DSLR solar image getting ready for eclipse

[gregbradley]

I thought I'd test a setup for imaging the sun with a DSLR.

I have several lenses I tested on the weekend to process as well to see what makes a good widefield setup.

What solar film/filter are you using?
Just curious as I don't get any where near as much "spill" from the sun as you're getting...?

[gregbradley]

That spill is somewhat controllable with even shorter exposures. Its a personal preference to have some as to me it adds to the image as long as its not too dominant.

Baader filter.

would it be safe to put solar glasses infront of a DSLR and image the sun?

[gregbradley]

Better to tape it so it fully covers it. Its worth a try.

Mark, the lenses in solar/eclipse glasses are small pieces of Baader type film so you could make two filters from a pair. One of the threads has an example of a filter made that way. Be sure you seal around the filter to stop any leakage and that it can't fall off the lens.

I'd expect it might cause some serious vignetting.

I've done that here: http://www.iceinspace.com.au/forum/showthread.php?t=99072
And also discussed a bit in this thread: http://www.iceinspace.com.au/forum/showthread.php?t=99073

Also regarding vignetting, I'm sure you would get some if you had a 1200mm lens but with my setup, a 7D + 200mm = 320mm, the sun is quite small so I'm never using the entire area of the filter.

Good luck with the eclipse!
