Solar Composite (most of it!)

Submitted by thenakedastronomer

As you can see in the photo below, the sun is BORING right now ... absolutely nothing going on.

So I decided to spend a few hours and do a composite of the entire disk. This is a combination of 30 images ... processed with Autostakkert and Registax ... but ... wait ... I missed a piece of it!

Well, I guess this just means I have to try again. Darn. Twist my arm, why don't you... ;)

Anyway, enjoy. This is what keeps you warm. Keeps you alive.

Always fighting this .... odd how the rings are more prominent in some photos than in others. I was reading tonight of a processing technique that may minimize them, so I may do some work on this tomorrow ...

The way I was told to fix this is to de-focus on the center of the sun, bright area, and take flats. I found a way to eliminate the rings all together at the source. I bought a DayStar Interference Eliminator w/C mount. Pricy at $175 but it fixes the problem at the source, camera not being lined up perfectly, something in the optical path is a bit off. One less step in processing, and well worth the price if you ask me.. I think you should come pick mine up and give it a try before you make the purchase. Shoot me an email when you want to give it a try. I can bring it over if you like, but I need a shower so give me a heads up :) Your on the right track Jim, keep it up!!

That's pretty cool Jim! I think you'll have that mastered pretty quick being you have the processing part down from your night time photo's. I have never tried to do it, don't think I ever will either, lol. It is a good thing to learn so you can blow up the size of the sun. I always used a 0.5 focal reducer but it makes the sun small, then I dropped it, and it broke :(
