27-7-12 - Sun in HA

[DrRobin]

Hi,

Managed to snap this shot of the sun in HA with a PST, DMK21 and a barlow lens given to me by Ant. I seemed to loose some of the surface detail when I merged the two pictures, but generally pleased.

Each exposure was around 1,000 frames and I took the best 350 or so for stacking.

I also need to find a way to get more surface detail, possibly need more frames to start with and use a higher quality?

One quick question, I didn't use an IR filter and I am guessing this is correct as the Etalon should be narrow band?

It's sunny again today, stuck at work at the mo, but hopeful of another go later.

Nice shot. As you said, no need for IR filter.

Thanks Freddie. And thanks for the confirmation on the IR filter.

My sun has gone now, in fact it is raining and I am still stuck at work. Too much work, not enough time for star/sun gazing.

Try a session just focusing on the surface (if you excuse the pun!)

I find the tuning needs to be tweeked between the proms and the surface detail. (some others are lucky/ happy to just push the gain...)

Work with Registax 5.1, pick the best 10% and gently apply some level 6, 5, 4 wavelets in decreasing amounts....

Practise, practise, practi.....

Hi Merlin,

All good pointers, thanks, it is just practice. I did take some more pics today and posted one on another thread on here, which is an improvement. Since posting that picture I have reprocessed using 'Drizzle' and selected a different frame/alignment size, the result is much more detailed and sharp.

I didn't finish it before going out for the evening, so will have to post tomorrow.
