Modern imaging

Ah?....yes, still fiddling around with this data

Here is an interesting comparison to show what a 6" F7.5 telescope can do today utilising modern imaging equipment and processing compared to a 1.2m F2.5 astrograph and photographic emulsion a generation ago:

Qudos to him for how far ahead of the World Dr David Malin was at the time that he could extract such faint data from just a 70min exposure!

That's quite a comparison Mike, we truly are blessed with modern technology.
I know your equipment wouldn't come cheap but compared to a 1.2m monster...

Hmm...So I wonder how many years before Skywatcher release thier "Hubble" range of remote telescopes?

Very interesting comparison indeed....

And dont worry about continiously posting that shot, Mike, I think I love that image about as much as you do

About $30K all up for scope+mount+camera etc at 2009 replacement prices (sheesh!..it adds up! must remember for insurance!) compared to AU$16Million (in 1973 $'s)

Oh my gawd not another Cent A image??!! Hehehe

Time to get out and do a fresh 20 hour image Mikey boy.

Greg.

AlexN · #8 26-03-2009, 05:03 PM

I vote for 20hrs on M16.... Ha.S.H.O for LRGB!

my 2c..

Its ok Mike I havent seen it, so thanks for re-posting

That truly is an amazing image, I love all the little galaxies in the back ground...

When I first started at CSIRO in 1974 my immediate supervisor explained to me about this Malin bloke that made out of focus masks to modulate the image on the very large plates from the Anglo Australian Telescope when he 'printed' them to tease out low contrast detail and still attempt to get the full dynamic range. This very bright scientist was Peter Tulloch.

We all think we live in a golden age of discovery. The reality is we should do the best we can with the equipment we have and also realize any shortcomings in ourselves and the equipment.

We should all take a moment to contemplate all the people who came before us that spent their lives showing us the way.

All scientific endeavour depends on so many people and good equipment before we even have a good idea, so it is difficult to excise your original contribution from what is already known.

Yes planted by throwing them out the window and three days later that galaxy stalk grew

Ah...yes!

I know

I sit here playing quite often and just fiddle, every now and then I throw something together from old data that I think looks kinda cool so I post it, not a Eureka moment just different usually.

Ah yes Alex quite a possibilty, my new low reflection Astronomik LRGB filter set arrives next week so I will be out ASAP

...really trying to decide on what to do, I have so many ideas

...err?..maybe Centaurus A...?

Glad for ya Jay, did you have a browse at the full colour version and other versions of the data?...I did a few

Now I think there is a cryptic message in there somewhere Bert...sooooo can ya enlighten me, please? In laymans speak, I am after all an ex strongman

Love the two comparisons Mike

jase (Jason) · #13 26-03-2009, 07:30 PM

I like this comparison Mike. Its appropriate given the work you've put into it. Now if only you could convert the time you've spent reprocessing your data into image acquisition... Hope you get some clear skies soon mate, I want to see some new targets.

Garyh · #14 26-03-2009, 07:49 PM

Yes, very interesting comparison Mike. Shows how far we have come in such a short time. I would love to see a picture of this done with a 6" scope back in the 70`s compared to the 1.2m scope today! Now that would be a shocker!
cheers
