Quote: @OPWelcome to CN. My two cents here. You can always buy an eye piece next month BUT you can't add 2" to the primary period. Regardless of the level of the light pollution, location, your experience level 10" will always show more than 8"In my experience and opinion 10" is the smallest of medium sized telescopes and at the sweet spot where visual astronomy become s interesting I am a DSO person. Let us face it. Deep sky is where the fun is. )I started with a 6"...It will show you a lot of planetary nebulae , with the help of a UHC filter some details in handful of brighter ones, fuzzy blobs of globular clusters, brighter galaxies. 8" with proper filter will show details in most nebulae, will resolve all brighter globular clusters, a lot of fuzzy galaxies. Some details in hand full brighter galaxies. 10" is capable of giving satisfaction to even a newbie from light polluted backyard. Under darker sky it becomes a mean DSO hunter into six months of this hobby in a green zone one excellent night I have seen flame nebula for the first time in my life without any filter in Z10. It was my first night under a dark sky with Z10, the nebula was so annoyingly bright i thought i had a smudge in the eyepiece lo lol . alas I didn't have a good chart for horse head nebula handy, that was a perfect night for it. An hour later in a galaxy rich region I had 7 galaxies in the field of view at one point. The problem was not finding them but identifying them
The key to seeing more is not a larger scope but becoming a better observer......Jon Isaacs Z 9.74" F/5 11" CGEM with denk S1 5.5mm, 25mm, 32mm plossl 13mm ethos, 22mm T4, 31mm T5, 35mm panoptic pentax 5xw, 7xw, 20xw, 40xw nikon action extreme 10x50W lumicon 1.25" filters Telecat XL, XLK autocollimator, sarasota, florida

Quote:So I ask the age old question once again, 8 inch or 10 inch? And why?
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
Quote:And an f/4.8 is quite a lot harder to collimate accurately than an f/6.
Quote:, I finally took the plunge and just bought a 10 Apetura. Of course it's been cloudy for a week straight since it got here, but this weekend shows promise.

Quote: To the OP: 10" seemed to be the max size for comfortable viewing with an observing chair, and to physically move the scope around. to me and that's why I got it.
Quote: Ah, then you can go from an 8 to a 12.
Quote: Personally I find the 8" Dobsonian mounted Newtonian is the largest I can easily move about;going to a 10" definitely means multiple trips carrying one piece of the scope at a time.The 12" is hardly more trouble than the 10".Both 10" and 12" really require a wheeled cart or dolly .The 8,10,and 12 were steel tube GSO or Synta makes.
Quote: Quote: Ah, then you can go from an 8 to a 12. One can also go from a 10 inch to a 12 inch. No reason not to.Jon
Quote:Not a silly question if you are new to the hobby.
Quote:And when the author of probably one of the most popular beginner's astronomy book says the optimum aperture is between 6-8 inches for a Newtonian and everyone else online says go as big as you can afford, I personally would like to know the reasoning for each side.
