Space From My Backyard: 38 Pictures I Took With A Telescope

Yes, it’s a reference to the designation of this object in the Messier astronomical catalog. The catalog was compiled by Charles Messier in the 1700s.

This particular setup I’m using now, if I were to buy everything new would cost around $7500. I bought a lot of used products and did it modularly as to not incur the financial burden all at once. I began with much simpler gear which was a lot more inexpensive. Depending on your goals, you could get a decent setup for around $2500-3000. For nightscapes with the Milky Way as a background, a good DSLR and a star tracker is about all that is needed.

I’ve never noticed that before!

Thank you! Not as much total time as I’d really wanted but here are all the image details: - H: 54 x 120” (1h 48m) - O: 86 x 120” (2h 52m) - S: 62 x 120” (2h 4m) - 6h 44m total exposure time - Celestron 8” SCT - Celestron CGEM II - ZWO asi1600mm Pro - Svbony 60mm guide scope - ZWO asi224mc (guide camera) - ZWO AsiAir Plus - Celestron 0.63x Reducer/Field Flattener - Antlia 3nm narrowband filters

Thank you! I use software called Pixinsight to do all of my post-processing. I use a mono camera so I start with 3 different images, one each for hydrogen, oxygen and sulfur on narrowband targets. I remove the stars from each and colorize each channel typically mapping the colors in a SHO palette which is sulfur to red, hydrogen to green and oxygen to blue. From there it’s minor curves adjustments and color masks and light stretching and then add the stars back in. I need to do a YT video on my process!

Most all of these were taken with an 8” telescope and a dedicated astronomy CMOS camera.

For visual use, the Celestron Nexstar 8SE is a great choice and not difficult to use. It includes an alt/az mount which makes things easier than an EQ mount as I’m using here which is necessary for long exposures to prevent star trails and field rotation. GoTo functionality is nice on it as well so you can easily find objects in the sky.

Thank you very much! I feel the same way about our place in the cosmos. Carl Sagan once said astronomy is a humbling and character-building experience and I couldn’t agree more!

I never realized how ridiculously some of these are named. Did they run out of cool names and just start using random things they saw? Am I gonna see the Starbucks Coffee Cup galaxy soon?

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Seriously? The vacume cleaner galaxy? I can hear the conversation now... So I'm named Thors Helmet! How about you? I'm named the Wizard Galaxy! You in the back, what are you called? The Vacume Cleaner Galaxy. Ohh....well I'm sure you're a perfectly nice galaxy.

I don't really see a lion but just left of center it looks like something is emitting light beams.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

"Stunning" doesn't come close

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Actually, their parallax indicates they may not be. Still beautiful to look at though!

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Think for a moment. Galaxies have billions of stars. Those stars have Goldilocks zones, and some have planets in said zone. Those planets may host intelligent life. Anyone who thinks Earth is unique in the fact that it has life is selfish. We have proof that small bacteria used to live on Mars even!

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

I wish they would turn them down at night but nope, they are too busy with vanity projects.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Wow, this is terrific !! Pillars of creation in the middle is almost like Hubble image. Can you share information about integration time per filter (SHO) and your telescope? Thanks.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

I love how many times you see this beauty tagged as the Milky Way. Far out camera man.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Thank you for the info!

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

David, how do you do the enhanced coloring? Your photos are just gorgeous. My husband has been doing this out in our front yard all summer.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Cool. That makes more sense. It looks just like the Hubble image!

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Will bp ever get rid of people like this

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Fun fact: in finnish, nebula is tähtisumu- literally "starfog"

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Reminds me of a heart

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Beautiful. And you can see the Pillara of Creation in the middle

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Unlike most of them, I see where the name came from.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Is that telescope very difficult to learn to use? My siblings and my parents have been wanting to get a decent telescope for ages, ever since the 'rents got a property up in New Hampshire. The sky is so clear up there.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Such amazing pictures... Thanks for sharing! Sometimes it is intimidating how small the earth and us humans really are in the universe...

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

I see a giant owl here... Now maybe I'm a bit biased cause I like them a lot ^^"

Thanks so much! I’m working on a close up portion of the Heart Nebula now (the fish head)

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Thank you so much! I understand, my skies aren’t great so visual astronomy is almost impossible here, long exposure photography with narrowband filters is my alternative to combat light pollution.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

The vacuum cleaner galaxy is my favorite name I think! There’s one called the blow dryer galaxy too, I’ve just never imaged it before.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Thank you!

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

Yes, I used 3 filters to pick up specific wavelengths - Hydrogen Alpha, Oxygen III & Sulphur II gases. Without filters, the color in this particular nebula is reddish/pink.

I Enjoy Taking Long Exposure Photographs Of Deep Space Objects, Here Are 22 Of My Latest Images

That’s such a shame, I wonder if the local government there would do anything about all of the unnecessary street lights.
