Refractor specs

What are you trying to achieve with getting a refractor?

If you are wanting to go after DSO ,especially faint fuzzies . Then its aperture is King, and this is where a good aperture Dob reflector is best

If you want a scope to produce sharp clear crisp images of double stars, planetary, Luna ,this is where a good quality lens Ed refractor comes in.

I purchased my Eqinox 80 mm for £250. It has a focal length of f6.2. An older but very good Celestron C 80 mm is f6.5 and do come up as good used at times.

I am a visual observer so the Equinox performs very well. Resolves stars sharper  than a Newtonian in my opinion. So the combination of an 80mm ed refractor and a 150mm Newtonian would allow quality viewing with the ED and brighter deep sky viewing g with the Newtonian. My opinion.

Yes, i am quite a bit. Which one of the two would you say is better in general? The ED80 has a focal length of 600mm.

I think I would be ok with the planet problem, i think DSOs are what interests me

There are numerous books that are dedicated to deep sky using a 4" refractor, so here are some. Also, many amateur observers keep observing logs and sketch books full of their observations using such instruments. Just a handful are piled up in the attached pic. So deep sky can be a great source of entertainment and interest using relatively small refractors. I've also attached a couple of sketches of Messier objects made using a 100mm refractor from the suburbs of a north England town.

Thanks, i will for sure check the books out. I think i found a refractor that fits my needs. It is a SkyWatcher EvoStar ED-APO 100/900. Sounds good?

Yes, my opinion as well. I found a SkyWatcher EvoStar ED-APO 100/900 at a reasonable price. I think I will settle on that one. Its 870 dollars, so its is in my budget

I think a 100ED would be an excellent refractor starting point.
