haro object in the Pelican Nebula.



These objects, when colliding with the surrounded dust of the nebula, create gigantic bright shock waves. These jets will disappears over time as they disperse in space.

How to find the Pelican Nebula?

The Pelican Nebula is located in the constellation of the swan: Cygnus and is best photographed in Summer. Look for Deneb, the brightest star in the constellation at the tail end of Cygnus and move slightly westward until you find the Pelican.

Despite being very large, you will not be able to spot IC 5070 with the naked eye, as the gases are spread out and quite dim. However, a pair of binoculars or small telescope (e.g. 3”) will reveal a faint patch of gray light.




Cool Facts
  • The "Cygnus Wall" is a dark molecular cloud that divides the Pelican Nebula from the North America Nebula

  • The Pelican Nebula is designated as both IC 5070 and IC 5067

  • The Nebula is very active and will look completely different in the future


Processing of the Pelican Nebula

Processing the Pelican Nebula was super fun. It is such a colorful target especially in the Hubble Palette combination (SHO).


As soon as the channels were integrated into a color image (read our tutorial about how to combine narrowband channels if you are not sure how to), I processed the file using our usual, basic workflow that can be found as a PDF "follow along" file HERE.

What did each narrowband channel look like?


You might be curious to know how much data was visible for each narrowband channel. Below you can find the stacked image for each narrowband filter.


  • Hydrogen Alpha (left)

  • Sulfur II (center)

  • Oxygen III (right)


The Pelican Nebula was more prominent in Hydrogen Alpha (not a surprise), but you can see that both Oiii and Sii filters also showed some great textures.



What scared me is that our S channel looked... terrible. It was very fade and was suffering from what appears to be terrible light leak. I tried to ignore it and played with DBE very harshly to be able to get as much data from it as possible.


Below is what our three channels looked like when combined. To be honest, this was already so pretty and I almost wanted to just not process it at all and be happy with that 😅



Final Thoughts

The Pelican Nebula is such a beautiful object! Make sure to frame the object the way you want it, plan your shot the day before with apps or softwares like Sky Safari or Stellarium to get as much gas as you can depending on your field of view.


We are in love with the final image we got and might hang it on our wall! If you'd like to do the same, you can get a print of the Pelican Nebula either on paper or metal HERE!

ASTROPHOTOGRAPHY TUTORIALS





GALACTIC HUNTER BOOKS

Description: Discover 60 Deep Sky Objects that will considerably improve your Imaging and Processing skills! Whether you are a beginner, intermediate, or advanced astrophotographer, this detailed book of the best deep sky objects will serve as a personal guide for years to come! Discover which star clusters, nebulae, and galaxies are the easiest and most impressive to photograph for each season. Learn how to find each object in the night sky, and read our recommendations on imaging them in a quick and comprehensive way. Each target in this guide contains our advice on imaging, photos of expected results, and a useful information table. We've also included a few cool facts about each target, a map to find it in the night sky, and more!

Description: The Astrophotographer’s Journal is a portable notebook created for the purpose of recording observations, cataloguing photographs, and writing down the wonderful memories created by this hobby. This book contains more than 200 pages to memorialize your stargazing and imaging sessions, as well as a useful chart on the last pages to index exciting or important notes. Read back on the logs to see how much progress you have made through the months, the problems you overcame, and the notes taken to improve in the future. Just as the pioneers of astronomy did in their time, look up and take notes of your observations as you are the author of this star-filled journey.

Description: The Constellations Handbook is a logical guide to learning the 88 constellations. Learning the constellations is difficult. Remembering them is even harder. Have you ever wanted to look up to the night sky, name any pattern of stars and be able to tell their stories? This book groups the constellations in a logical order, so that the reader can easily learn them by their origin, and see how their stories interact with one another as a group. The last pages of this book include an index of all 88 constellations, each with a slot where you can write your own personal tips and tricks in order to memorize them with ease. The Constellations Handbook is not just another guide listing all the constellations from A to Z and their location, it is the perfect companion for stargazing, and a learning journey through the ages.
