As long as you stay with mounts which carry a minimum payload of 5kg the SW 4" fracs shouldn't be a problem. But the Starquest mount is not in this league!

<br />Yes, that's what I'm saying, the Bresser 102/460 xs is a good focusser which can be upgraded with a good lens :-). Guess I already explained my liking for the device. But the point was if the two mentioned skywatcher scopes are comparable to each other and to the Bresser scopes and I suppose so but do not really know. 2,0 kg weight of starquest 102 really is an issue.

I've contacted Bresser Germany before I ordered my Polaris. I was assured that the main lens is the same as the one built into the xs version.

<br />is the difference between starquest102 and normal Skywatcher 102/500 the same as between Bresser 102/460 xs and Bresser Polaris?
So optically I think they're all level.

Hello Dimitry,

you can see more (not only diffuse blobs of M13, M51 or M31!) after only 20 sec exposure(!) with a Bresser Polaris 102/460 Refraktor on EQ3-1 (which you can use either as equatorial or alt-az) for about 250 EUR street-price ENHANCED by a cheap CMOS camera like the SVBONY SV305 for a total of about 400 EUR.

It's called EAA (electronically assisted astronomy). No guiding and tracking required. Software is free and available for Windows & Linux.

Last night I made (albeit tracked) 5sec x 60 frames sessions for M3, M5, M51, M101, M106, M12, M10, M92, M14 during about 2 hours. Sparkling stars, great resolution of the outer areas of the globular clusters and readily visible spiral arms & knots in M51.
