Hi,
After using the Skywatcher 200pds for a while (really dislike collimating it), I want to have a relatively portable refractor (compared to the newt) for mainly astrophotography. I use a modded canon70d, but plan on getting the imx571 cooled cam. I want to stay under 1000€, but if there is a bargain that could be made I could go to a max of 1500€, it needs to have a aperture of at least 80mm (4") and a fl of at least 400mm (without flattener/reducer) a faster scope would be appreciated coming from a newtonian. What would you guys prefer/recommend. I have the following scopes in mind, feel free to recommend other ones if they are better/more suitable to my criteria.
TS optics Apochromatic refractor AP 80/480 ED Triplet Photoline OTA = around 800€ without flattener
Tecnosky ED Triplet 80/480MM F/6 V2 = around 750€ without flattener
SVBONY SV550 APO Triplet Refractor OTA 80 F6 = around 900€ with flattener and guide scope
ts optics Apochromatic refractor AP 80/480 CF-APO f/6 FPL55 Triplet OTA = around 1200€
Tecnosky 80/480 mm FPL53 Apochromat - OWL Series = around 1200€
Askar 103 without flattener = around 1300€
SVBONY SV550 APO Refractor Telescope Apochromatic Triplet 122mm F7 = around 1500€ without flattener, cheaper during deals
All of these are triplets (either FPL51 or FPL 53/55 (almost the same specs)).
Thx in advance
