View Full Version here: : Clear Night of Video Broadcasting (Astrocasting)
29-01-2011, 09:50 PM
Last night was the first clear night in ages, and the boggy water-logged back yard has dried up enough to support the mount again, so I had a night of Astrocasting again.
Been months since my last broadcast.
I started the night with a 16~160 lens from Bert (Avandonk).
I had to fit an IR/UV filter inside the lens as the stars were horrific.
Last night was the first chance to try it out.
The stars were markedly improved but I was having trouble picking up nebulae.
I have to learn which settings work best with this lens.
The 1st image in the collection below is with the 16~160 lens. See how faint Tarantula is.
After unsuccessful attempts, I switched over to the Saxon 120mm f5 Achromat Refractor with a 0.6x Focal Reducer.
All the other images are from the Saxon.
Every image is a screen grab of live video. No stacking, No processing. Just a single screen Grab.
These give a great example of what you see on screen doing 'Live' Video Astronomy :)
Camera used: Samsung SCC-A2333P

and one more for the road. :lol:
Also a look at what I see across 2 monitors when Broadcasting 'Live' on the net :thumbsup:

Lovely work Ken,
Good to see someone is out under the stars.

Everytime I look no one is there :( must go to bed too early :D

:lol: Yeah, because it is world wide it helps to know when people are actually broadcasting.
In the last image above (my monitors) you can see I have the time for several places around the world. That way I know when people are likely to be broadcasting.
Americans tend to broadcast in our mid to late-afternoon, Poms in our Morning.
If I want to watch Martin (MLyons) in South Africa he comes on around 6am our time.
When I broadcast at night the Americans are just getting up and the Poms are having afternoon tea :lol:
By the time I finish broadcasting in the wee hours the Americans have all gone to work and the Poms are coming home from work :rofl:
It's all a matter of working out when people are likely to be broadcasting in their night-time.
I seem to be the only one broadcasting in our night-time, except for the occasional American Solar broadcast.

astrojunk is live now
29-01-2011, 11:24 PM
Going to watch and chat. :thumbsup:

Jonathan (astrojunk) put on a great show :thumbsup:
Glad to know I'm not the only Aussie in NSN (http://www.nightskiesnetwork.com/).
Martin Ferlito up in Sydney used to do a bit but he seems to have stopped.
Hopefully Bob in Melbourne might be in there soon, and Tony (that_guy) is setting up ready to start soon too. :)
and there's also Martin Lyons in South Africa :thumbsup:
We need more Aussies and other Southern Hemi's broadcasting in NSN to show the Northern Hemispherians what REAL sky looks like :lol:
Looking good Ken.
The camera picks up a lot of faint fuzzies.
I see if i can finally start broadcasting when i have build my obs.
Cant image and broadcast at the same time at the moment :(
30-01-2011, 06:48 PM
Yeah, I pointed at the Centaurus Galaxy Cluster and saw approx 25 little galaxies in the FOV 'live'!!!
Now that's a buzz :D
30-01-2011, 07:23 PM
I have a channel, but not broadcasting, not sure anyone wants to see an unfinished Obs LOL
30-01-2011, 07:43 PM
I have watched broadcasts of blokes showing their equipment. :thumbsup:
I did one of watching sunset over Snake Valley.
30-01-2011, 08:43 PM
Great stuff Ken. Looks like you are having some fun. Maybe able to image tonight if I am lucky.
30-01-2011, 08:57 PM
That's the amazing thing about Astrocasting. It's actually FUN :)
Probably because the images are 'live' and the site is interactive with the viewers :thumbsup:
30-01-2011, 08:58 PM
I had a great time when I was on Ken.
I can really see why you're so enthused.
30-01-2011, 09:06 PM
Get back into it jj.
You have all the gear ;)
30-01-2011, 09:22 PM
Thanks Ken, it was fun to chat with you and the NSNers. We will have to setup an alert mechanism somehow. Maybe something as simple as a post to a standard thread here on iis would do it?

How much bandwidth does it use, say, per hour?
My kids eat me out of house and home by watching Youtube. Don't ever want to get slowed to 64kbps again.
30-01-2011, 09:36 PM
Hmmmm . . . I don't know jj.
I just use it without fear of running out of Bandwidth coz I have 100Gb a month, and with all 4 of us using You Tube (one son heavily), surfing, Cheryl and my other son playing online games, and me broadcasting (up to 8 hours at a sitting), we still only use about 10% of our 100Gb allowance.
I've never checked how much broadcasting uses up. How would I find out?
30-01-2011, 09:38 PM
Yeah, I've been thinking about that.
Not sure how. :shrug:
31-01-2011, 09:08 AM
Ken used my wireless internet last camp. He used over 1 GByte during that time - was that 3 nights, Ken - about 7-8 hrs per night?
01-02-2011, 01:15 AM
Yep, that's about right Eric.
I am broadcasting right now if anyone wants to drop in and have a look and a chat: http://www.nightskiesnetwork.com/live/channel.php?n=Snake%20Valley%20Aust ralia

Mind you, if your ISP gives you free upload (any of those still around??). you're laughing!
01-02-2011, 06:28 PM
Thanks Jeanettie and all the others that dropped in during the very early hours of this morning during my broadcast.
It got quite crowded in there for a few hours with all the regular viewers from Australia, USA, Canada & UK, plus some folk from in here, and Jeanette and all those she invited in from Facebook :lol:
Had a great time looking at some of the same old regular objects (but the Northerners love seeing them :) ), then some new objects, then I started showing objects and the viewers had to guess what they were :lol:
Was a great night. :thumbsup:
And all 'LIVE'. :)
01-02-2011, 07:25 PM
I had a ball Ken. Looking forward to next time. :D
05-04-2011, 10:15 PM
I am 'live' on air now if anyone wants to drop in and watch and say hello :thumbsup:
Look for Snake Valley Australia :)
06-04-2011, 09:33 AM
Sorry I missed it Ken. I've had to pull out of broadcasting myself because I can't abide to their terms and conditions :(

Last night was finally clear until a fog rolled in at about 3am.
No wonder my on-screen live views were starting to lose a bit of quality by then (it shows in my Eagle Nebula pic).
But up until then it was a great night with a whole bunch of great targets and great people dropping in. Thanks
This was the first real chance I have had to test out Bert's (avandonk's) Skywatcher 6" f5 Achro with my Samsung Camera.
It sucks in some good light
Out of the few Screen Grabs I remembered to get :P I got some fairly reasonable ones, all with the 6" f5 Achro, 0.6x focal reducer, modified Samsung SCC-A2333 camera, all up on an EQ6 mount.
All are single 10 second integration Screen Grabs from live feed during my NSN broadcast last night (NO post-processing).
They are all great examples of what you see 'Live' on the screen with Video Astronomy.
Time to throw away all those EP's and see objects 'live' in colour :lol:

Gosh, I've had to register! Getting formal now. But no-one online. .................
UPDATE: - Ken's online! :thumbsup:
