A whole different animal

While I will most likely never part with my refractors, the little mak has earned my respect and it's place in my arsenal. I have more than gotten my $400 dollars worth! And my back has not complained in a long time!

Not the best scope out there, but there's very little available that's so light, so easily mounted adequately, and easily moved out the door... for the price.

It is the same with SCTs. Per inch of aperture, they have to be bigger to match the performance of a refractor, but they can make a big aperture in a small package.
My EdgeHD 8" is mounted on a CG5 and goes out the door in two trips.
My 6" APO does a bit better on planets, but the counterweight I need weighs more than my EdgeHD8"!
And the total weight of the 6" APO, Counterweights, and mount is 150 lbs! This is almost three times the weight of the EdgeHD 8" and mount.
SCTs and MCTs are highly biased towards packaging and price, and it has worked well. Tens of thousands of C8s have been sold over the decades, vs maybe small fraction of the number of 6" APOs.
Its all about packaing.

Of course, the much narrower field of view was the biggest obstacle to overcome, so I decided to stick with the moon, the planets and some double stars.
They are wonderfully portable for a 5" scope, aren't they? But just because the field of view is relatively narrow, don't give up on deep sky objects with it just yet. Yes, it's not at all ideal for the Andromeda galaxy or the Pleiades, but there are still a lot lot lot of deep sky objects that will fit in the fov just fine. Though I've scopes with both a wider fov and scopes with larger apertures, I still use my Meade 125 PE Mak on all sorts of objects, both near and deep sky and find it does very well within it's fov.

I've also found a well tuned, cooled and collimated 127 to make mincemeat of close doubles e.g. E-Lyrae, Castor, Porrima etc.
Since it's easy to pack, I'm thinking of taking mine up to the mountains this weekend, as we're headed to the Sierras for a Cub Scout "camp". It would be a shame to miss a rare chance of dark skies.

While the image of Jupiter is softer than that of my refractors
I get great planetary views through my 12.5 inch, F5 Dob. However, I have always been tempted to get a good refractor. Maybe some day. . . .
