Thanks, Mitch... "fmhill"
Quote:My suggestion is to go to the Refractor Forum and look for the post where this guy bought a 6" APO and is not complaining.The title of his Post is something like "6" APO is not good for wide field imaging."Duh.See, the requirements for imaging are very complex. You think you want to image, but the big question is "What do you want to image?"The EdgeHD will be good for smaller objects where you want a bigger image scale (small nebula like the Ring Nebula and small clusters). It will also be excellent for planetary imaging even with inexpensive color web cams. At f/2 with Hyperstar, it can also do wide fields, but this adds a lot of cost because of the special camera, or you can get the focal reducer to go to f/6.3, but this is also expensive.The smaller refractor will excel at very large targets like large diffuse nebula and large clusters, but you sacrifice image scale. You should also look at your budget for cameras and things like focal reducers.These are two very different scopes when it comes to imaging (for visual also, but that is another story).Here is one suggestion I often give.Right here on CN, there are forums for deep sky imaging and for planetary imaging.Spend some time looking at pictures and ask yourself "Which of these look like the kind of imaging I want to do?And when you have found them, look at the kind of scope that was used and you have your answer.Otherwise, your answer will beOh, the EdgeHD 11 is betterorThe ES is better.Both of these are excellent telescopes, and most people would say that you can't go wrong with either one.But ask the guy with the 6" APO in the Refractor forum about that. My guess is that he will tell you that you can indeed go wrong.Figure out what you want to image, and buy the best scope for that.Or we may see a thread in the ______________________ forum that __________ scope isn't good for imaging __________.And that would be sad.
