Messing with deep sky

Night time stars and sights have always held a fascination.
It was finally time to mess around with it.


Curiousity got the goat one night, and I fired off at the ISS.
Canon 5D MkII, 100-400 f/4.5L at 400mm, 1/180 sec, f5.6, ISO 1000
Solar panels are visible, as is the main body. Supporting truss is not visible.

Major cropping involved. In original, ISS was just a dot.

Orion rising in the trees. Minor cropping of image.
Same body with 100 f/2.8L 30 sec., f/4, ISO 640
Camera attached to tracking mount.


Orion nebula. Medium cropping.
5D with the 100-400 again. 30 sec., f/8, ISO 3200
Tracked of course.

1. Amazing.

 

I had no idea you could do that much without an observatory full of equipment.
I had a 3" Newtonian reflector when I was a kid, but I never tried taking pictures through it.

3. Your turn

 

The NEX can do much the same. You just won't have quite the "reach" until you aquire a new lens.
Set it up on a tripod and fire away with what you have.
Wide angle sky shots have a beauty all their own.

4. Absolutely

 

They're a must have with any long glass.
I'm just using a CG-4 with a battery powered tracker.
Still trying to work up the nerve to start hitting minute or longer shots.

5. Love

That last shot!!

This is something I would like to try at some point, although I'll have to get out of the suburbs of Boston and the light pollution.

I remember as a kid in Maine getting home on crystal clear nights in the winter with the Milky Way visible stretched out across the sky. Just Beautiful.

Fantastic shots and thanks for posting.

6. Couldn't help it

 

Moon was so darn pretty the last couple mornings, I decided to hit it.
Tripod mounted of course.
5D with 100-400 at 400 with a 1.4x TE (560mm equivalent)
1/8sec; f/11; ISO 100
Stack of four, with Registax 6, then cropped.

9. Poor damn goat

 

He's still not safe.
The last five days, I've been hitting the moon every morning at the same time.
The idea is to follow the terminator as it moves across.
Kind of a pain cause I shoot at least fifty eac time, then cull through them for a couple good ones.
I'll try for a sixth series tomorrow, then stick the final six in here.

Bad part...
Jupiter popped up and I couldn't resist going after it to see what I got.
Took fifteen, and this turned out best.

Same set-up as used with lunar shots.
All four major moons are visible.
Callisto is the "attached" dot sitting at the nine oclock position of Jupiters limb.
At the seven oclock position and down, are two dots. The upper is Io, and the lower, Europa.
Further down from them, is Ganymede.


This the full frame (reduced in size to fit in here), prior to zooming.cropping.

10. What a pain

 

Took far longer than I thought it would.
Ended up with seven days of lunar shots.
Starts the morning of the 7th and ends the morning of the 13th.
Some mornings were good, others, not so much.
I learned a little from this excersize.

12. Great shot of the ISS.

I've been watching it pass all week here in NE Ohio where evenings have been clear as a bell. I tried looking through binoculars, but they don't help much. It's too fast for my telescopes.

Thanx for posting!

14. M31

 

Ran some 30 second shots toward M31, a couple mornings ago.
Stacked three and tweaked to result. Cropped of course.
M32 and M110 also showed up.
3x30 sec. 185mm f/5.6 800ISO

15. how dark is your location?

how hard was it to point the camera at m31 since you reallly cant see it in the viewfinder

16. educated guess

 

I know where it is, and point the camera as close as I can.
Take one test shot, check screen, then adjust to get it closer.
If you saw the full frame, M31 is considerably smaller than in the image I posted.
Due to light pollution, Mag 3 and sometimes 4 is about as good as it gets.
I can get Mag 5 if I drive north 30 miles.

17. Just an update

 

I've found that exposures over one minute will require a tracking scope.
Did a few longer runs and saw the star images start to football on me.

I did find out that I can get down to the 14th magnitude (sort of).
Now, the mission is to image Pluto, with a 200mm lens.
Got my doubts, gotta try it.

BTW, I have done this with a old Sony F717, mounted afocally on a large SCT telescope.
