I believe that, with the planets lying so low in the Southern skies, we disadvantaged Northerners need a league of our own, where we can show our best efforts to fight atmospheric turbulence and dispersion (not to mention roofs, trees, and other obstacles). With Mars being pretty much featureless and Jupiter far from opposition, let us focus on the beautiful ringed planet. 

 

I invite everyone to post their best Saturn of this opposition imaged from a latitude of >30 deg N. People should try to limit their post to a minimum (say 2 or 3) considering this is a "best of" and there is still some time left to do better this apparition. I'll start with my best at 26 deg. (which I won't beat for sure this year). Keep them coming!!

I sneak into this category at 33 degrees N latitude, although I feel you should probably have a separate topic for those of you who image at 40 degrees N and higher, as you all have even worse elevation, and less favorable position of the jet stream, which I am able to avoid much of the time during the summer months.  This is probably my best Saturn so far this year, although I've had several images of about this quality.

real nice image tom glen. it looks close to what i get with my 16. not bad for a 9incher. makes me wonder if I should just sell my 16 and get an edge 11

this image looks like its slightly out of focus or it would have even been nicer . do you use a motor focus?

From my home site Saturn never gets above the trees this year. I packed up the kit and took images from a clear cut up in the hills. The laptop battery ran down before I started on Mars. This one had Saturn only 21 degrees above the horizon.

Thanks for the complement Ferret, although your best Saturn images with the 16 inch definitely have more detail than my best images, as would be expected with the aperture difference.  I will say, however, that on most nights I don't feel like I am fully maximizing even the 9.25, given the low elevation of the planets.  I wouldn't sell your 16 unless you really run out of space.  The Edge scopes, 9.25, 11, and 14, are all excellent, and very compact.  If I had the money, I would get a C14 Edge, but the price jump from my current scope is crazy high, and there would only be a few nights where it would make a difference, at least on the planets right now.

My JMI motorfocus has been just delivered. So I hope to improve focus skills.

The same for a ADC.

From 39 degrees N latitude in the DC area...

 

Imaged on the night of June 29th when we had some of the best seeing in months.

Only had the scope on Saturn 2 nights (from 40N) this apparition.  Both times, Saturn has been incredibly poor - like poor enough I could barely see the Cassini Division Yet on the one night I was also able to get Mars (similar declination and slightly LOWER altitude), Mars was surprisingly crisp. Can't really account for that....

From 42° 28' N, Saturn @ 25°, back on May 31 at 071036UT. Best seeing I've had this year--- would have been really something if it was @ 50° altitude!

 

36.8cm Dall-Kirkham @ f/14.9 (5480mm EFL) with an ASI290MM using a focal reducer and ADC.

Both times, Saturn has been incredibly poor 

Hopefully we'll get some strong high pressure back soon, although the next few days look like crap

This was taken back in May.  The summer clouds have really been dogging us this year.

I went back and spiffed up my image from last Saturday, actually July 15 by the Universal Time Clock.

 

I used a bit of deconvolution and combined the best two shots with Winjupos. Location near 44 North.

Altitude 17° above horizon. Struggle with seeing is difficult even with an IR filter. I was just lucky to capture the polar storm. I like to find moons drowned in the noise. An exposure of 10msec was enough to detect Enceladus this time.

A couple of fine entries from low elevations...

Christophe, what do you mean by Altaz derotation? Is it a software correction of field rotation?

Wow, those low altitude ones are especially good.
Up here in sub-Arctic Ireland it’s the double-whammy of high latitude and low altitude. It’s hard to keep a good attitude as a result 😳

Cheer up Kevin, Saturn will achieve a whole degree of additional elevation next year and another degree the following year! Enjoy! grin.gif
