I have a very nice stellarvue svx 102t on order. I got a bigger mount than anticipated, and I'm already thirsting for something larger. The 102t is already expensive and very nice, but now I'm having doubts if I should just cancel and put in an order for an svx 130t which is a real dream scope, and wouldn't leave me with doubts if I should have gone bigger.
Yeah there are much cheaper options for big scopes, but I'm kind of locked into the idea of a stellarvue at this point. I could get a completely different 130mm triple for the price difference and probably be satisfied with it (AT/ TS optics), but then I wouldn't use the 102 as much.
The 102t gives me 700 at f7 or 500mm at f5. With the 130 it's 900mm at f7 or 700 at f5.
The other option is keep it and enjoy when I get it, and spend that money on other accessories/cameras and get some sort of big reflector later to go deeper. This is purely for astrophotography, and I would like to eventually be able to get some high resolution shots zoomed in on DSOs that fill the frame to the edges with nebulosity so idk if a refractor will get me there.
+1 to post #9 above. Somewhat more detail here.
Are you new to DSO astrophotography? Then the two scope solution is _far_ superior, moreso than you're likely to think. It's simply unintuitive how much longer focal length complicates things. The effect is far from linear.
The reason is the smaller scope will make learning this difficult subject _far_ easier. Moreso than you're likely to think.
If your goal is to image small targets with a big scope, you'll reach it faster/better/cheaper, if you start with a smaller one, and big targets. Have more fun, less frustration. Be emailing images to your friends sooner.
This is not a close call. <smile> A talented beginner, looking back on his first year. Every word is the truth.
"First and foremost is listen to the folks who have been there. The philosophy of 80MM APO and good $1500-2000 mount is great advice for beginners. Sure you can possibly <learn to> image as a beginner with something that is larger or that you may have but holy cow its hard enough with something small."
Note one thing. I'm not saying it's impossible to start big. I am saying it's substantially better to start small. That's been proven here, over and over again.
