Spectacular images. Thanks for sharing Paul.

Not Hubble images, but check out some of this guy's photos. He
attaches his 20D to a telescope mount.

Wow....they truly are amazing. At 1600 ISO, the 20D continues to
impress. Thanks for sharing Troy.

To be fair, he does take multiple long exposure shots and sort of
stacks them, running them through some software that removes
noise. Still pretty impressive what you can do with a dSLR and
telescope mount.

What is most impressive to me is that he is doing this unguided. With no
dark frames or Flatframes.

I've been doing this for a few years and have yet to get to that level and
I have very similar equipment.

There seems to be lot of 'illumination' in these pictures
(i.e. - an awful lot of photoshopping).

You wouldn't think the Triffid shown here
http://img.dailymail.co.uk/img/galle...10_350x301.jpg

Has much in common with these other Triffids -

At least the sombrero retains a bit of resemblance to its 'before' image:

After a while I am not sure at all what these things really look like.

Not sure what you mean about dark frames or flatframes. IIUC his
mount turns the camera with rotation of Earth, so no star trails
etc. It tracks for him, allowing crisp stars. The software he
uses takes the different shots he has and removes noise and
brings out detail in the nebulae and fainter stars.

If I come across the link he posted for the software he uses I'll
let you know. Think it was a whole bunch of PS actions that some
astrophotog had put together for enhancement, but it's commercial
not free.

I've been doing this for a few years and have yet to get to that level and

Some nice shots there. Particularly:

Some of the others seem noisy and/or soft?

Dark frames are a way of removing noise from an astroimage. It is an
equivilent length shot as the light frame, just with the lens cap on so all
you get to measure is the noise in shot. this is then subtracted from the
light shots.

A flat frame is short exposure with the camera in the same orientation and
focus to the telescope and shot against a netural background. This is to
used to help remove dust and vingetting and other issues in the optical
train. Again it is used in conjunction with the stacking SW. The Noel
Carboni's Astrophoto tools are a set of actions in photoshop that help in
post processing. They cost about $20.00 and I own it also.

There are many stacking programs available, Registax, Deepsky Stacker,
Images Plus, Registar, etc.... I like Deepsky Stacker. It is free and works
great.

He has a Losmandy G-ll mount and yes it does track the stars. I have the
same mount. Guiding is used to adjust the mount tracking to seeing (the
minor variations in tracking due to atmospheric turbulence, and slop in the
mount's accuracy.

Thanks, I try but I'm an amateur compared to him.
