    Wow!!! For weeks we have been under relentless heat that feels like 110+, Saharan dust so bad it blankets the sky like I have never seen before, plus humidity so thick you can cut it with a knife. So, I said to myself "Screw it! I'm trying for a solar image. I'm tired of not being able to image or observe." SpaceWeather was showing a very active solar disk and I wasn't about to pass it up.

    Out of a total of 60 images I had one that looked promising. It's a single image, no stacking or sharpening. I simply adjusted the size and the brightness/contrast, plus added a little blue hue to make it easier on the eyes. BTW, I took that image with the camera on AUTO mode. The ones I took in manual mode were horrendous.

    nice given your conditions
    By the way what do you think about using a Hershel Wedge rather than solar film?

    Thank you.

    The main reason I don't use a wedge is because they are much more expensive. I also believe the scope can heat up internally because the light is not blocked from entering the tube. The sun can be really ferocious in the tropics.

    I have read that a wedge has the advantage of giving sharper and more detailed visual images. I only do AP and can process the data to bring out detail and sharpness. With my TV-85 I can get fantastic images on a good day.

    Great image, Ed, especially considering the conditions! I was fortunate to catch a decent pre-dawn sky to image Saturn and Jupiter before work. I'm looking forward to opposition; hopefully the sky will have settled down a bit by then, lol.

    Regards,
    Reggie :)
