Hi,
I was planning to acquire a telescope, btw my first telescope, so far i have just only used my camera lenses.
I own a ZWO AM5N and an ASI 2600MC and i already have a guide telescope and camera asi120mm.
I was planning to acquire a ZWO FF107 + autofocuser + off axis guide adapter.
However i noticed that near the city i live someone is selling in "mint condition" an Skywatcher Evostar 150DX + focal reducer ( 0.77 reducer/flattener f6.2 ) .
The evostar + reducer and the zwoff107 are around the same price tag.
My understanding of telescopes is quite limited. So from the specs i do notice the ZWO is a cuadruplet while the Evostar is duplet.
Also there is a considerable difference in focal length 750mm for the ZWO vs 1200mm for the Evo.
My goal would be to have some kind of "all rounder" telescope mainly for DSO/planetary astrophotography 90% of the time and maybe observational for the rest.
According to the manual the AM5N supports up to 15kg without counterweight and 20kg with it, the Evo weights around 10kg.
So the advantages of getting the Evo as far as i can see:
extra focal lenght,
being nearby is avoiding customs and any delivery issue.
The possible disadvantages:
aberations for astrophoto being just a duplet?
backfocus issues?
size/handling?
any adapter needed to mount my camera or possible issues?
any other?
I couldnt find too much info about the Evo. So if anyone could give me some advice, would be very happy.
thanks!
