Every few years out here on Cloudy Nights, I see someone post topics on Planet Killer telescopes.

With the Mars Opposition this year, and the conjunction of Jupiter and Saturn, I thought this would be a good time to stir up the excitement by asking what is your planet Killer scope this year, and post some cool photos of it.

I choose the refractor forum to post this since refractors seem to be the telescope of choice for "backyard" planetary observing. Sometimes, refractors are purchased to just enjoy the Moon and planets. While I don't agree that refractors are the best choice for planetary observing, they are easy to access and popular, and inch for inch, they put out the sharpest views compared to their reflector cousins.

For me, my planet killer has always been my largest scope, this should be my C11XLT. Having admitted this, in late 2018, I purchased a new APM 152ED refractor. 2019 was probably the worse year for planetary observing for most people, so I've only had one good night with excellent seeing conditions to confirm that the my new 6" refractor definitely qualifies as a formidable planet killer scope also.

I like refractors best. I like how they present the sky to us, and I like their slick looks also. I want my new 6" refractor to be my first choice whenever the skies are clear and the planets are out.
So for me, for 2020, I am calling my 152Ed my new Planet Killer.

I'm hoping its the TEC140fl that's on order.  Scott

Hope it will be the Mewlon 180 C, when collimation issues are fixed...

I'm definitely all on board with the Binoviewer when observing planets.

Most the most part it won't be one of the telescopes I own but rather the 17" f/15 classical Cassegrain at the Naylor Observatory. 

 

I've included some recent iPhone photos.

My backyard planet/double star killer:

 

StarSplitter with Drum Fan.jpg
 
Refractor wise, it's my 120 mm Eon. It qualities as grab and go.. if I want more zoot, it's my 10 inch Dob.
 
Eon Number 2 Backyard 1.jpg
 
Edit.. From our place in the desert mountains, the seeing is generally not great but the 22 inch still provides some amazing views.

I'm pretty anxious to find out how much my APM 152 ED can show on the planets. So far, since I got the scope, they've basically been unobservable from here at 55°N. I'm crossing my fingers for decent seeing during the Martian opposition. Saturn and Jupiter will both be very low in the soup and will most likely not be much to look at.

It looks like Mars will be about 40° elevation for you at opposition. That's definitely got potential.

Well I picked up a 150 mak, so I’m going to try that out. If not, it will probably be the 120ED I’ll pick up again before summer if we get this house we’ve been working on getting.

Indeed! Especially since the period prior to opposition itself happens in the time of year, when we usually have the most clear skies and the steadiest seeing. By mid-July, it will already be above 20° latitude in the early morning hours and have a diameter greater than 12"! 

 

Jupiter and Saturn will both max out at around 12° altitude... Glad I have a low horizon to the south.

I understand the value of aperture in planetary observing but I'm looking forward to using this one for that purpose. Its lunar performance is exceptional.

1200mm refractor is about the longest that is convenient.

A Celestron edge 11 would have a bit more fine detail resolution and longer (3X) focal length for more power.

But the refractor is sweet and simple.

I have the APM 152ED and a APM 140ED. The 140 is easier to handle physically and a better imaging scope - the 152 is the better visual scope. Probably going to sell the 140 to fund an imaging triplet and keep the 152 for visual fun (maybe some imaging on smaller targets also).

If a person wanted a planetary simple refractor of limited aperture the Altair Astro 102mm ED F-11 is very appealing for a good price. It won't have the fine detail resolution of a bigger scope, but it would be a good choice for someone limited in funds and size (for visual - as in outreach use). Wish they made a 120mm ED F-11, now that would be something. The Skywatcher 100ed F-9 is pretty good too, but the skywatcher 120 at F-7 would be a real planet killer at F-10/11.

The one I would choose as my favorite would be the Thomas Back (APM) 130mm LZOS F-9.25 triplet, but sadly it is out of my comfort price range - one can dream.

Do you still have your 102 F/11ED, that should be a pretty nice planet killer also.

Mine previously was a 6" ED and then a 7" ED but I confess that I'm now on to larger OTA's as the added brightness (colors, Etc) trump all the excellence a Refractor brings to the table.

I'd be on the waiting list for a 120mm ED F-11, definitely!!

I will still use my dob, but I purchased a 127 Mak and binoviewer to use almost exclusively on planets this year.  So far, I've only used it once or twice on Venus in garbage seeing conditions, so the jury's out on whether it's a "planet-killer" or not.

 

While I await the planets, however, it is proving to be a great lunar scope. waytogo.gif

So, as subject topic suggest, we have to kill some planet this year again? frown.gif

And we only have eight left to be killed.... I really prefer observing them than killing them. smile.gif

Anyway, many consider we have already start killing the most important one... Earth. blush.gif
