I have a situation which I need some help with. I have a 103s and 81s and I'm wondering what the benefit of having both is. The reason this is tough is both scopes are quite similar. Even though the 81s is smaller, it's about the same for me mounting it up on my Vixen Porta Mount (with wooden legs and an extension). Both come to zenith.
I'm having a hard time imagining needing both. Both have near perfect star tests and perform the same.
The only difference is my 103s has a moonlite and the 81s has the original single speed focuser. I have a reducer meant for DLSRs which will only work on the 81s. I don't currently do astrophotography and I am unsure I will ever want to. I did have this up for sale, but realized the focuser pinion needed replaced and I took it down. But now I have that fixed but was unsure if I should put it up again (well, let the dude know who was interested). With my Vixen GPD2 which is upgraded to GOTO with a SynScan I certainly could give DSLR imaging a try. But quite frankly I'm not even sure I could get a real polar alignment done and my DSLRs are older Nikon ones (D40 and 3100) which are probably not great for doing AP. My patience for learning and doing something like that is low. Which is why I enjoy night vision astronomy.
I do night vision astronomy, but these scopes have higher F-ratios and are more used for planets and ultra wide fields (well, wide for my situations). They are really good for 3 degree+ wide fields with my 34mm 68.
Can you think of any reason to keep the 81s? Because of the fixed dew shield and F7.7, it's not exactly portable. I can say with certainty it's extremely good optically though. Just can't think of a reason where it would be needed. It's slightly wider FOV, but not sure that's enough to keep it. Seeing that I have so many other scopes that fit a purpose. The 60mm being my ultra portable setup. The two newts are night vision and the 10 inch is my deep space setup. The 8 SCT for night vision small objects. The 90mm mak is my solar observing setup (the filter does work on the 81s). The 103 is my main refractor for planets, wide field, etc.
Thanks for any suggestions.
