Was on NSN the other night and caught Abosze's broadcast of the sun. Now ive not seen many solar broadcasts but i thought this guy put on a great show of our own star He logged off before i could ask him if i could post a couple of screen grabs but im sure he wont mind. This is by far the most detailed view of the sun ive ever seen. Thanks Abosze!

Yes Chris, Abosze is a regular Solar Broadcaster on NSN.
I have been watching his broadcasts for about 2 years and he just gets better and better all the time. There are 4 top notch Solar broadcasters that I am aware of on NSN
Allan Bosze (Abosze), Gabriel Corban (uranus7), Craig Freeman (TacomaSky) and Rock Mallin (Mallincam).
Look them all up in You Tube, you'll be amazed!

Abosze is quite often online with his solar broadcasts, and he does a fine job with a dslr, but for the best solar casts going, you need to watch out for 'Tom(SoIN)'. He has the best quality scopes and the right cams for the job. His solar broadcasts are second to none. I would consider my casts worth watching too, but I can't touch Tom for equipment or the way he uses his software. His broadcasting is brilliant.

I do recognise a couple of they names will keep an eye out. And Allan im looking forward to catching one of your solar shows! Its something that up until recently i had no interest in at all... as i thought it was kinda boring with nothing to see. But seeing your guys results and conversations about it has intrigued me into finding out more about it. And it is quite fascinating!

I have never seen Tom do a Solar Broadcast. I wonder how I have missed that Allan, I forgot to mention your Solar broadcasts. Oops, sorry. I have probably forgotten some others too. There are so many people to remember.

Its like a lot of things Chris, you don't know whats there or how interesting it is until you take a close look. I was never much interested in lunar until I had a close look with a videao cam and saw some fascinating broadcasts. Now I can't wait for the moon to appear in the night sky. I certainly don't curse it anymore, I look at it with renwed interest. I don't rightly remember when I got hooked on solar imaging, but it was after I first saw some images in Hydrogen alpha. I couldn't believe what I was seeing and was bitten by the solar bug. I still meet folks who think astronomy is nerdy and boring, and is just looking at little stars. "ooh, how exciting" (yawn) They still have no idea whats actually up there that can be seen, especially with an astrovideo camera.
My solar viewing is a bit resticted at the moment, due the how low the sun is and how long its visible to me from my garden. In another few weeks it will clear the rooftops earlier and clear the pesky fir tree next door. Then I can have at least 2 hours around midday, everyday, whenever the suns shines.

No probs Ken, I didn't take it personally. I an surprised you forgot Derek Klepp though. he is the Gstar king of solar. You should see his images on the Gstar site. I don't think he broadcasts on NSN though, but is well known amongst the solar community. I would like to catch one of Gabriels casts if he does them. He produces some fine images too.

I've never heard of Derek Klepp. I'll have to Google him. Thanks Allan.
Yes, Gabriel broadcasts on NSN.

I've only looked through a solar scope once, at our own outreach session in a local park near me, they had to drag me away from it as the queue behind me was getting rather large, must say I was memorized of the view, it was a 100mm lunt which looked like it had some eyepiece thingy sticking out of the side if it, never knew what it was for

Great scope Johnno. That would have been the pressure tuner sticking out. You hold it and screw it in or out to adjust the air pressure in the etalon chamber. Varying to pressure alters the Ha bandwith and lets you see spots,(like white light viewing) filaments or proms, or even both at the same time.

Allan, do you have to pressurize the OTA or something before you can use it then, or am I totally off the ball park,

Johnno, solarscopes generally come in 3 flavours. Temperature tuned whereby the etalon is is heated to the correct temperature to bring it 'on Band' so that you can observe the detail that you want. Tilt Tuned, where you turn a thumbwheel or rotate something, which tilts the etalon and tunes it to the correct wavelength to show the detail you want to observe. Pressure tuned where you alter the pressure in the etalon chamber which in turn tunes the etalon to show the detail you want to observe.
Simply put, The etalon is a tuneable filter.
The OTA is not effected by any of this. It is the etalon component that is adjusted, and by adjusting it you can observe various details of the sun.
This is a very simplified explanation.
