Messier 97 (top) and Messier 108 (bottom) in Ursa Major are two celestial objects that appear to be close to each other but in reality are separated by an immense distance in space.
M97, known as the Owl Nebula, is a planetary nebula located inside our own galaxy at about 2,500 light-years away and has a diameter of about 2 light years. It was discovered by Pierre Méchain in 1781 and it was included in the famous catalogue of Charles Messier as entry 97. Two prominent dark spots inside the nebula give the appearance of an owl’s face.
A planetary nebula is formed by the expanding shell of gases blown off by a dying star at the last stages of its life. The expanding shell is heated by the radiation of the central star (a very faint 16th magnitude star in this case) and it glows mostly in green light of oxygen atoms. The nebula will completely disperse into space over the next several thousand years, while the central star will cool and fade away over the next several billion years.
The estimated age of the Owl Nebula is about 6,000 to 8,000 years.
Galaxy M108, the Surfboard Galaxy, is harder to see in a telescope than M97, because its light is spread out over a larger area. It happens to lie near the same line of sight as M97 but is located at about 45 million light-years away. M108 is an edge-on spiral galaxy, heavily obscured by dust. It was also discovered by Méchain.

Imaged during the night of 27-28 April 2022. This is an image of two very different Messier objects in the same field of view.
M108, also catalogued as NGC 3556, is nicknamed the Surfboard Galaxy. It is a barred spiral galaxy system some 46 million light-years distant. The galaxy appears almost edge-on from our perspective.
The galaxy was discovered by Pierre Méchain in 1781 some three days after he had discovered The Owl Nebula, the second object in the image (lower right).
The Owl Nebula is a planetary nebula. This is a type of emission nebula which consists of an expanding shell of ionized gas ejected from a central star (visible in the image) late in its life. This object lies rather closer to us at "only" 2000 light-years!!
Both objects reside relatively close to Merak, one of the pointer stars of The Plough or Big Dipper.
Messier catalogued both as M108 and M97 in his famous catalogue.

Taken on the night of 11th April. The planetary nebula M97 aka The Owl and the galaxy M108. M97 is a planetary nebula at a distance of about 2000ly and the galaxy M108 is around 46 million ly! A lovely pairing. There are myriad other galaxies in the frame if studied carefully.

Hi Folks,
A new imaging project has been published on Cosgrove's Cosmos!
This image contains two Messier Objects in the same frame:
Messier 97, the Own Nebula, and Messier 108 - also known as the Surfboard Galaxy.
M97 is our near neighbor - located only about 2,030 light-years away.
M108 is a more distant neighbor - located a whopping 28 Million light-years away!
The full story around this imaging project, including a detailed, step-by-step processing walkthrough, can be seen on my web post:
cosgrovescosmos.com/projects/m97-m108
This imaging project represents some firsts for me:
- It is the first project I have undertaken for 2023
- It is the first project I have done since recovering from my recent surgery
- It is the first imaging project done since I upgraded my William Optics 132mm scope with a flattener/0.8X reducer and changed the camera to a ZWO ASI2600MM-Pro
-It was the first chance I had had to shoot since the smoke plume from the tragic wildfires in Alberta has shut me down!
While I was pleased with the detail I was able to capture in this image, It is not one of my favorite images. I think the smaller scale of the objects creates an image that needs more drama and impact. What do you think?
Even so, I am glad that I finally was able to capture and process photons and get back into the game for this year!
Thanks for looking!

La congiunzione tra la cometa 41P/Tuttle-Giacobini-Kresak e la nebulosa Gufo e la galassia m108 del 22 marzo . La trasparenza era pessima , a causa di una leggera foschia , e anche l elaborazione è stata ardua a causa del rapido moto della cometa. La cometa dista dalla Terra 300 milioni di km ,la nebulosa gufo invece 2600 anni luce(ogni anno luce corrisponde a 10.000 miliardi di km) , mentre la galassia dista piu di 45 milioni di anni luce! Sono presenti anche galassie distanti 700 milioni di anni luce, appena visibili. La foto è il frutto della somma di 15 pose da 2 minuti a 400 iso fatte con una Canon 700d e un telescopio 200/1000

Messier 108 (M108), nicknamed the Surfboard Galaxy, is a barred spiral galaxy located in the constellation Ursa Major. The galaxy lies at an approximate distance of 45.9 million light years from Earth and has an apparent magnitude of 10.7.
Tech Specs: This image is composed of 27 x 60 second images at ISO 3,200 with 5 x 60 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Guided using a Canon 400mm lens and ZWO ASI290MC camera. Imaging was done on February 26, 2017 from Weatherly, Pennsylvania.
Planetary nebula, M97, and spiral galaxy M108, in the constellation Ursa Major, are separated by only 50 arc minutes in the sky. This proximity allows them to be photographed in a single frame using a small to medium size telescope. M97 is commonly called the Owl Nebula, while M108 is called the Surfboard Galaxy, but I can't help thinking of them as the Owl and the Pussycat, after the poem by Edward Lear.

This image from Ursa Major shows two Messier objects in the same field. They are 48 arcminutes apart. Many of the small background "stars" here are actually distant galaxies.
The Owl planetary nebula is about 3.7 arcminutes across in our sky but is actually 0.91 light years in diameter. It lies about 2600 light years distant. The central star has shed its outer layers which glow either red (hydrogen) or green-blue (oxygen) lit by the light of the remnant white dwarf star. Eventually, the star will cool and the gas will expand until the nebula fades away.
Barred spiral galaxy M108 is about 45 million light years away and is almost edge on from our perspective. It’s 8.7 x 2.2 arcminutes diameter in our sky. It lacks a prominent core or bulge but has numerous dust lanes. A Type II supernovae was observed here in 1969. It’s possible to see brownish dust lanes, pink hydrogen alpha zones and two bright blue stellar “associations” of young stars at this magnification.

Had some problems with this - although guiding parameters were excellent, I've got some trailing which might be due to differential flexure - my guide scope is comprised of a main tube, coarse focuser and helical focuser and there was a bit of loose play at each junction. Have tightened the grub screws up and will make sure scope is tightly aligned with main scope.
Secondly, Ive got red haloes around the bright stars - not the blue/violet you would expect with a doublet scope - the last time I had this problem, it was due to a IDAS LPS D2 clip in filter. I usually use the D1 version without issues. Funny that it has resurfaced with the 2 inch D2 filter currently fitted in my field flattener - think it will have to go!
Can fix these with a little bench work I hope.
