This is great Valery, however how do you stack your images? I have taken some lovely videos through the C11 and my eye can see all the detail but once I stack in ASK3 the image is a complete blur and nothing can be salvaged from the stack. I gave up and posted single frames at one point as they were...

These are absolutely delightful, especially pic 2 beautiful!!

I do like the tower prom, it looks most impressive on the full disc to see the scale of the thing
It's beautiful and sunny today, pity I am at work.

Alexandra

"but a correct postprocessing will completely remove the SA impact on the image"

I would dearly love to know how you do this

Alexandra

It is always a joy to watch animations of prominences. No matter how hard I look I can never see the plasma moving up, always down, so where does the plasma come from if it is always down


Alexandra

Wow! very impressive Lou

Alexandra

Wow!! I have never seen seeing like your first image well done.

The contrast is much better on the 23cm one though, even if the seeing was bad.

Alexandra

Terrific Marty, you are so lucky to be able to image when there are these magnificent proms on show I love the animation best

Alexandra

Wow! these are fantastic well done picture number 1 is very nice indeed

Brian, I thoroughly enjoyed your post, but very worried about your eye. I remember last time you had a year of blindness didn't you? we don't want you to go through that again! stay safe and rest lots :) All the full discs are beautiful :bow at least there were plenty of fine proms to really liven u...

Oh that sounds good, we could all meet up for a good solarchat!

Anyone else?

Alexandra

I was just wondering if anyone was going?

Not sure whether to go or not yet. Always nice to meet people if they are going as it makes the day more interesting. So I am undecided at the moment.

Alexandra

Does anyone have a graph of the Strehl ratio for a Celestron C11 at 393nm for full aperture and stopped down in 1 inch steps? Just interested to know when it hits 0.9

Kind regards
Alexandra

This is a super set well done :bow :bow :hamster: There are lots of tutorials in the Solar reference library, my particular favourites are from Mark T's website links in the ref library. However I think most are using Photoshop but when I have used GIMP I have found most methods can usually be found...

That's a beauty Franco, well worth finding that gap in the clouds

Alexandra

Well done Alfred, I expect great things from you

Alexandra

Wow!!! looks like I missed a fabulous prom this weekend
I wish the rainy season would end in the UK too, but perhaps that isn't physically possible

Alexandra

Beautiful delicate work, like a feather

Alexandra

That sure is a good project, fantastic results too, well done to you both a very enjoyable read.

Alexandra

These are fab Stuart, you are certainly getting nice spotty CaK images so the module looks good it is a breath of fresh air to see dots rather than dashes in CaK



Alexandra

Wow!! another beauty!! you have taken some real crackers this last week and a well deserved SPOD too

Alexandra

These are great, some super proms here

I would say that neg2 is far more on band than zero (which doesn't look very nice - sorry). I would try negative 3, 4 and 5 next.

Alexandra

Wow!! what a prominence!! super images

I can't see the images in the other post though
