This post has me reminiscing. Remember the comparison photos that Irwin once posted, one of his Mars images and a Hubble one? Extraordinary. Makes one wonder what he would be producing with today's technology.
(sorry to hijack this thread btw)
Get well soon Mike.

Hi Jeanette
I assume you mean Erwin van der Velden?
No I didn't see them, where is Irwins image, love to see it if it is still on the net.
No Hijack here

Mike, I distorted the pic a bit to de-ovalise a couple of stars. The main experiment was to change the colours on your (middle ) image.

Oh ok. Gee I thought it was a a totally different image...you murdered it man
I did this imge back in May 06, at that stage I was imaging with a Starlightxpress camera and True Tech filterwheel. Unfortunately the internal filter wheel disc was not orthoganal to the optical axis and it sloped a bit which sometimes caused oval stars, in this case I had a bit of tilt in my Ha shots which was why I added the Lum and Red to the Ha, this helped reduce the ovalisation but did lose a bit of resolution because the Lum and Red data isn't as detailed, still, I was happy with the final outcome.

What a fantastic comparison! Thanks for that great image Mike. You are right, it does make you notice things you would otherwise miss...

A few facts to consider here;
Image on the Left Image on the Right
Author: Mike Sidonio (Aus) Hubble/Nasa/ESA....US etc
People involved: 1 >5000
Aperture used: 150mm & 80mm 2400mm
Weight: <100kg (scope, not u) 11,170kg (11 tonnes)
Speed: 0 km/h 27,000 km/h
Technology: Refractor & CCD RC Cassegrain & WFC
Altitude: <500 metres >559 Kilometres
Cost: <$15,000USD? > $2.5 BILLION & counting
Launch Mechanism: Mike (and car) Space Shuttle Discovery
Propellant: Beer Liquid Hydrocarbon
Comparison between the two images: PRICELESS
I for one, enjoyed that comparison, a lot.
Thanks Mike, its amazing just how much you can see and capture from EARTH compared to a MULTI BILLION dollar project that probably no one we know will ever get to drive themselves.
Astronomy is great, aint it?
Cheers

That's what I was thinking as well Humayun. Very good shot Mike.

Very funny Chris
The Hubble ultra deep fields alone have been worth the 10's of $billion spent so far though. The idea of staring at the same tiny area of sky for days or weeks at a time to peer farther and farther back in time so that what would otherwise be a pretty empty piece of sky from Earth becomes full of thousands of remote galaxies forming just after the Big Bang...is certainly priceless
Arrr chooo...sniff sniff hack...

Not that comparing ground based data with the HST is ever going to be fair, but I also figure you need to give the HST people their due and at least compare data at the same res as the Hubble shot....ie don't down sample.
This roll-over keeps the HST data in its native res...

Hope your cold gets better soon Mike.

Now THAT'S a true "fickle finger"
Great comparison Peter wish I could do roll overs on my site, very cool.
Makes it easier to find the details in my version...isn't Hubble the coolest scope?
Yes hope I get better soon too, I am sick of coughing up Freds narrow band images

With Hubble's servicing mission 4 completed, future HST imagery should be
decidedly more spectacular as the new Wide field camera 3 was installed..being several generations ahead of the camera used for "that" M16
image.
What does the WFC3 look like?

(Just a little bigger than the new camera I'm expecting to arrive in a month or so  )

Ah yes, receieving a big new camera in the mail is very exciting!
