Good Friday Sol...

[Peter Ward]

With arrival of some new gear I've been experimenting with High-res solar limb imaging techniques. The results seem promising.

Hoping for better results on days with good seeing.

Spectacular! Very nice, Peter

Looks like the conditions were pretty crap Peter.
Was that with a small chip Grasshopper or a Barlow?
When seeing suits you will see a big difference.

Thanks, but just OK me'thinks...I suspect, as Julia likes to say, I'm "moving forward"

Seeing was 2-3 out of 10. I use a PGR 6.0mp camera. This is a 1920 x 1080 crop.

It's not a big prom...FL was close to 4000mm....but I was happy enough to have caught some interesting structure in it.

thats a nice shot Peter. did you getthe other big prom opposite?

[Derek Klepp]

I will be interested in your opinion on which camera you find best for proms.Look foward to the results.

Ta,. 4000+ mm me is new territory for solar imaging focal length. Didn't get to it, as one of the reasons the seeing was ordinary, was the rapidly forming cumulus.....

Peter I was flying at the time I replied on I Pad and since then I have had a closer look with the computer. There is considerably more detail than I first though. That combo will surprise you, I think, when the seeing comes good.

Hi Peter
I'm doing a bit of a catch up and spotted this post. That is a good hires but defeated by the seeing for sure. I reckon that on average at those focal lengths you can throw away 9 out of 10 grabs. So 1 grab might be useable and then I reckon you would have to see about 10 lots of those before you get an exceptional image. I think your bang for your buck will go up considerably around 3000mm.

Of course you could be the lucky and have endless run of days with sub arc second seeing!

I have toyed with this type of imaging myself before Peter. Seeing has to be pretty darn nice. Not often I can use the 5x powermate to get the images up to 2500mm let alone 4000mm. Tough gig, but worth a look. I can see where you are headed and I still think this image looks good.
