“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:As far as I'm concerned...it's great to have both. A big newtonian and a small to medium apo refractor. Then you cover all your bases.

Quote:Inspired by many discussions I've seen over time about how aperture is king and how the impact of the central obstruction on other designs is overstated, I am curious why people spend the extra money on refractors.Consider that you can get an 8" f/4.9 newt from Orion for $300. You get the relatively wide field of view, no CA, and a lot more aperture for way, way less than even a no-frills 5" ED doublet would run. Heck, throw in the coma corrector too, and you still don't even come close.I can only speak for myself, but having owned a Newt, and SCT, and now refractors, I find that there is a certain visual aesthetic that decent refractors provide. Very sharp images, high contrast, no diffraction spikes. Bonus: no messing with collimation (not hard, but convenience is worth a lot to me since my observing time is limited... and I might just have two left hands [I'm right handed ]).I'd love to hear your reasons.

Quote: Have you ever been in a dark sky with a 10 inch telescope? A 16 inch telescope? A 30 inch telescope? I have...and they were not refractors. Did they have disadvantages? sure. But when you can count a ton of Saturn's moons, see crazy views of galaxies, nebulas taking on a whole new meaning, color in planetary nebulas, Globular clusters shimmering like star dust...it's something special.

Quote:There is no debate over the "right tools for the job" philosophy. The debate comes in when anyone from any of the astro sub-sets claims that his/her scope is "better."
Quote:The biggest puzzle to me is that in the hobby SO many people are more than willing to share access to their scopes at SP's and many people with these type questions don't take advantage of it. A star party is a great place to see many objects, and objectives. If you find at the end of the night you want to take home more than one of the instruments you looked through, you've found the answer.
Quote:...pinpoint stars, no messing with collimation, quick cooldown times. I imagine at some point in the future I might once again add a larger dobsonian to the mix, but for now I just don't think I would use a dob enough to justify the expense.
Quote:the point is..it doesnt matter how big your scope is, because all of them show basically nothing.
its only a question of how much you need to see to be satisfied.
Sex appeal with telescopes? That's a new one for me. I mean, among us I agree. But I can tell you that non-astro people are more impressed with my 10 inch (insert joke here) than my sexy apo.

Quote:aperture is king, yes, so you get the biggest refractor you can....seems simple enough
Quote:How do you like that GEM? It look really cool, and seems affordable for what it's capable of doing.
Quote:all these contrast/ resolution arguments are meaningless if you compare a refractor with a reflector of double the size. the reflector OBLITERATES the refractor.
Quote:do you have the polar finder scope which screws into the middle of it? I'd suggest it if you do not. It makes a big difference for getting polar alignment correct. And it's pretty cheap.That's a nice photo...it's hard to get the trapesium balanced. I personally have skipped astrophotography for monetary reasons...but I enjoy looking at the photos of others.
Quote: Make no mistake here. If you want to see more structure or detail in any kind of extended target such as nebula, galaxies, or planets, there is absolutly no substitute for clear aperture.Almost all of the design discussions totally omit the function of image brightnss/image scale that is offered by a larger aperture. We tend to discuss equipment like we don't have eyeballs.
