First Light - Saturn 2014rgb - & iR742+Polar map

Hi folks! - this morning we shot a couple of captures of Saturn in the morning sky..... but at the elevation, 0.6 mag & over 4 months till opposition it was probably a bit adventurous without very good seeing - which this most definitely wasn't!

But the "Hex" can be seen in these images if somewhat indistinctly.....with a ring tilt of 22 atm some nice seeing even now should give anyone (esp. in the Sthn Hemisphere) a good crack at getting it well defined.

In a similar vein the Sth Polar Zone is all but invisible as the rings almost completely blot that region out from view!

Still, it was good practise as we hadn't imaged for a month or more now...and this image is only 18 days short of a year to the day when another image we captured demonstrated that the NPZ hexagon could be imaged with amateur scopes: http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Board/Imaging/Numbe... ..."old hat" now but very exciting at the time as that thread showed!

Re that image from 2013 (not our best by a long way but perhaps our most "satisfying" ) Mike Foulkes (BAA Saturn Director) had me rush-process it just after Xmas for the 2014 European Astrofest poster...hopefully we'll get a memento if it proves useable!

Here's this morning's effort - a very rushed "in the field" processing job and I'm sure folks will see a few furphies that I've been too tired to pick up.....and it's off to sleep for both of us now (well, Pat's been snoozing for a few hours already! )

Perhaps tomorrow morning will have some better seeing..?!?

Edit: just added an iR742nM image plus a Polar projection map thereof...

Definitely excellent for first Saturn. Are you using basically the same settings as last year?

Great first Saturns Darryl! Got to love that ring tilt angle! Look forward to some more.

Thanks Paul (both Pauls) Frank, John, Rob, Steve, Mitchell, Sam, Andrew, JP & Vasco.....this is a very rudimentary image but I'm still glad we tried imaging "The Ringed One" this morning.

Paul, 75fps R&G with an 80%+ gain and 60fps blue with 95% gain - this is with histo values of 45%-50%.....Saturn is around 0.6 magnitude at present and in the morning murk there was no chance of ramping those up to some of the frame-rates we could employ last year!

A pity 'cos the conditions meant high fps might've proved usefull - they were such that focusing was a bit like chasing shadows tbh.....you think you're getting nearer focus as the seeing improves to provide a sharper image but in reality you're moving away from focus because the seeing is shifting so rapidly & erratically - when you go backwards it is the same problem...these circumstances can be very frustrating!

After the 2nd rgb set the seeing went to muck although we did shoot an iR742nM capture that managed to garner enough frames for an interesting image...I've made a Polar Projection of this capture also to elicit as much as could be discerned of/in the NPZ "hex" although this is very problematical despite being pretty mild with processing application...hopefully tomorrow morning might provide something more!

The iR742nM image

Darryl,

Great opening shot! I very much look forward to your images. It will be a fun season coming up with both Saturn and Mars.

Thank you very much Pete, Pasquale, George, Michal, Christophe, Paolo, Stuart & Max.....most apreciated!

Stuart, I think the elevation was in the high 30's...but I haven't confirmed this yet.

We captured again this morning and "perhaps" the results might be better..?

With the tilt so pronounced we'll be getting some very good vistas of the NPZ & "Hex" this apparition and in fact the iR742nM above does seem to exhibit a pronounced "dark spot" near where the centre/vortex of the NPZ should be - as I said above it is problematical because any exhuberant sharpening creates an artefact that can give people the impression the vortex is in images, but this stack seemed to show it there before much sharpening at all and I was even milder with the processing below.....only time and better seeing conditions will tell but I'm confident we'll easily pick up the vortex later in the apparition!

Here is that milder processing annotated.

Mo, awesome first Saturn set! Banding looks great not to mention the hex clearly visible, very impressive for this early in the season. I am looking forward to your upcoming Saturns which were unbeatable last year. Thanks for posting and good luck with the seeing

Regards,
Steve

KMan, you're out of the gate for this season with a great start! Cheers to a good Saturn season.

I'll admit I've ignored my favorite forum too long now and have been slowly trying to get back here more and more. In my absence have you guys forgotten about Mars or is it to low in the sky for you in Oz?

Mike

Very nicely done indeed, Darryl It's nice to see Saturn turned out like that, I look forward to catching it with the rings at this inclination...but it will really be a southern hemisphere show again this year. Thanks for the encouraging shots, you and Pat rest up...

Clear Skies,
Brian

Thanks Mike, Mert, Brian & Mark - much appreciated!

Mars is starting to ride fairly high in the morning sky down here in South Oz Mike - maybe getting to around 50 degrees or so at opposition.....we should start targeting him soon and although I followed him down to sub 5" diameters from the last apparition I don't seem to have as much enthusiasm to start imaging it yet!

Maybe the 11000km+ trip for Jupiter recently or the allure of Saturn now, which I think rises to about 70 degrees - but we'll definitely start Mars imaging soon.....I do have another "life" but even I'm trying to remember what it is lately!
