I see you're shooting at iso400. Unless you're going to be stacking multiple images to get rid of the noise, I'd stick to iso100....200 at the most.
You will have to drop your exposure time down to around 180th of a sec. But you'll be rewarded with smoother images.
I personally wouldn't use an eyepiece smaller that say..12.5mm.
The vignetting is horrendous, as you can see from your first 2 images. You want your target to fill the sensor of your camera. It makes for a more attractive image. If you want to get up close and personal, use your computer software to zoom in on the area, then enhance digitally.
Do you have a video function on your camera????
If you do, we'll have to talk planetary imaging next. Great fun!!!
Hi JJJ yes I do have video on my camera and I took a few 1 min video's of Jupiter but when I look at the video it looks very pixelated and no detail whatever I don't know if this is normal for the video or not
