Hi to all,
Once flew over the spotless sun eastern limb with a 280mm SCT (very poor at 393nm?) .
Bands were H-a DS, Ca-II-K 2.2A, 393nm 10nm
Seeing was average with some improvements to a good one.
Hope you like these photos taken during that flight.
PS. Flight #2 was near the center of the spotless sun and was successfull too. But this is another story. Will tell you later.
Right click on the images, open them in a separate window to see them at a full resolution.

Re: Flying over the sun eastern limb in a 280mm scope.
1. I certanly will do better, at least due to a greater aperture - the C14.TheSkyBurner wrote: ↑Sun Sep 23, 2018 11:18 pm The halpha is clearly much better defined than the 393.4. If you look at the top portion of your calcium image it is fairly blurred(this could simply ge from the low intensity transmission of the pst filter) Not complaing, its far greater than what ill be imaging and pretty much anyone else on the forum in the next 10 years.
But you can certainly do better!
Apples and oranges....
2. My goal is: all ARIES 2/3 bands filters owners should do at least comparable images, better if they will surpass my results.
3. This CaK image suffer from insufficient S/N due a rust on the blocking filter. Need to change the blocking filter.
Second reason is that at the edge the CaK "relief" is MUCH worser defined vs H-a DS. Regardless of filtration. This is nature of these supergranulation cells.
And, this is not my best CaK image. Far not the best.
Thanks for your critical note. Will work more about aestetical level of published CaK images.

These are thoroughly beautiful Valery, I prefer you to put all images up, not just the very best, it gives us something to aim for
Congratulations on a very well deserved SPOD

What filters are you using in the CaK module Valery?

Re: Flying over the sun eastern limb in a 280mm scope.
I do use Edmund 10nm 393nm, PST CaK #2 + PST CaK #1. I need to replace the PST CaK #2 with a second Edmund 10nm 393nm. Or just buy a Baader K-line filter and use it with #1 PST CaK.

Excellent images, Valery. You continue to set the bar very high. Thanks for showing us what CAN be done.
