I've been messing about with telescopes for about 40 years.
Started out with a home-buit Newtonian - great scopes - you can spend half a life-time tinkering with those.
Never heard of video astronomy until about 7 months ago when I came across some of Ken's videos etc. Got hooked.
Up till now I've used a Revo Imager (ICX811 chip). I'm still amazed at the views I get plugging my 5" Bresser into an old, but pretty high end. Sony analogue TV.
A week or so ago I bought a G-Star Ex-3 digital camera from Steve Massey. If the clouds ever go away I'll post some pics.
A lot of generous people on this an other groups have helped me spend money and become a happier man.
I hope I can give something back now that ChrisV and Davy have sorted out my log-in problem.
Cheers Robert

Davy did it. So welcome at last !
It'll be really interesting to see how the G-Star compares to the ZWO224MC. Especially given it has a cooling fan.

I too am anxious to see the results! Thanks for hopping on board, Robert! Glad you're getting enjoyment out of this part of the hobby!

Thank you all.
Seems I screwed up my first post.
I'll try to put the next one in the right place...

G'day Robert, welcome mate, and thanks for the comment on my Videos Much appreciated. I am also waiting to see what the new Gstar-Ex3 can do. I listed it for Steve on my Video Astronomy website on the equipment page HEREand started threads about it in several Astro Forums. Anything to help a fellow Aussie and his business. I am interested in the new Gstar-Ex3, but don't have a spare $500+ to test one myself So I eagerly await reviews. Oh, and welcome to the world of Video Astronomy too

Thanks Ken
You're doing good things here.
Discovering video has allowed me to keep enjoying astronomy at a time when my eyes and back are not what they used to be.
I will get some grabs from the G-Star if that bunch of clouds that have sitting over Esk for the last month go away.
Kind regards Robert

Excellent Robert.
I'll be interested to see just how close to 'Live' the new Gstar-Ex3 can go. The demand for a real-time camera is high 'IF" it has good resolution. (WITHOUT STACKING) So far the cameras close to real-time have low resolution. And the cameras with high resolution don't do good realtime and aren't great on faint objects. The closest I have seen to real-time with a high res camera is one with the same sensor as the Gstar-Ex3 so things may be hopeful.
This is the one I mean, with the same sensor, and it is in real-time. Just very noisy, but it looks good. To me, this is real Video Astronomy observing:

That's pretty amazing. Which camera is that? Cooled?
I'm hoping to get out tonight and give the EX-3 a run.
My tinkering so far would suggest that the "live" part may be slow.
Hot pixels are a problem if you're chasing faint stuff which means (for me anyway) using the dark frame subtraction. This works very well with as few as 5 frames but there's another minute or two....

You should be able to do that with most any camera. On the 224 i just crank up the gain and use short exposures. Its also great for lining up objects before switching to stacking longer exposures

Ah.. f1.4 that makes life a lot easier.
That would be about 13x more light than my f5 - is that right?

Yup ... f5 ---> 5x5=25 and f1.4 ---> 1.4x1.4=1.96 and finally divide those resultants like this ... 25/1.96=12.75 times more light comes through f1.4 lens compared to f5 lens ... or to put it another way you can take each single frame with same overall brightness/data 12.75 times faster/quicker at f1.4 than at f5. ps ... retired engineer by trade LOL cheers

Thanks Howie
I used to do a lot of photography for scientific illustration back in the film days but it's all a bit dim now.

Any sort of decent go at photography would be a great background for EAA, won't be long and you'll be showing us all up! Can't wait to see your shots in a few months after you've "settled in" with the Gstar and its software.

Thanks Harry
Lousy weather at the moment - a balmy 39C (~102F) the last few days and cloudy as well.
So not much astronomy going on for me.
