Looking to buy my first MAK. 6-7” is about as big as I want to go. I’m leaning towards the 150 or possibly the 180mm from Sky-Watcher and was wondering how they perform or are there better alternatives from other makers at that price point ?

I intend to buy the 180 as my next scope for planetary, it gets good reviews, especially the newer versions. There are at least two threads that give a lot of info on it and compare to other telescopes. If nothing else put Skywatcher 180 Maksutov in the search box.

Definitely buy the SW 180 mm mak - they’re a bargain. It’s big enough to show DSOs as well as doing very nicely on mom and planets.

The 150mm is good as a grab & go if you have a significantly larger scope, but if it’s your only scope you will soon lust for something larger.

well.....I decided to forgo the SW......after doing a bit more research I went with the Ioptron MAK 150. Everything Ive read about them points toward a better scope...we shall see I guess LOL :)

No, SW 180mm id the best, you lost something, but it is ok, you will be fine or happy with what you get but you don't know what you are missing, if you have time and it is not late yet you can return it back and go with 180mm.

I have examples, but i think i am not a known respected member with results here, so maybe my examples won't be enough for you to change your mind, i am trying to help you to get the best, but sounds you made your mind already, so now i have no choice here but to wish you all the best with that scope, show us results later.

 

Clear skies!

I think the IOptron 150 is a good choice, it's a Rumak variant with excellent field correction. Not that the 180 is terrible. Too bad IOptron doesn't make a 180, best of both worlds. The added aperture is nice, but the Synta 180s are very good, anyway. It's part of the trade off. The IOptron (likely) has better field correction, so you cannot go wrong with it, either.

I have the iOptron, it is very good. The long FL of the 180 kind of put me off. Any scope that cannot show the double cluster as two clusters is probably too much FL for me. Plus such a narrow FOV puts a lot of demands on your GoTo alignment. Last time out with the 6” I forgot and left my 42LVW at home. Kept having problems with GoTo placing targets just outside the FOV and thinking to myself that the targets would be in the FOV with my 42lvw. Also thought to myself that I would probably have similar struggles with a 180 even using the 42lvw. Now if you use polemaster to do a precise polar alignment, then sure, get the 180. But if you just rough polar align like me, having a little wider FOV helps the GoTo work better. In addition to being able to frame double cluster, M35, fit the seven sisters (not the entire Pleiades cluster), etc. I mean, can you even see M81 and M82 at the same time with the 180?

So I went with the iOptron as it is a bit more versatile in terms of being a good planetary scope and being good for brighter DSO. The 180 is probably more of a true planetary specialist with its smaller CO, but the long FL concerned me for DSO. The build quality is also excellent on the iOptron, except for the finderscope. Dual speed focuser, nice aluminum dew shield, Rumak design.
