Mak for terrestrial?

[tico]

Hello, Does anyone use a Maksutov 102 or 127 for terrestrial observation? Thank you ,

What about this? Does it answer your question?

Have done, crazy magnifications. It’ll only take 1.25” ep, so I use a 24mm wide ep normally.  Needs a solid tripod. I’ve flocked the inside of the tube, the secondary baffle and the baffle tube to help the contrast, though it’s still a little less contrast than other scopes.  For high power views it’s a cheap and potent option, though you can’t get low powers unless you accept plossl width fields.

Yes I've done incidental terrestrial with a 127mm f15 maksutov and 45 degree erecting prism diagonal e.g. observing birds at an rspb reserve (Im not a bird watcher, I just sometimes go to nature reserves to do astronomy) or ships in the distance if I'm on holiday by the coast.

It's a lot of magnification and  narrow field of view.

I’ve even used my skymax 180 for terrestrial, with the same 45 degree right-image prism that @PeterW has (William Optics, it’s not at all bad), with consequently even crazier magnifications: the skymax 180 has a focal length of nearly 3000mm. On cool still days it’s perfectly possible, though with a “low power” eyepiece and corresponding too-large exit pupil, the amount of the exit pupil actually entering your own eye’s pupil increasingly gets taken up by the the Central Obstruction, leading to a very noticeable dark patch at centre-view. The same thing will happen with a Skymax 127, I think.

But I have managed to identify a Great Egret with it from my patio at 5km distance.

will this be good enough for galaxies and other deep sky objects? Edit: I found my answer. A 102mm will see many deepsky objects, I am away from lots of light pollution. I am able to see most if not all of the Messier objects, which include many decently bright galaxies. Checking reviews and comparisons might help gauge their value. I highly recommend Academized for their "write my coursework" https://academized.com/write-my-coursework service. They provide excellent quality coursework at affordable prices, and their turnaround time is impressive. The writers are knowledgeable and thorough, ensuring that every assignment meets academic standards. If you're struggling with coursework and need reliable help, Academized is the way to go.
