Quote: The attached image is the "Leo Triplet" (M65, M66 and NGC something). Was wondering how approximately large a mirror would be required to see something of similar brightness & detail visually rather than by photography?

Quote:As big a mirror as:1) You can afford that has a high-quality figure;2) Will still allow you to observe at all altitudes with your feet still on the ground (depends on f-ratio of mirror);3) Is within feasible size to transport (both in terms of available vehicle and available muscle power).4) Is within a price range your wife will knowingly approve you purchasing without initiating divorce proceedings.
Quote:Wow, if I could see that thru my future scope, I would be v happy. Still no chance to try things out under dark sky BTW- temp of -25C at night here. Have to become a snow-bird I guess...The Collins looks interesting but I think not at $4K (even if I could purchase it being non-USAian).
Quote:Thanks for that interesting web site Kevdog. Looks like I'm in the purple zone (third brightest) but that was in 2006 (the apparent date of the map) so I'm guessing I am in the red zone now. Will have to get to darker skys when the opportunity arises.Looks like a 16 or 18" might be wasted where I live so I would have to plan on travelling with it - maybe haul it on a small utility trailer and unload it via a ramp?
Quote:Thank you Mitch & Jay. When you say "fabulous" and "great", do you mean as good (or better) than the image?
Quote:Purple is the 3rd darkest area. If you're in purple then you have good skies.
Quote:Try this one as well:http://darksitefinder.com/maps/north-america.htmlYou can also use this outside to get a feeling of your Bortle Scale for your skies:http://darkskydiary.wordpress.com/tag/bortle-scale/Scroll down to the flow chart and follow along.If you're in Orange or better, you can do some decent viewing at home (I know I do). But there's something magical about truly dark skies. But I'm not giving up the nights viewing at home either!

Here in the northern latitudes, Leo Triplet can be seen nicely in Spring/Summer evening skies, don't forget the Virgo cluster/right next to it, plus all those great galaxies by the Big Dipper...Andy
