About this product

Model:  promak180ota
Part Number:  10217

Optically this telescope is superb with high resolution, high contrast and almost zero chromatic aberration. For lunar, planetary and double-star observing it is hard to imagine a better telescope! 

"Globular cluster M13 in Hercules was impressive, with multitudes of stars crowding its centre and the famous dark feature known as the Propeller easily visible. The double star Albireo (Beta Cygni) was a treat with its golden yellow primary and pale sky-blue companion in the 20mm eyepiece, while with the 9mm eyepiece we were able to split the tight triple star Iota Cassiopeiae before morning twilight overcame it.  Saturn was lovely, with the Cassini Division, a dusky band on the disc and a polar region all on show. We also saw several of the brighter moons in spite of the planet's low declination by swapping in our own 26mm 1.25-inch eyepiece and boosting magnification with a 3x Barlow lens."  Paul Money writing for 'BBC Sky at Night' magazine Sep 2015. 

Please note: Large Maksutovs should ideally be stored in a shed or garage so their optics are always close to ambient temperature. Stored this way they can be setup and be ready to go in only a few minutes.

Skymax 180

I have always tended to use refractors for imaging. I like the sharp focus and stability which avoids regular collimation. I' have a owned a couple of 150mm APO's in the past and still have images to compare this scopes performance. Although only one imaging session so far and not in particularly good seeing I am very pleased. Side by side comparisons of the lunar images produced put this scope of a par with the APO's. Given the seeing was not good, I think with longer time to cool down and a steadier atmosphere this scope will do better
It sits on an HEQ5 well and is easy to handle.
All in all, I would recommend this to anyone interested in imaging the moon and planets.

Lovely made piece of kit, long 4 month wait but it finally arrived! Sits well on my NEQ6 Pro mount and this is the mount to use for this ota. The only bugbear I have really is if you have lots of accessories like a 2" diagonal and eyepieces in a 2" Crayford dual focuser it has to sit quite a way forward in the saddle clamp to balance the tube and for that reason I would recommend upgrading the saddle clamp to the ADM unit which I had already done whilst waiting for the scope to arrive. Not had a chance to try it as yet as it only came yesterday and as usual in the UK the weather has decided to turn for the next week or so!

I got mine second hand but in very good conditions, I really like it, This telescope is very solid and well made, the optics are very nice and I compared it side by side with my Esprit 150 and I find that it is very close and gives very sharp details and nice contrast.
Although the focal length is very long and ideal for planetary I found that it gives very nice view to some deep sky objects, the Ring Nebula looks really nice even from a very light polluted location.
Recommended indeed.

Skymax 180 pro black diamond...the poor mans 7" APO

I have owned this telescope for about 5 months now, i mount it on my EQ5, just at its limits, now upgraded to CG5 tripod so more stable, the OTA is 7.8 kg!

It is supplied with a 2" diagonal with 1.25 reducer, i found the 2" diagonal seemed to "droop" so i now use a 1.25 dialectric in mine, it comes with 9mm and 20mm ler eyepiece`s, i sold them on!

If you want to get this superb OTA allow for it to cool down before it gives its best, some people think it takes 3 hours to cool, rubbish, just keep it in a cool place, simple.

There were reports of mirror flop on early ones, when focusing, i have not noticed this problem on mine, unlike the omc 140 it replaced! Focus is very good, it snaps to focus very sweetly

The 180 pro gives fair to good views on larger dso`s, but this is not where its at, this is a planet/lunar scope, you just dont buy an OTA with 2700mm focal length for deep sky, viewing Jupiter with this scope is amazing, so much detail to be seen and as for lunar, well you wont find any thing better with out spending a lot more money.

My main eyepiece i use is a Baader genuine ortho of 18mm, this gives a very useful x150 with very good eye relief, if i need more magnification i just x2 barlow to x300

The 180 pro is gaining popularity with the planet/ lunar fraternity, and rightly so, 2 years back this was my dream scope, my dream came true!

Ordered this telescope for planet and lunar visual (and a little imaging) work. Great packaging, arrived quickly and once unpacked was up and running in minutes.

Jupiter and the 4 moons easy to see immediately with the supplied and OK 1.25" 20mm eyepiece, even better once the scope had cooled down (supplied 9mm is poor). With better eyepieces, the coloured bands of Jupiter are clear, GRS and dark barges easily seen. Moon transits across the surface are as clear as day.

Lunar work is amazing, you can easily spend hours looking at details with this telescope. Image is very bright for lunar work, so consider a moon filter.

Being f15, DSO objects are not as distinct as through a big reflector, but they are still there and with good contrast. A lot of people suggest this telescope has similar image quality as some ED refractors, and I would have to agree.

This telescope now has a 2" back, so easy to fit camera etc. to the back of it.

Provided eyepieces and diagonal are OK but you would want to replace these very soon. An aluminium hard case is not available for this OTA (unlike most of the other OTAs) which is a real shame.

So to sum up. Great telescope but let down a little by the mediocre accessories and lack of a hard case. Would have been 5 stars but because of this, only a 4.


FLO site now states that this telescope is now provided with a 2 Di-Electric Star Diagonal and a 2" 28mm LES eyepiece. Their site said this when I bought mine, but I actually got a lower quality diagonal and two 1.25" eyepiece(20mm and 9mm). Take a lookie please chaps
