Decided to give the moon another go I think I have made some progress since the last ones. Don't hold back I can take all that you can throw at me I have a tough hide
I think I did see your last shots Warren, but could you give a bit of info on how these were taken (camera details etc).
Looks like some nasty vignetting on the first couple, but that last one is a beauty!
You could always crop down a bit if you're after a higher magnification shot.
They're great shots.
re. the last image
I think you may have over sharpened, it looks like there's a bit of snow on the mountain tops.
Otherwise you've done very well indeed. The contrast is excellent.

Ok as a real NOOB I have to ask for an explanation of vignetting does it mean when the edges seem to stretch out. The Camera is a FUJIFILM FinePix A500 the settings were f/3.3, Exposure time1/480sec, ISO-400, Exposure bias 0 step, Focal length 6 mm, No flash. Just held up to my 10" DOB on the last one with 20mm the other 2 with a 9mm is this what you were looking for. Thanks for your help to learn where I am going wrong or right

Thanks JJJ I did wonder if I had over done the sharpening I appreciate the help to learn where I am going wrong
You're welcome.
I started off imaging with my 10" dob too, afocal, with a variety of cameras. So I know how hard it can be, and how much satisfaction you can get from it too.
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

No, you don't see much detail in the .avi. It's all in the processing.
I used to use my 12.5mm or 20mm ep, and a barlow lense. Use optical zoom only, not digital. Get the planet in the field of view, focus using the telescope, not the camera. Set the camera for say 25 frames per second. Shoot for approx 10 - 20 secs. Open the .avi in Registax, deselect the bad frames, you only want to stack the best of the best. Let Registax do it's thing, and in a few minutes you should have a not too shabby image of Jupiter. It takes time and plenty of patience to get the hang of this method, but it's worth it. You'll be learning skills that will be invaluable down the track.
just go through frame by frame, using the arrow keys on your keyboard, hitting the space bar will deselect frames.
toss any that are smeared or really fuzzy.
sort through the images a few times,
it takes time doing this, but you will be rewarded for it in the end.
You're looking for images that have crisp edges, ones that actually show the banding of the planet. You may end up throwing away half of the frames, or more. You can still get a half decent image stacking only 50 frames.
Thanks I have heard people talk about histograms and other things that made my mind boogle but that sounds simple at least until I learn a bit more. Do you go to the fireworks in Brisbane. Hope you enjoy your NYE
atm you just want to get yourself a good basic image.
worry about the more intricate details of processing down the track.
Have a great new years Warren.

Good call, I agree, small steps, each time improvements are made, and don't worry if one day the image fails it happens. Errors allow us to gain experience.
