| The telescope i used has a color camera, so i just input the exposure time and amount of frames. Very easy to do, and there are some video tutorials on the site.
You get 50 points i think for the free demo and another 30 points if you pay 5 aud for the extended demo that gives you access the raw data, so you can process the images properly. Better telescopes (with filters ect) cost more points per hour. This one is 4x300s and the cost was 16 points so there's some noise in the darker parts. The nebula was at the edge of the frame so i complained and got a refund :P Still managed to squeeze a nice picture out of it.

| Would it be possible to photograph the Cat's Eye Nebula with a 75-300mm lens (f/4-5.6) and no equatorial mount?

| I doubt you could get any hint of it without tracking. Its a very small nebula, so even on a tracking mount it would appear star-like on that lens. You can try shooting comet C/2014 Q2 Lovejoy while it's near Polaris. When shooting near the celestial poles you won't need a tracking mount to get a long exposure whit minimal star trails.

| In short, yes, but don't expect it to see much of its structural detail.
Your biggest challenge is that the Cat's Eye is very small: the brighter central region of it is only about 20 arcseconds across, versus 36 arcmin for Omega Centuari. Even going the full 300mm, it's going to be about 1/100th the size of your earlier capture of Omega Centauri.
On the positive side, even though the Cat's Eye is fainter (~8th mag vs 4th for Omega Cen), its small size means it has much higher surface brightness (by about 40 or 50x). So it should be visible, if even as a fuzzy star-like object.
If you try it, use the same method as before: high zoom, high ISO, longest exposure you can without trailing, and stack a large number of images.

Ah, i missed the earlier shots. Well you can definetley get it, but as Watsisname said, it's a small target for an 300mm.

| I made this video that basically showcases areas around Cornwall, under the night sky, as well as a narrative I wrote (apart from the ending Carl Sagan quote). The audio isn't as good as it could have been and can be a tad quiet but it's not too bad.
After finishing this video and then calculating all the mileage I traveled for the different areas, it turns out I traveled around 750 miles!  A few of the locations come with a story each, but maybe that's something for another time

| Here's another photo from itelescope.net The North America and Pelican nebulae.
This time i used telescope t20 which is brighter and has lower magnification so seeing is not an issue and the image is very sharp. 300s through Red, Green, Blue, and H alpha filters. And I've ran out of points so i might be buying a regular membership later.
I'll use these to make models for Space Engine.

OMG It's... awesome 
Why don't you do a stream on YouTube/Twich and we go through the universe all together?
The universe is not required to be in perfect harmony with human ambition.

| astroniki, this makes me speechless. 
Unrelated, did anyone else get to see the aurora last night? We had quite the geomagnetic storm, and from here in Washington the lights were very bright, shifted rapidly, and sometimes spread past zenith. Probably the best show in this area in many years.

| Over here the northern sky looks like this at midnight these days...
Perhaps, using photography and clever image processing, it could be possible to extract some aurora from the southern sky if present there even with the sun 6 degrees below the horizon, but I doubt it.

You can't see images like that in real time. This is the result of many long exposure photographs composited together. Whatever might be visible in real time would be nothing more than a faint gray smudge with some stars.
Amazing image Astroniki!
And cool aurora images Watsisname
