Heyyo everyone! I am not so new to astronomy and astrophotography. i currently have a 200/1000 mm skywatcher scope, a motorised eq-5 and a zwo 224 MC color. I noticed that the 1000 mm is a bit too big for the zwo 224 and i would like to change not only to a smaller focal length but also an apo scope because of chromatic aberation and all that. my budget is about 600$ but can go to around 800$ if i wait a bit.
I searched on Astroshop and i found these:
Apochromatic refractor AP 72/420 EvoStar 72 ED DS Pro OTA
Apochromatic refractor AP 80/600 EvoStar ED OTA
Apochromatic refractor AP 62/400 Evolux-62ED OTA
I asked Chatgpt and it told me about these:
Orion ED80T CF Triplet Apochromatic Refractor
Astro-Tech AT72EDII ED Doublet Refractor
William Optics ZenithStar 61 APO Refractor
Explore Scientific ED80 Essential Series Triplet Refractor
Now i don't know how good these are because i've never had an apo scope and i don't know what stats i should look for.so i am asking for your help to tell me which one is the best out of all these, or tell me a better variant.
Thank you in advance, George
