Huge Solar Prominence ( 16.07.2022)Refractor H-Alpha 230mm
Hello
Our star showed us a great activity this week with beautiful filaments that have "snaked" on the surface for several days
one of them to benefit from the sun’s rotation presented us with a beautiful arch
I also present to you other HR plans of the chromosphere of last week
Seeing very average because of the heat wave , not simple at this moment to image the Sun

JP,
Do you have a picture of the 230mm refractor you used for these images? It's among the largest here.

Here is a link that shows not only the telescope but also its construction: http://jp-brahic.chez-alice.fr/lunette_230mm.htm. He basically built it from the ground up! This page shows the original setup with a PST etalon.

These are stupendous. What a scope but also what skill to coax these images from that b/c I'll bet a scope like that leaves no room to hide! I particularly like the 4th one. Bravo.

Re: Huge Solar Prominence ( 16.07.2022)Refractor H-Alpha 230mm
Hello
thank you very much for your comments
here is an image of the Solar Telescope H-Alpha , I started its construction in 2012 , since there have been some evolutions, notably the passage of an Astro-Physics 1200 GTO to an AP1600 GTO more comfortable to support the 40 kgs of the optical tube and especially from a PST MOD to a more efficient 0.3A° Solar Spectrum filter , the whole weighs 155 kgs ( 341 lbs )
a video that shows the old set-up in 2013 sorry it’s in French
https://www.youtube.com/watch?v=oL9aA2U6ra4
the construction is described in the book Solar Astronomy : https://solar-astronomy-book.com/

What a beautiful instrument! You have the third 228mm refractor on SolarChat.
Now will someone here buy a 230mm or 300mm Lunt!! Or a 10" 250mm plus refractor! :-)

"What a beautiful instrument! You have the third 228mm refractor on SolarChat.

thanks
I had the very first H-Alpha 228 mm from Istar, I asked Ales at the time if he could do the optical design for a refractor specialized in the H-Alpha above 200 mm
I have also in recent years a Clearceram Cassegrain Telescope CFF 350 mm F/D 20 with an Aries Triband 312 mm filter, but it is difficult to exploit, for 300mm and more it takes a seeing well below 1" , 0.5" ideally, there are few places in the world where you can reach this level of diurnal seeing, I have a very good home site or sometimes the SSM indicates 0.3", but it never lasts very long!!!
according to my statistics on my observation site, I can use in good conditions my Astro-Physics 155mm 90% of the time, the 230 mm 30%, the CFF 350?? I don’t know, maybe 2% or 3% of the time

Re: Huge Solar Prominence ( 16.07.2022)Refractor H-Alpha 230mm
That’s a beautiful cassegrain. 350mm is huge for an amateur solar telescope. I know my seeing here would very very rarely ever let me use it in the daytime. But if it did it would be phenomenal. I certainly wish you luck with excellent seeing!!
The AP 155 is a dream scope too. I am surprised you don’t have a Takahashi.
