Sun in white light - Attempt 2

Having remembered that I had one of those trinket SW kit barlows with a removeable nosepiece, I went out to check whether it would allow me to achieve focus through the Lunt wedge. Cor blimey, but the sun came out and even though it was 6:50pm, I couldn't resist.

Lunt wedge, Solar Continuum, EOS 450D. 10 frames stacked in Registax after downloading it and without reading any tutorial! Cropped and adjusted to (poor) taste in Gimp:

Hi Russ ,

With a wedge and continuum filter I'd expect a lot more detail , I would lower the exposure considerably , a 'dark' image can be adjusted up afterwards but an over-exposed image is impossible to retrieve data from , once it's saturated it's beyond repair.

Thanks for the kind words chaps.

Like I say, I only put the camera on the wedge to check for sufficient in-focus. I really didn't have any intention of taking any pictures, especially as it was blowing a hooly. Not ideal with a 1200mm long frac on an EQ5 type mount, I'm sure you would agree! Heck, I only got ten exposures because I thought I'd set the self timer to 10secs, rather than to 10 exposures with a 2sec delay....

Anyhoo, now my Revelation Apo triplet Barlow is here, I'll start paying more attention to what I should actually be doing. Expect PLENTY of questions!

If anybody within a 15 mile radius of Cambridge fancies running a solar imaging master class, I'm all ears. :)
