Yes, with small scopes. It depends on what you mean by most scopes. If you mean under 6"

I don't have 10" scope but my 9.25"Refractordude wrote: ↑Tue Oct 05, 2021 12:45 am Found this image on the WWW. Looks like a 6 inch comes close to brightness as a 10 inch. This is surprising to me. Has anyone ever compared a 6 inch against a 10 inch aperture scope? Left click the image.
But let's consider 'as you can handle' part. 10"

Re: What Do You Know About This DOB?
This, unfortunately, is the dilemma faced by all users of telescopes (both visual andBigzmey wrote: ↑Tue Oct 05, 2021 8:20 pm But let's consider 'as you can handle' part. 10" DOB is substantially larger, heavier and more time and hustle to set up compared to your 6" frac. Since it is truss design it will take even more time to setup than solid tube DOB. For every user there is a limit in how much aperture they can comfortably handle, at certain point it becomes too much trouble and the scope is sitting unused in the closet.
Basically, once you figure out the routine needed to set up that particular scope it will either wed you to that scope or drive you to a different size/configuration.
In essence, be prepared to buy another telescope!!!

And everybody's personal answer is based on their own unique local factors. It is not something that neither you nor I can predict. But getting them to think about it is half the battle. Thanks Andrey.
