The seeing was pretty good tonight with average transparency. I wasn't expecting it as the weather has been dodgy. So, I set up the Questar 3.5, tri-stand, and ZWO 178MM camera to give Jupiter and Saturn a go. 

 

I took a bunch of captures and these two came out the best so far. I still have others to process, so maybe there's something better.

 

As always, thanks for the encouragement to keep getting out there!

Terry,

Great pictures thanks for sharing. 

 

I'm always amazed at the images the Q 3.5 produce in skilled hands.

Great captures!  I tried, but was clouded outbawling.gif  I, also have a ZWO 178MM- I'll have to give it a try with my "Q". Would be interesting to compare images.  Thanks for sharingwaytogo.gif .

Terry,

 

Thank you for sharing your detailed images.  I was out observing last night at the same time. It's nice to know I can look back on your images to remind me of that special night.

 

V/R,

 

Matt

Thanks again everybody! Too kind. I wanted to catch the transit last night, but the seeing wasn't that good and there were plenty of clouds drifting by. I was able to catch a quick glimpse of Io on the edge just before more clouds obscured the view. It was super muggy so decided to call it a night.

In another post you mentioned you used a green filter to bring out the contrast?

David, that's correct. I have a full set of ZWO LRGB imaging filters (with filter wheel) for imaging, but a lot of times sticking to just the green filter provides the most stable, sharp, and contrasty captures. There are many times when I can only get good focus with the green filter. Usually green and red work best for me, with green having the definite edge. If I ever get a handle on WinJupos I'll start using all of the filters because that program will allow me to take 3 minute captures per filter, then de-rotate them for a final image. Plus the mono camera has better sensitivity versus the color version. Either that or buy a ZWO 178MC (color) camera and see how that works out. I like the big chip and small micron size in both versions. Works great with the Q!

I find that both green and blue filters (not stacked) do a wonderful job bringing out contrast and making the narrower temperate cloud belts and the GRS really stand out! With the smaller aperture of the 3.5” Q, I prefer the medium and lighter shades. The Wratten #47 is too dark; the lighter blue #38A is preferable. For green, I prefer the lighter #56 to the #58.

Be interesting to use a filtered monochrome for the luminance and the color only to provide and color value.
