It looks interesting, but what advantages would it offer over the Skymax 150 Pro from Skywatcher? Has anyone used both? Or indeed has anyone used a Rumak Mak?

I think it is the same telescope reviewed here http://stargazerslounge.com/topic/165013-bosma-omega-mc6-150mm-f12-mak/?hl=%2Baltair#entry1670091

Thanks very much Peter, will have a look now.

I've made many Mak/Cass telescopes, ones over 8" were Rumaks. The separate secondary of the Rumak design, as the advertising says, offers more options for optical correction, particularly for shorter focal ratios.

I have had a look through a friends Bosma version, I took my own std 6" mak down when I went to visit and we did a comparison. The decision on the night was the Bosma was better with a brighter image,  sharpness was also slightly better. My scope is the same as this- http://www.opticstar.com/Run/Astronomy/Astro-Telescopes-Opticstar.asp?p=0_10_1_1_210

so not the skywatcher 150 pro.

As a visual astronomer I acquired this telescope in May of this year mainly for planetary work, however I have had few opportunities to put it to use, now that Saturn is setting but I shall certainly be setting my sights on Uranus and Neptune this autumn until Jupiter is back on the scene. I did manage to catch a glimpse of Saturn with it one night back in June but the light evenings together with poor seeing conspired against me. Still its performance on double stars is noteworthy. Unfortunately I have not used a Skymax 150 or any other Maksutov design to offer a comparison.
