Finally after days of cloudy skies, the clouds parted this morning to let me get a shot of the large Sun Spot #1476.

That is a beauty, Ron.  Great shots.
It lilkely is partly responsible for one of the "largest ever recorded" solar eruptions this week; very active sun and they are expecting more.

Nice image of the sunspot. I was looking at them regularly but it has been a while since I looked. I was hoping to check it out today but it is cloudy in AR. I would be interested to know what you are using to do your imaging. I am going to try using a webcam during the transit of Venus if I am able to see it.

Are you using your LX200 with a full 8" solar filter or is the filter less than 8"? I am using a 70mm reflector with a primary filter but have not tried to image yet.
You are getting good results with whatever you are using. I really liked your 2004 Venus transit images that you posted recently.

James,

I'm using a full Baadar white light filter with my 8" scope. All images are single prime focus shots with my Canon Xti. The first image is a single shot with a 1.6 barlow slightly cropped. The second image is two halves put together with the PM function in my PSE.

If you are using a webcam you should come up with a lot more detail with stacking the images than I get with a single shot.

Thank you all for the compliments,

Ron

Ron, very nice.  Visual using white light Baader filter was very enjoyable thru my Explore Scientific 102.   Keep looking up.

Thanks mladams,

The white light filter has done me well so far, can't wait to see the Venus transit, and I hope the weather cooperates smiley

Some day, if I win the lottery, I would like to have one of the more expensive solar scopes, that's just a dream though grin

At this year's OBS, my Astronomy Club's winter star party, I was able to really enjoy watching some of the solar prominences from one of the member's setup.  It was the first time I have ever seen the Sun in action in real time.



His scope was connected to a couple of PC monitors located in the little tent.

I have a question....  have you done a comparison of the Baader film verus a glass filter?  I keep hearing conflicting comments about one being better than the other for contrast.  As well is there any benefit for a full aperature filter vs an off axis one?

I haven't done a side by side comparison so it's hard to say which one is better.  I would recommend the full aperture though.  I prefer looking at the full disk of the Sun, or as near to full disk as you can.  I always thought I wanted a Thousand Oaks glass filter because of the yellow image of the Sun, but after using the white light Baadar I'm perfectly satisfied with the images I get form my scope, and the price was right grin

Maybe some other members can drop in a give some more input on different types of solar filters.
