Was there not a planet wide dust storm on Mars last opposition?   I recall just a blank orange martian disk in my 155 f/7 edf.

I didn't get to see Mars last opposition due to the timing of our Monsoon. But, as I recall, yes there was a pretty significant storm that lasted quite a while. Folks were complaining. lol.gif

 

Below is probably my best overall view of Mars, almost saw some canals. smile.gif

I have two Newton scopes, a 24” f5.4 dobson and a new atm 10” f7 (Zambuto quartz) soon to be finished. I have also a Baader MkV bino combined with either Baader FFC barlox at 4x or a dedicated glasspath corrector 1.7x. And SIPS but with mono eyepiece of course.

 

Waiting to compare those two scopes on the planets, side by side.  Uranus and Neptunus are also high up in the comming fall.

I will be using 3 scopes.  TEC 160 FL, Lockwood 12.5" f/6.5 Dob and a C11..  At different times over the July to November 'window'.  And at numerous locations.....  

 

I hope to make many sketches of the details I see.  Perhaps i will be able to discern which of the three scopes provided the most detail the most often.

Nice to see a few V8's out here instead of the smaller 4 or 6 bangers. Astro Physics is still the King!!

Indeed!  The rest are just... amateurs. ;-)

I'm back in the southern hemisphere and well north of the southern jet stream. The seeing should be good except that October tends to bring a lot of rain... maybe an expedition to the desert is warranted.

 

On scopes - I've just started a 10" f /9 that will be built roughly along Ed Turco's Definitive Newtonian. The trick will be finding local glass for a 10" window. (Failing this, I'll use a spider until I can get glass.) Since it's intended for shallow space observing, I'll build in an integral Barlow and achieve something like 3500-4500 mm effective focal length. My 16 mm ZAO II's seem to be perfectly suited.

 

The problem with a scope this extreme is the distance between its mirror-end and the eyepiece - probably close to 86". There's no way I want to stand & make critical observations, so I'm thinking about digging a pit for half the scope to hide in.

 

However I finish it, I'll be interested to see how it shapes up against my TOA150 (this is refractors after all!).

 

Edit... how could I forget, I have the keys for the 26" refractor up at the observatory. grin.gif

Well for this year I am using a telementor (early one). I have been fortunate enough to own and use many TMB and Takahashi refractors including a TMB 203 F9. I am "inbetween" scopes but really enjoy the little zeiss right now.

Forgive me if this is hijacking the thread, but I'm SUPER interested in planetary viewing and didn't realize binoviewers were a great choice for planets! What kind of a difference does it make? On a 12 inch Dobs, and on an 8 inch SCT would it be worth it?

It make a profound improvement for me.  It is definitely worth the investment.

Without getting technical I will say that I almost exclusively use binoviewers for everything since using them for the 1st time......everything is improved by using both eyes IMO. That said I cant speak for the inexpensive ones but a good set of quality ones with good eyepiece pairs and a power slide has totally changed my viewing preferences. Preferably on scopes that are setup for using them without an OCS.

 

I have not used my C11 or my 8" refractor without them since trying it. That said I dont use them with anything under 6" as I find it dims the view too much for my taste particularly if you must use an OCS to achieve focus.

looking into getting my first Dob  for planet season  have a line on a possible 10 inch f-8

long tube at a good price     

 

meanwhile     the fs-128  is no slouch on planets

I wanted this for years - Sir Patrick Moore's Cooke 5 inch F/12 achromat:

But as that was not available I put together my own version - TMB/LZOS 130mm F/9.2 smile.gif

As long as you don't have any eye issues using regular binoculars, they are the best accessory for planetary viewing imho.  Observe for hours without eye strain and see more / better.

Even inexpensive plossls in a well made binoviewer give more pleasing views then one single very expensive televue 100 deg eyepiece. The differences aren't even close how much better your brain processes the information you see.

As long as the seeing conditions are good and your scope is acclimated to the outside conditions, the binoviewer views always wins.

Yep, that's what I said "... seeing is always critical ..." Jealous? No, I'm content with where I am; there's always going to somewhere better or somewhere better with a better telescope, too. And yes, optimize the best scope one has available for the task at hand and make the most out of it.

We are already killing one planet. Do we need to kill other ones?

You never know, we might actually be making it better overall.  There seems to me a collective pre-disposition that everything Man does is bad.
