Howdy!

 

My DSO setup has never been pointed at our closest star, and I really wanted to change that. I found the Spectrum glass filters on AgenaAstro and really liked the cost.

 

Yesterday I found myself with a few free hours and decided to get the filter and scope outside and pointed. Got 2000 frames in SharpCap, and actually captured and processed this entire image sitting outside on the patio. That was really sweet.

 

Go easy on me, this is my first ever attempt at Solar Imaging!

Thank you!!! 

 

Thank goodness for Wavelet Sharpening!

 

Id imagine with the full spectrum glass filter, it really wont get much different than this? Other than quantity and size of the sunspots?

Right. WL imaging is pretty much limited to sunspots and a hint of faculae near the rim. With something like the Antlia 393nm wedge you can get some more faculae from the photosphere but you hit the wall there:

I think many would conclude that the Baader solar film filter gives a better rendering of the disk than any glass (or polymer, in this case) filter, and it's true white, but that's about it. To see more you need to go to Ha or CaK filters.

 

Now you're talking commitment, but the payoff is fantastic! wink.gif

I'd assume it's the William Optics GT81 IV, from his equipment list, no?

That is correct! This was taken with the GT81IV + SFFX1 and going through my Green filter to the 2600MM running around 20fps. I did an ROI doing to 2000x2000 to capture the disk.
