Hi Josh, excellent images for a start and you did great producing a huge collection in just one night. Same goes with my Mrs

looking at your images, it seems focusing is abit off. As Paul have said, using a hartman mask will help with your focusing aid. If not, you can try focusing on a bright star instead which i do. Taking images are only worth 40% of a final image, the other 60% is the processing part. It is quite easy to take pics just point and snap but you will need to master the processing. What scope are you using btw? as paul have already said, the star bloat is because of maybe too long exposure (in your case it doesnt apply 30sec) or the white point too low in envisage. My advise is try a 60 second shot in preview mode, untick auto contrast and when the preview image is displayed on your screen, adjust the white/black balance manually instead. Always use preview mode before clicking the 'start' button. Try stacking around 25-30 images and see how it turns out since you are only taking short exposure shots.
I don't use a wedge at all. just using an EQ6 mount.
Programs that i use are:
- Registax (for stacking)
- Photoshop CS2 (processing)
Feel free to ask any questions Josh and thanks for your comments both Paul and Josh. Much appreciated you guys thanks.
Eric.
