White Light Shots from Yesterday Morning with a ..... 3 inch.

Post by Cschur » Wed Dec 28, 2011 8:24 pm

Hi all,

Here Im still pushing my 80mm f/6 to the limits to see what I can record on days of moderately good seeing. Yesterday morning was fairly good and I obtained some pretty hi res white light images. Now granulation is specified in most books at 1.5 - 2 arc seconds in size. Dawes limit for my 80mm is 1.4 arc sec, so by recording granulation clearly is really pushing the limit. Here is a shot with the 5x powermate, Continuum + IR, Wedge and 3 GB worth of data from the DMK51:

(click on this to see the big one for stars sake!)




Now here is a limb shot, same setup but a mere 500 frames:



On the opposite Limb, this one with good faculae:



A full disk shot, but this one was with Astro solar film, Contiuum + IR since I cant get to reach focus with my wedge at prime focus by about an inch.



Finally, I took this one while waiting for the sun to rise above the nearby pine trees. I live at a mile high elevation, and every tree is a pine tree!



Thanks for looking, Please feel to comment on what I am doing with the 3 inch...

Hi Chris:

Great HR WL images. You are really pushing your Zeiss 80mm to the limits. I usually image with a X2 apo barlow but the focal length of my FS128 is longer. It is difficult to do much better with the sun so low in the sky. Congrats.

You mentioned in a different post that you used AVISTACK. I prefer Registax. It is must faster (version 6) and it does a good jod. You have however to play a little with lots of options. I guess I now understood most of its aligning option. It you don't do it right you end up with a deficient alignment with lots of lines in the final image. Do you have the same experience?

best

Pedro, I had to use AVIstack because Registax 6 will not open files from my DMK51 larger than .999 GB. BUT there is another reason I use it - just for stacking, it batch processe the massive amounts of data in about 2 hours, and the images are ready to post process in Registax wavelets which is far, far better! I will let you know how this works out. As you can see by the first image here, it found all the clear spots in the granulation. when I processed the 1gb shot - which was only 500 frames, in Registax - half the image was blurred. Each is good at something different.

Hi Chris:

I guess you need a new computer with more RAM to process your images. I use a Toshiba laptop i5 4Gb RAM. It works fine.

best regards

The first is absolutely gorgeous but I must say the last shot took the favourite position!

Thanks Everyone! I think granulation is what defines a good white light shot. The more the better. Im surprised a bit on how well it shows up even on a full disk shot with the green filters. That was un expected. Ill try to get a shot of the observatory today with all the snow around it....

Hi Chris. Please send the observatory shot with snow. It will be interesting to star a topic describing the setups we use to observe and image the Sun. I guess Bill already sugested that. Shall we do it?

best regards
PS- We still have clear skies in Portugal (15 days straight and going...). High clouds but no rain will arrive in two days ;)

Yeah, its all cactuses and sandunes. But NOT at 6000 feet at my observatory in happy jack. (See latest sky and telescope on the Discovery Channel telescope near my house)

Here is the snow shot I took today. It was below freezing at sunrise, and what in the world was I doing outside solar imaging? ;)

Oh my...

You live in the most wonderful place, I am so envious. I guess you can't see much looking that way, what is the view like 180 degrees round? you are so lucky. Do you just drop off a cliff that way? could be dangerous in the dark if you exited that side :)

Im on a big flat plateau just before the rim steep cliffs start. Its in a small subdivision, with about a hundred houses or so. the view the other way is solid pine trees.

Hi Chris

thank you for that shot. Fantastic view. Yes, me too I miss some movement in your mouth angles ;-)
