Quote: when looking near the zenith where the seeing is the best, unlike the F/11+ refractors above (notice how they're NEVER pictured toward zenith?), you won't be groveling in the dirt or straining your neck or having to take out a huge mount that raises it so high it's comfortable to look thru at zenith (but a PiTA to look near the horizon, or move).

Quote: Of course a valid point is that you might not want to go to 150x in a 80mm scope, especially in an achromat.

Quote: And then we get to the ergonomic issues of tube length, wind sail, looking at zenith, etc. And for the record, I have ALWAYS employed chairs in my basic observation gear. Rather than a fancy adjustable one, I own two distinct chairs: one that sits rather low, and one that sits about "normal" height. But I have also had to employ my derrière on the ground when using F/9 and longer refractors, and only such long tube refractors have ever required such uncomfortable groveling in my decades of astronomical observations.

Quote:. If you've never seen the Eskimo Nebula in Gemini in a finder, you're long tube "gun barrel sight" is going to be much less useful than a shorter tube "gun barrel sight" with a wide field eyepiece in the focuser for that "wait a second" moment of catching the Eskimo for the first time in a low power eyepiece.It is important for we more experienced astronomers to listen to the OP. He started the post. Let's try and address his needs above our own predilections.

Kenny, what is this scope?
Quote:Hi ColinWhile I totally agree on your analysis of false color, I must respectfully disagree with you on a number of other points: Quote: But even finding Uranus, e.g., in an F/15 scope without go-to is a difficult task for an experienced observer This is absolutely not true by any stretch of the imagination. First, finderscopes are invented for a reason, second, a long-focus refractor is often long enough to act like a sort of pointer on its own. I've used a 85mm f/19 (1600mm focal length) refractor for many, many years and have always been able to find what I wanted to see (if it was within the reach of the scope, of course). For most things, I just aim along the tube, like down a rifle barrel. This more than suffice for bright stars and planets, and for dimmer targets I starhop.

But I have also had to employ my derrière on the ground when using F/9 and longer refractors, and only such long tube refractors have ever required such uncomfortable groveling in my decades of astronomical observations. Funnily, I have only very occasionally needed to sit on the ground, while observing with one of my refractors, while on the other hand, I always find myself down in the grass, when I want to observe something low in the sky with my 12" dobsonian.
