In these weeks Venus is visible in Holland but probably also in whole western-Europe. It's a very bright ''star'' in the south-western eveningsky (against 8 or 9 o'clock) Maybe someone can point a telescope to that?
Actually, its not so much as it is too bright. Its just that it maybe too small or too far away for your scope's aperture to resolve properly.
I've looked at it with my telescope (4 or 5 inch I think) and I'm going to agree with those who say it's 'too bright'. It's brightness causes some 'artifacts' when looking at it. But I also don't think you'd ever be able to see much else. I think it's dense atmosphere should prevent you from seeing much and would reflect a lot of sunlight.Actually, its not so much as it is too bright.

I have looked at Venus with my 6'' reflector ( last year I think ) and saw this half shaded disc, kinda like the moon looks when its waning.

Venus won't show any 'features' but you will see that it's 'fuzzy' because of the thick atmosphere. Though it's hard to distinguish this fuzzyness from being slightly out of focus.I wouldn't even think of seeing much. From Earth, it should look totally featureless.
Is that really why I can't seem to get my image any sharper than this? I thought it was just due to stacking images from my SLR instead of a webcam. It's only 4 of the best images stacked (I tried it with more of the frames I took, but it seemed to do better when I was picky) - it was a very quick and dirty job night before last.Venus won't show any 'features' but you will see that it's 'fuzzy' because of the thick atmosphere.

Possibly. It could be the focus, or it could be the atmosphere.Is that really why I can't seem to get my image any sharper than this?

Thanks! I used an 8" LX200 Schmidt-Cassegrain. I might give it another go with a webcam based imager later and see if I get the same result. The quick and dirty way I did this shot was just begging for problems.It's a cracking shot of Venus regardless! Good work. What scope did you use?
How did it look through the eyepiece? If it looked similar through the eyepiece and the stars were pin-sharp then it's probably the atmosphere and you can't get it any more focussed. Nice scope by the way. I wanted one of those, but couldn't afford it so had to go with a second hand 8" Celestron (Ultima 2000).Thanks! I used an 8" LX200 Schmidt-Cassegrain.
