Sunday Sunshine in Reasonable Seeing - 24th February
Sunday dawned clear for me, much of the country seemed to be shrouded in fog, but for some bizarre reason I seemed to be missing it and was treated to blue skies. It became apparent very quickly that the seeing was oscillating from something semi decent to appalling, so I quickly got the SSM up and running to catch only the best offerings.
Starting off with the full disk in Ha with the SM90 I was pleased that the spicule ring had 'texture' rather than the flat featureless one that I had yesterday. It wasn't quite 'hairy' so I would say my seeing was 'middling' - maybe a 6 or 7 out of 10.

Things were quiet in Ha with few proms and little on the disk. I was playing double stacking with the Quark when an Icelandair flight presented a nice transit for me...

I was running a sequence of frames for a time lapse, but nit much was happening very quick, here is an 8 minute view. I still have stills to process of this area.

Frustrated with yesterdays attempts at CaK I was keen to try a different approach, first off the full disk at 60mm f15; the seeing was behaving and this has lots of potential when there is more to see. Be sure to click on the images in flickr, they're large.

A fine set of images, Mark. You had a bountiful weekend, including a fine jet transit

Beautiful Mark! And one of the best transits I have ever seen.
What kind of CaK filter train are you using at the moment?

Thanks everyone for the comments!
Colouring the animations is easy Pedro. I select the frames I want from the avi file use the 'limit frames' and then 'export' in AS3. I then open the first frame in photoshop and process but record this as a macro. I then run the macro on the other frames. The processed frames are then made into a GIF file after aligning etc.

Re: Sunday Sunshine in Reasonable Seeing - 24th February
These are fantastic, especially the CaK full disc (I have a long way to go in CaK )
I love the transit and the animation, loads of action going on even in 8 mins of a quiet Sun

Re: Sunday Sunshine in Reasonable Seeing - 24th February
Went through the calcium closeup avis and found the sharpest overall from the 15 or so I took, then found I got the sharpest final image from a stack of 12 sub frames. Here it is presented. Makes the previous version seem quite soft and mushy in comparison.

Wow Mark, beautiful additions! And they inspire to go through my own CaK Avi's again and use even les images to stack.
What is the CaK filter combination you are using? CS! Bart.

Thanks Eric. Hi Bart, the CaK PST filter module goes as follows: Objective - Baader K Line, KG3, PST#1, Skybender, PST#1 - CCD. In this case I also had a Baader Blue filter ahead of the CaK module to keep the loading down on it.

In earlier images you posted you could see the CaK double limb. Did you choose to process this image differently? So more detail near the edge, but no double limb?

Re: Sunday Sunshine in Reasonable Seeing - 24th February
Yeah, I dropped the gamma a bit on this (0.8) in post processing, that always kills the double limb. I'll post up a gamma neutral later. TBH there was nothing happening in the spicule layer which is one of the reasons I dropped the gamma...

Re: Sunday Sunshine in Reasonable Seeing - 24th February
Thanks again Mark. The difference is obvious, so more inspiration to try different ways of processing.
