Deep Sky Astrophotography
« on: April 08, 2014, 12:17:35 AM »
The other thread ended up with a bit too much discussion on the topic of astrophotography and the related gear. Figured a new, clean one, dedicated just to the imagery, would be good.

Please, feel free to share your own images as well! (If you already shared some in the old thread, maybe re-share them here, hopefully we can keep this topic free of astrophotography gear and technique related discussion, and just keep it on the images.)

Here are some of my images, produced with some dedicated astrophotography equipment (german equatorial tracking mount, or GEM, guiding telescope and camera, etc.) All of these were created from mid Feb. 2014 through the end of March. 2014.

Star Clusters
The Pleiades (Seven Sisters), in Taurus:

Original Attempt


Second Attempt (deeper exposures, softer detail due to tracking issues)

M35 and NGC2158, in Gemini


Nebula
Horse Head and Flame Nebulas, In Orion:


Orion Nebula (M42 & M43) and Running Man, in Orion:


Rosette Nebula, in Monoceros (Unicorn):

Original Processing


Reprocessed in PixInsight

Galaxies

This is incredible stuff mate, I’m dying to try this genre of photography, but last time we had no moon (last weekend) there was a sand/dust storm and the sky was obscured.  >:(
The image of the M101 galaxy is stunning, could you share how you achieved this photograph?  I would love to have a bash! 
Ohh, I have the Google Sky Map app on my phone, so I can at least spot the general direction of the galaxies etc!
Thanks in advance.
70D - 100-400L - 24-105L - 50 f1.8 II - Sigma 10-20 f4-5.6 - Sigma 610 ST.
Next on the hit list, and in no particular order -  1.4xTCIII + 2xTCIII + 100 f2.8 USM macro + 430 EX-II

@TheJock: Check out the other thread. I've provided a lot of information on the kind of equipment you'll need to get started. We can continue the discussion there.

We finally had a couple of clear nights the last two nights here in Colorado. These are the first since the lunar eclipse some five weeks ago now. Gave me the opportunity to image part of the North America nebula in Cygnus.



Equipment:
- Canon EOS 7D (unmodded)
- Canon EF 600mm f/4 L II (image)
- Orion ST80 (guider) + SSAG

Integration (49 subs (3h 40m)):
- 52x270s (4m30s) (95% integrated)
- 67 Darks (divided into three groups, temp matching lights, ~15-20 darks per group)
- 100 Biases
- 30 Flats

You've posted some incredible photographs!  My favorite is the horse head nebula.  Bravo and please post more when you can.

Living up in the Northwest, our availability of clear weather is limited to the summer, and then we have a lot of light contamination from Spokane, starting about 10 miles South of us.  We are in the country, as far as the neighborhood, but not away from the city light.
 
I've been up in Northern British Columbia, 100 miles from anything but tiny villages, and its truly amazing what you can see on a clear night.  Astrophotography would be a great hobby up there.

Light pollution doesn't have to be a problem these days. I actually shot this only a few miles from Denver, CO. The trick is using a light pollution filter. They don't work as well for galaxies (which are mostly stars, so broad band emissions), but for nebula (which are narrow band emissions), they work wonders. I use the Astronomik CLS, which is one of the better ones for blocking pollutant bands.

All of my images were shot under light polluted skies using the Astronomik filter. I'm under a yellow zone that, depending on the atmospheric particulates, often turns into an orange zone (I generally judge by whether I can see the milky way or not...if I can faintly see it, then my LP conditions are more yellow-zone, if not, then orange zone. Either way, with an LP filter, you can image under heavily light polluted skies. I know many people who image under white zones.

I agree, though, it's amazing what you can see under dark skies. There is one spot in the north western corner of Colorado that is 100% free of LP of any kind. I want to get up there sometime and see what it's like. You can very clearly see the milky way, so clearly that all the dust lanes show up to the naked eye, and all the larger Messier objects (like Andromeda, Triangulum, etc.) is also visible to the naked eye.

Jon,

Absolutely astonishing work.  I am cuurently vacationing on a small island in northern Fiji and wish you could all experience 0 LP.  Its amazing what the naked eye can see.  Unfortunately my hard drive died so I can post photo,s.

These are amazing.  I'm jealous.  Gonna try my hand in a big way tonight with a large telescope (60 cm - professionally guided, Mt. Wilson Observatory). We were planning on shooting planets with the 1DX and deep space 60a.  Any extra advice would be helpful.  (I've read alot over the last few weeks, but always need to learn more)

Thanks, guys! :)

@Kahuna, I bet the sky out there is AMAZING! I'm quite envious. I barely remember dark skies as a kid, when LP was much less than it is today, and when we lived pretty far out of town. But I wasn't as observant of the details back then. I really don't even remember what the summer sky milky way looks like under a truly dark sky.

Even if you don't have a camera, you still have eyeballs and a brain! Remember those nights! :)

As for advice, that is probably best left for another thread. Start one, PM me the link, and I'll offer the best bits of advice I have.

M109 in Ursa Major, most distant of the Messier objects.

First try with PixInsight, I've been using Deep Sky Stacker & PhotoShop for years, but a trial download of PixInsight converted me pretty quick.  I recently revamped my old imaging laptop (Vista) with a SSD and a new video cable for the display and installed AstroTortilla on it.  Confirmed AT works fine with some archived images....but don't you know we have a week of rain coming at us.  I'd rather subject that laptop to the elements than my i7 Win8.1, which is now my image processing platform so my son can have his desktop back.  I like my Newt and SCT's, but the only 'refractor' I'd be interested in is that 600/4L.  APO's are nice, but you can't shoot BIF's with one.....

Superb image of the North America Nebula! (NGC 7000) But could you explain how the nebula "looks" like the continent? ??? Because I can't really see any resemblance between the 2.
