This shot would be more representative of what a typical smaller beginner scope captures (unlike those fantastic pics posted by more experienced and devoted imagers on this forum)

Using an ETX-90 I could not get the zoom details but there's still beauty in the way the moons arrange themselves. Used the same HP HD 4110 webcam. Will try this on the 10" SCT once it's on a mount.

Thanks for posting this image m1618! I really enjoy what I call "small bore" imaging with my 4" and 5.5" refractors. Jupiter with the Galilean moons is a perfect subject for small scopes and you did a good job capturing the action. Wish we had more small scope users posting...

Tried something similar with my SW ED 80/600 last night:

ED 80/600, powermate 5x, basler ace mono +UV/IR cut, 2000-5000 AS!2, wavelets in registax 6

The next time, I will try being a bit more selective of my images to stack and adjusting the wavelets more. I might have tried too hard to capture more color but lost out with contrast and brightness. valy, you had some good details in there. Nice.

Usually it is easy to process separately, Jupiter and satellites, and overlap them at the end.

Just like with big aperture, seeing is the limiting factor far more than most people realize. Under good conditions a quality small aperture scope can really shine.

Thanks m1618, it's not often a thread gets started with small scope images and it's nice to see folks replying. I mentioned earlier that I really enjoy shooting with small to mid-size refractors, and wanted to share a few pix. In 2010 I did a lot of imaging with my 100mm/4" SW100ED f/9 OTA,and when the seeing was good it could perform very well indeed. This side-by-side shot is an example of what can be done, the detail that small scopes can resolve still amazes me...

Clear Skies,
Brian

I also liked this shot which captured two moons in the scene that I was able to pull out through processing. Shooting at f/45 I had the gain maxed out and the images looked pretty dim...but it all came out in processing. My hats off to small scope imaging, I hope we see a lot more of it here in the future!

Those are amazing! Yes agreed, seeing is THE limiting factor. I'm also surrounded by concrete/city lights/pollution/etc. A great international hobby though. I wish all the world could own at least a small scope to look up once in a while...

Amazing pictures, BKBrown. That's about the level of detail I managed so far to capture with my 180 mm Mak-Cass (on less-than-perfect but pretty good seeing).

Small scopes are not so bad, at least they handle well average seeing conditions.
This is one of the best Jupiter shots I made with my former scope, a 6" Meade (LS6) and an entry level color camera. The seeing was very good though.

Great images for a 4 inch!!! I've always loved the Jupiter pic at the bottom of this review taken with a Tak Sky 90 @ F/41!...

Some great images here. If you have good seeing, it's worth imaging Jupiter and Saturn with most any scope.

That is a terrific Jupiter image Tim! Small aperture can do really great things, the main problem beyond raw resolution is the loss of color. Images from large aperture collects have far better color saturation, so why not try black and white shots sometimes? They will help avoid the red tint often present in small bore shots and can be every bit as cool...

Clear Skies,
Brian

Actually flava is off topic with that image. Here must be small, soft, full of compression artifact, colorless images. Anyway 6" is not a small scope. :) :)

PS: flava if you enlarge this photo I think it can compete with all other good images around here.

Thank you Valy :)

That capture is probably my best with the 6" scope. It was a very improbable capture. That night the mount sofwtware went crazy and it was impossible to align the scope. I finally just turned it on, found Jupiter using manual controls, put the camera on and got lucky it was on the chip. Then I went ahead of it 5 times and let it zap through the chip while capturing, all in all I got about 1000 frames from all 5 films. The positive thing was the scope was still during the captures so there were no vibrations.

I have to post a crummy Jupiter too. I got it on 15th of august 2009 with a 4" Celestron achromat and a Nikon D40 at 200 ISO. Single shot with an exposure somewhere arround 500ms (hat trick to avoid mirror flip vibrations). I did what I could with photoshop (increase contrast and saturation) to get this:

Definitely Paul! Saturn is trickier than Jupiter in a small scope since it is so much dimmer. You will max out the gain, gamma at 100%...and it will still look very dark on the monitor. But collect enough frames and you might be pleasantly surprised during processing...

Brian

Brian,

Truly some fantastic images. My link at the bottom of my page has a saturn image i did through my dbk21au ttached to my C6. Seeing was averege-ish.

Here's my collection of images, using either a 4",4.5" or a 5" scope.
