Also, your piccies seem to be a bit out of focus. Use your live view on your camera's screen to get the piccie in focus. I think your out of focus pics maybe due to you using a barlow...the seeing conditions are probably not good enough to get a high powered shot. Just use your EP's and try eyepiece projection instead. Try a 25mm EP instead of the 32, and for higher power, if you have one, try a 15mm. But still make sure you have good focus.

I am using eyepiece projection. I know a 25mm would be the optimum eyepiece match for my scope. I used the 32mm so I could encompass all of the moon available at the time (I also have limited eyepiece selection). Too many achromatic lenses in the light path, no live view or fancy doodads I'm afraid. Just an el cheapo sanyo fixed lens digital camera ,with manual shutter, and real low res preview LCD.
The focus issue has worried me and I've tried everything to resolve it to no avail. I think the focus problem is attributed to more than one factor, vibration from wind etc...manual shutter activation doesn't help either. This is why I've taken 1000's of images in order to pic the best ones for stacking. I think it could also be my eyes. Sometimes I spend so many hours looking it strains my eyes, that and the fact that I look at computer screens all day....
If you notice there is also some chromatic Aberration (the blue tinge). Even though the Mak has good colour correction, and I used an APO barlow, the 32mm camera projection lens is still Achromatic. I'm currently looking for authentic Apo eyepieces or fringe killer filter to resolve this. Otherwise I could just use a yellow filter.
Although a yellow filter would be effective in eliminating chromatic aberration it would also mask the natural beautiful colours of the moon. If you import the image into photoshop etc... try and turn up the saturation, the images look interesting to say the least. I think I might do that and re-upload for all of you later.
Thanks for the comments.
