I found that you are quite right I will try to check the goals before shooting.

John, I'm sorry .... I think in all the photos that you did not in the sun there is a fire first.
Therefore it is almost impossible to see sunspots so defined.
According .... sunspots are generally less numerous, somewhat more irregular and surrounded by a zone of intermediate brightness. Besides that I suspicious ones very close to the edges of the solar disk which, however, appear to be "flat" and not in "perspective" as they should be due to the sphericity of the sun.
Last .... with a filter and a telescope astrosolar Ziel you managed to photograph the solar flare? And then so many?

This above is the true appearance of the spotssolar .... and also this is slightly blurred

Do not take it but I think you have to try it again ... then if you tell me that you did a processing with Photoshop (regarding flare) I can also say that it is processing a pleasant ...

Gianni, your gear is fine, at least for very big shots without pretensions.
Covering better pictures I came to doubt you've clicked approaching the camera to the telescope.
If you tell me exactly how you've set up the equipment I can try to give you some advice.
The photography Solar did blaspheme me too in the past. :-D

3Cbr /> The second sifting the focal applicator with a photo (I use this technique)
In light of what I've written, those that you believe are sunspots, actually may be some dust particles on Barlow.
Let me know how it goes ...

This is the sun taken with a Ziel 80/400 with direct fire a Canon d60 (SLR 2002 by 6,3mpx) filter astrosolar, flares or flares are seen only with the filter h Alfa-if I remember correctly.

Unfortunately I have a little good a Barlow lens that gives me problems.

But how many mm focal length you were?

Exactly .... flares are visible only with optical filters or H-Alpha or, with a record eclipsing (technical rather difficult) In fact, the flares are being photographed in natural light, even during total eclipses of the sun. The fact is that the flares are too bright and are hidden by the strong light of the sun.

Sorry if I have not answered in time. Fabio, Richard, flares are a processing CS 5.
For when it concerns the question of the focal Riccardo was 5.6.

Gianni .... maybe 5.6 is the relative aperture of the telescope, that is the ratio of focal length and diameter of the lens free.
Incidentally if you used a 2x Barlow opening passes relative to 11.2 becoming less bright. In practice, it is the equivalent aperture objectives.
Maybe 560mm?
