A very busy sun

[Sam]

Here's the full disk, there's no bits missing this time. I think I've been a little heavy handed on the wavelets on the last few so this time I've minimalist.

And now for some close ups. There's a lot of dust on one of them which is a bit odd as it was the same set up for both, must be the way I processed them.

that's one very large flare!

[Sam]

It certainly is, it was very spectacular in the eyepiece as well.

Wow! that prominence was massive! these are beautifully processed and presented I think the bits on the close ups look more like stacking artifacts. I would try running them through another program and see if you get an improvement. I always try Autostakkert 2, then Avistack 2, then Registax 5 if all else fails, usually one of them gives a clean result.

The full disc is very impressive and that prom, huge, that is one great capture. I think you could probably boost the contrast a little bit and reduce the brightness to bring out the detail. I had a little play with your image, adjusting the brightness and contrast, shadow and highlight, saturation and hue and I have lifted the detail a little, I hope you don't mind?

I am guessing you went for one exposure to get the prom and surface detail in the same capture? If this is the case it looks like you had to over-expose on the surface to get the prom detail? A better method is take two captures one for the surface detail and then one for the proms, with higher exposures. Just cut or blank out the disc on the over-expossed proms capture and merge after stacking. I usually take around 2,000 frames for the surface detail and about 500 for the proms, that way it keeps the overall capture to a reasonable time limit. Anyway just a few suggestions, hope you don't mind?

It is nice that someone is seeing the sun in Ha, totally clouded out here for the last couple of days and I think NZ is a little too far for me to travel at the weekend.

A really nice capture there, loads of nice detail coming through too.

I agree with Robin with taking two separate images for proms and the disk as it's what I also do when imaging the sun, I'm sure with a little more tweeking and maybe merging 2 different processes of a proms and then disk of this original image you can get even more out of it. It's a great image already but I'm sure you'd like to pull as much out of it as possible. (Hope you don't mind my opinion/advice)

Congrats and keep them coming

[Sam]

Thanks heaps for the advice, I'll have a go today at the two different exposures. Looks like a nice sunny day again.

[DrRobin]

Oh lucky you. My forecast is for cloud tomorrow, but there might be gaps and we might see the sun. Good luck with your captures. I try to go for about 75% on the histogram for the surface and what looks right for the proms. Then stack and merge the two images afterwards.

I use Registax 5 mostly, although I have tried AS2! for the close ups. I seem to get mixed results with Registax 6, sometimes it works and other times gives me crazy paving/fractals.

[Sam]

There's a bit of high cloud hanging around at the moment but as soon as it clears I'll be out there. Thanks for the tips.

Very impressive Sam, that is one active sun.... Those images are cracking
