Another HD HA Sun

[Peter Ward]

Sol in h-alpha on August 4th.... watch this space as I will likely update the image...the prom data is still clunking away but needs to be added...

the link is here (http://www.atscope.com.au/BRO/gallery114.html)


By the way... if you are getting of these constant solar posts, let me know and I'll ease up for a bit

Excellent, so much detail, keep em coming, always enjoy them.

[Peter Ward]

Thanks for indulging me Fred :)

Prom data is now in...you'll need to refresh your screen at the same URL :thumbsup:

[Bassnut]

whoa, that makes a big difference, even more excellent.

THAT'S WHAT I'M TALKIN ABOUT. Look great Pete. Love the colour and the proms are special.

Been at National Science Week (Science alive) all day today and was a day of solar viewing. I must have showed 100 people the sun in Ha. Lots of Wow's and then seeing this tops it off.:thumbsup:

Very nice work again Peter, I never get tired of looking at high class images of any astro target. Besides which the features on old Sol change often enough to warrant the creation of an ongoing record.

Thanks Trev.. Sadly work commitments mean a small imaging hiatus for yours truly..



Ta Paul, sounds like Science week was cool.

As for the image... dunno perhaps there is too much detail, and the red edge is distracting:question:....nah! :D

Your sun shots have a distinct pink-red ring around the limb, to me it doesn't look natural...or does the sun have such a distinct red limb I don't know about :shrug:

Lovely detail though

[Peter Ward]

No worries Mike.... the irony is the chromospheric edge is actually pink -red, it's the disk that I give the false colour treatment to.

The edge of the sun has a 3-6 arc second wide limb feature that looks rather like a "burning hedge". While I have seen this in a PST, 60mm or larger h-alpha systems show it quite well.

Another problem is the proms are significantly darker than the disk, something human eyes cope with well, but sends CCD's troppo.

So to convey all of the action on the Sun, I process the disk and limb quite differently. Some like it....some don't....either way I'm not phased.

Dunno why I am trying to help you with the colour. :P Your images already out gun mine by a reasonable margin when it comes to competitions. I should be trying to help make your images look worse. :lol: Yeah stay with pink brown mate. I was wrong, your colouring is right.:rofl:

Science alive for Science Week was cool. I woke up too sick today to go again but just hearing the wows when people took a look at Sol was a great feeling. Next year I am planning on using a big screen in the auditorium with the mount outside and having a live feed to the screen. People will really get a buzz out of that I reckon. Might do a solar physics thing too. I got a lot of questions about what caused sunspots and prominences and flares. Just a basic explanation with some diagrams should suffice.
