White light imaging.



Clear sky this morning, though clouds quickly moved in about 10.00 a.m.

Managed to capture a couple of solar images with the 90mm Maksutov, mounted on the sturdy eq3 mount. 

Makes a big stability difference when the telescope weighs less than the mount!

The images were taken with our old Nikon D70. An old camera by modern standards, but it still does the job fairly well. 

When I consider my first "astronomy" digital camera was a 1.3mp fixed lens two AA battery compact, then the D70 will more than keep me happy - for now.

Visually the Active Region 2882 stood out really well through the tiny Maksutov.

With a 25mm eyepiece the sunspot grouping could easily be seen and was bigger than expected.

I haven't taken any white light images for ages, mostly I've been lost in Ha light these past few months.

Sol imaging: 22nd August 2021

 

  

 16h 15m UT -40mm PST/Samsung S6

 

I've not seen old Sol for going on nearly a week!  Lots of slow moving clouds had put pay to any observations.

This afternoon the blue skies prevailed and I was able to capture a few images.

 

I wanted to give an impression of the full solar disc and also capture the several small prominences that were visible.  

After a bit of fiddling with an image I settled on the picture you see here. 

 


 

Not the best image; that is obvious, but it does clearly show several of the prominences and their positions.

 

The white dots seen on the surface are some processing artefacts I couldn't delete.   

The program used to process the images is GIMP 2.8


Imaging and photo processing does not come easy to me, I would prefer pencil and paper, but today I thought I would try my hand at a bit of digital photo editing.  

Here's the final Ha Sol image capture:

First clear Sol image for a week.

Wow... it's been a week since I was last able to image the Sun! 

The weather these past seven days has mostly been rainy and cloudy. 

Or alternatively cloudy and rainy, depending on how you look at it!  

This afternoon the Sun came out, and all was forgiven in an instant.

I took my time observing those two beautiful prominences. 

They were so delicate, wonderfully tenuous, definitely ethereal.

When the West wind blows.

There's some windy stormy weather heading towards Pembrokeshire over the next few days. Looks as if I might not have a clear night for a...
