I open this discussion because I'm really interested on this scope, and I hope it will come to the market soon.

 

It's in the SW Australian catalog linked in the 150 ED topic.

 

http://skywatcheraus...-compressed.pdf

 

At pag 36, but there is just one picture - no spec or info.

 

Here in Europe the 72mm ED is much much more expensive than the version sold by Astronomics in US (650€ vs 460$!).

 

I hope this will be an f6, any more info?

 

Price? Glass? Why not a retractable dew-shield?

The Evostar 72ED will be the small new comer to the Evostar ED line. It has a fixed dew shield, but it can be removed. None of the Evostars have retractable dew shields so this goes along with that line.

The scope is only a couple pounds so very light weight. Dual speed 2” Crawford focuser. The scope mounts via rings and a small dovetail. We do not have the included accessories picked for this yet but it will probably come with a diagonal here in the US and maybe a small finder.

The focal length is 420mm, making this an f/5.8. We are looking into a reducer/flattener for Imaging. The glass is a proprietary ED glass combo.

I do not currently have the retail price for this here in the US.

Thanks! So, this will be a real ED scope, exactly like the 80mm ED but smaller? The weight is incredibly low!

Weight is 4.3lbs for the OTA with the mounting rings installed.

Very Nice Indeed. I have always had a huge interest in these small/fast refractors.grin.gif

This refractor will be available in a few days in Europe,at APM and Telescope Service....I had in mind an 80mm f/7 ED refractor,only for visual,but this new 72mm refractor it's even more appealing.It weights only 2 kg !!!...for me this is very important,since I don't have a car...and also it's 300 euro cheaper than the 80mm ED I had first in mind...But I have a question...how hard will have to "work" at f/5.8 the normal eyepieces like Plossl,Orthoscopic or cheaper UWA eyepieces like Explore Scientific of William Optics ?...right now I can't afford Televue eyepieces...I'm more concerned about field curvature in wide field visual observations...thanks :)

For star testing I use a Celestron Excel LX 2.3mm eyepiece. I used this visually on the moon with the 72ED and it worked quite well. Field curvature wasn't really an issue that I saw but I will have to try it out once the skies clear again.

A 72mm refractor makes an awesome grab & go scope. Larger than those 60/61mm baby scopes.

They are £265 in the UK and the dewshield is not retractable but is removable.

Glass type is not specified but is confirmed to be ED.

Seems a nice little scope to me. Very nice visually and I recently took a couple of lunar shots to see what it would do. Couldn’t really care less what the glass is if it does this !

I too am VERY interested in this scope. Currently selling off some unused equipment to buy a refractor, thinking this may be the one...

I will follow this post too. I am very interested in this little telescope. It seems very portable and with good optical qualities. It might be my first one.

Scopes of this size and quality are wonderful first scopes and/or grab and go scopes on a decent alt-az mount. From my scopes, the small ones get the most starlight because they get used so often waytogo.gif

Let me add my 50 cents here flowerred.gif ,

 

After reading all the messages written about the scope (and here I really mean all of them, it is amazing how much I'm learning from this awesome place) I decided to purchase one, to compensate my SCT's narrow field and mostly for EEA purposes.

Here you have it placed piggyback over my Celestron CPC 800 GPS (XLT):

Telescopes.jpeg

I've already tried it with a 2" diagonal and all my EPs (ranging from a 5mm Kokusai Kohki orthoscopic to a 50 mm 2" SuperView GSO) and had excellent views with them all. Oddly enough, I couldn't make focus with the illuminated reticle one (a Svbony 12.5 mm plossl) but had no focus issues with the rest. I also took some pictures from my (badly light polluted) front yard...

Here you have The Moon taken with an RT IMX290 mono camera (about 1000 frames stacked with AutoStakkert and with some minor retouching made with The Gimp):

Moon-20190112.jpeg

An here of M46 using an RT IMX224 color camera fitted with a Optolong UHC (20 images of 20 seconds each, stretched with FITS Liberator, stakked with DeepSkyStakker, noise reduction by Fitswork and some minor retouching with The Gimp):

M46-20190113.jpeg

In sum, to my understanding, this is a pretty amazing scope waytogo.gif.

I used this little refractor to shoot Sunday's lunar eclipse.

Actually I have a question for you all, if I may: As I said, with the 2” diagonal I could make focus with all my EPs but the 12.5 mm illuminated reticle one. This is rather annoying since that's the one I use for precise goto aligment. Does this also happen to you as well?, would a 20mm focal one do the deal?
