M63 is a beautiful spiral galaxy located about 37 million light-years away from Earth. Below you can see our image of this target taken with our usual 8" Newtonian telescope and our ZWO ASI 1600MM camera. We did not spend a lot of time on it but it turned out beautiful and does not have much noise at all!
The Sunflower Galaxy got its name from its yellow core and the shape of its arms resembling a sunflower. Photographing this target is not difficult, but could be a little tricky for beginners due to its small size and the difference of brightness between the core and the arms. We recommend to aim for about three to four hours of exposures on this galaxy, as the beautiful details in the arms, or petals, might not show if the total exposure time is too short.
Processing the Sunflower is very exciting, as the galaxy will look somewhat dull until you adjust the colors and saturation to transform it into a beauty!
Messier 63 (LRGBHa), the Sunflower Galaxy
Camera: ZWO ASI 1600mm Pro Mono
Telescope: Orion 8" Astrograph f/3.9
Mount: Atlas EQ-G motorized Mount
Acquisition: ASI Air
Total Exposure Time: 2 hours and 42 minutes
Exposure Time per frame: 3 minutes
Filters: L (1.3 hours) / R (30 min) / G (24 min) / B (30 min)
LOCATING MESSIER 63
Just like M106, M63 can be found in the faint constellation of the Hunting Dogs: Canes Venatici. An easy way to find its location is to start from Ursa Major. Locate the last star of the Big Dipper’s handle, Alkaid, then begin moving towards the brightest star of the Canes Venatici constellation: Cor Caroli. You should spot your target about halfway between both stars.
The Sunflower galaxy is bright enough to be seen with binoculars and small telescopes, but you will only be able to spot a small gray smudge.
Besides M106, there are several other nearby objects that you could stumble upon while looking for the Sunflower, such as M94, M51 (The Whirlpool Galaxy), M3 or NGC 4631.
Pierre Méchain’s first discovery, in 1779
Is a member of the M51 Group
One of the first galaxies where a spiral structure was identified
SINGLE SHOT & PROCESSING OF MESSIER 63
We used four filters to capture Messier 63: L,R,G and B.
Below you can see the stacked images for each filter.
Messier 63, stacked images for L/R/G/B
Stacking these 4 filters into one image gives you what you can see below. Great details in the arms, a bright core, some gas on the outer edges and a few galaxies appear more obvious all over the image.

OUR CATALOG ENTRY VIDEO
Below is our short video about our capture on M63. This is one of these very quick update videos to keep our viewers up to date each time we image something that is not part of our Episodes and is added to our Messier catalog.
Messier 63 is not very large, but it sure is impressive! With the right processing technique, an astrophotographer can make its beautiful colors pop out in a magnificent way without over saturating the object. There are also some nice small galaxies throughout the image that become more and more visible as you process the photo.
We are happy with the result even though we only spent less than 3 hours on it. We can thank our Bortle 3.5 Nevada sky for this and the fact that we can now use a cooled camera!

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.
