Orion Nebula & Running Man 21/10/12

Tzetze

Got some clear skies Sat/Sun night/morn and had planned to target M42. Managed to get 11 usable subs before the fog rolled in. This is very much a work in progress. I'd intended to get some very short exposures to fix the badly burned out core - but that's going to have to wait for the next clear moonless night. Hopefully will get many more 600s subs too.

1h50m data
11x 600s subs
100x darks (Dark Library)
25x flats
450D CG5-GT SWED80 PHDGuided
Stacked in DSS, Tweaked in PS CS6

Wow, thats a beauty, even at this stage.

Really super pic.

Very nice. what kind of telescope did you use and eye piece?

Found my new desktop background...

This type of pictures is so way out of my league... thanks for posting it

^^ This. Nice work TzeTze!!

Awesome job man.. what ISO was that at . Also What is the effective focal lent of a SWED80 scope ?

Tzetze

Thanks a lot guys.

The scope is a semi-APO doublet refractor, 80mm aperture. Sky-watcher SW ED80 DS Pro. The camera is mounted where the eyepiece normally goes. However, to get that sort of field of view in an eyepiece, you'd want to use something in the region of 28 or 32mm.

That was ISO800. Scope is 600mm focal length.

Another top quality photo. Congratulations.

Tzetze,

I don't have a scope so forgive the dumb questions, to get that pic I thought you would of needed a bigger scope, Im surprised as I thought It would of cost €€€ more.

Why didn't you go for a bigger 8 or 10 inch reflector?

And what is the view of that picture like when you are looking through the scope? Is it tiny, can you see all the detail in that photo.
Sorry if those questions are a bit dumb, but the last time I looked through a scope i must of being around 8.


What would it look like if you used a scope in the 200/300 euro price range, would you be even able to see that part of space.

I started out with an interest in visual astronomy and picked up a second hand 10" Newtonian Reflector on a cg5 mount. It's a great setup for observing faint objects but the mount isn't suitable for using it along with the extra weight for AP. It is however, a great scope for AP on a heavier duty mount. Someday, I'll get it in action on a more permanent setup.

The photo above is a wide field of view - it's what the scope used is good at as it has a fairly short focal length - 600mm. The 10" reflector I have has a 1200mm focal length and a narrower field of view. Here's how the above target would frame with 10" scope and same camera. It doesn't fill the frame, whereas the image up top is a crop.

Visually, deep space objects will look nothing like the photos. You will see no colour. You'll need well dark-adapted eyes and very dark skies to pick out good detail.

For visual observing, aperture is king. Dobsonians are highly recommended for visual astronomy. Big aperture, low price. They are not suited to long exposure photography though.

Ah that's interesting, I really thought you could see the same but smaller, less detail, and in colour!

So it's really all about the camera, long exposure stuff.

Could you post a snap shot of what it would look like if you we're just looking through the scope.

Could you take a good photo like the one above of say Saturn or is it only for deep space.

Heres a youtube video.Its an 18" scope tho....

Another good page to see what could you expect to see :

What you can expect to see through the eyepiece. These are through the eyepiece on 8" - 12" scopes.

Planetary Imaging requires long focal length scopes with high framerate cameras (modified webcams are popular and give good results).

I feel sad looking at your first link............I was looking at getting a 8 inch scope these are with a 10 and 12 inch scope!!!


Second one give a little hope.



Cements my comment that you have top gear and great knowledge.
