Weather struggles continue here south of Dallas.  I have a break from the clouds yesterday morning and arose at 3:30 am to shoot some lunar followed by planetary imaging.  Pretty much a wast of time as the seeing was poor being sandwiched between two major storm systems (the one last night delivered baseball-sized hail to my sons apartment complex west of Dallas.

 

These were captured with my ASI678MC and the Orion xx16g.  I had pulled the optical train a couple of days earlier to set up the scope with the ASI585MC camera and imaged the Moon initially with that optical train still in place.  I swapped the 678 back in after imaging the Moon and used Enif to adjust the collimation as best as I could given the conditions (Think Daryl's comment about sparking stars (I'm not sure that was his exact phrase so consider this paraphrasing).  I am finding that the latest version of Firecapture that has added sharpening to the preprocess averaging feature has been helpful in focusing, especially on mornings like yesterday.  I usually need more time than I had with dawn approaching to dial in the scope after swapping cameras.  In any case here are the results for what they are.

 

Saturn stacked from a video derotation.  10% of 33,700 frames.  Processed in Wavesharp and Image Analyzer.  Final image size and canvas size applied in Paint Shop Pro.  This image is presented at capture size from a 1.5x drizzled stack.

Here is Mars taken just before I packed it in.  Fighting dew through all of these captures (Saturn and Mars).  No horrible dew but enough to need to check before each capture and hit the secondary with a blast from the hair dryer on every other one(ish).  Mare is just my reference frame.  The center 15,000 frames were stacked.  This is 11% of those 15,000 frames.  No video derotation was performed as the data wasn't worth the effort.  This image was resized 150% in paint shop and placed in the 400 x 300 px canvas used during capture.  Not because the data justifies the resize but simply to make the planet visible in the post.

I'd be happy with that Saturn! It was dancing too much to even make a real capture attempt at 5am local time here this morning. Getting so frustrated ...

 

Totally in agreement with the ability to sharpen-on-the-fly makes it easier to focus, at least on Saturn.  Can't wait to try it on Jupiter when it rolls around again.

 

Nice work (and at that time of the morning, it does feel like work!), Don.

Thanks Grant.  Appreciate it.  Yes indeed 3:30 am is a chore but holding off on DSO at the same time at least means I'm not up every 90 minutes all night long to check on captures.  I'm starting to think Daryl had it right.  Just sleep in until the imaging gods wake you up and say it's time to take the perfect image.  Funny how that seems to happen every time he and Pattie go out!!

I managed to pull Tethys and Dione from the background of the un-sharpened image.  They were then layered into the image of Saturn above.  Both brighter than they normally appear.
