April 9 started off rainy and partly cloudy at best. I had taken the day off, but given the forecast I wasn't really planning on doing any astronomy. However, later in the day the Sun started peeking through the clouds and I decided it was worth giving some solar imaging a shot. So I brought out our LS60THA with 50mm DS and gave it a go. I dodged through quite a bit of sucker holes before the sky cleared temporarily long enough for a set of captures.

 

I captured a full disk image with a ZWO ASI174MM. As I processed the data, I felt like doing a little experimentation and tried a few different flavors of color/grayscale palettes.

 

Let's start off with plain-vanilla grayscale:

Now, here's "plain natural (arbitrarily set)" colors:

Here is a greyscale version with the disk inverted:

More flavors:

 

"Plain natural (arbitrarily set)" colors, with the luminance of the disk inverted:

While I was at it, I thought I'd see how inverted disk colors (and luminance) would look:

As interesting as the prominences were, I decided to give them some close-ups, so I swapped out to a ZWO ASI290MM and an Astro-Tech Barlow.

 

Enjoy,

Eric

These are all very nice capture and process Eric! You captured a lot of nice details. I like the various color palettes you got. Nice to have fun with the images. It’s all about the art that makes photographing fun and interesting

Love the very first plain-vanilla B&W shot!  Closeups are nice too.
