I have a 127mm MAK, and for planets and moon it's fabulous, also for double stars, but for deep sky objects ... weak weakens enough, in my opinion is "dark".
I've always liked the observation of planetary nebulae and I would like to give me your opinion on the minimum aperture to observe these objects with some structure and color, as the Mak shows these planetary as fuzzy stars without color.
I know that more aperture always is better , but want to know with diameter begins to appreciate this.
Regards and thanks in advance.

Quote:Hi DavidWell, he mentions he has already seen a few, as fuzzy stars, and wants to know where they begin to show color and such. I've observed dozens in my 63mm Zeiss, but the brighter ones only really begin to show color to me in my 12". My eyes are fairly insensitive to color, though. Now details, however, is a much more complex question and a potential HUGE can of worms, as I have repeatedly mentioned that it's possible to observe much detail in small, bright planetary nebulae in a small telescope, as long as it has tracking and very high magnification is used. I've seen more detail in planetary nebulae in my 94mm achromat than in any other telescope I own, including my 12" dobsonian. That is because I have been able to use extreme magnification, up to 740x, to magnify the tiny details enough that I could see them. A 5" mak should be able to perform similarly.Clear skies!Thomas, Denmark
