mih

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

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?

Yeah, I've gathered that, but i'm curious about the strengths of a refractor. I will get a larger dobsonian as well eventually. The one I have seems to be decent, but you know, bigger is better.

My budget is about 1200 dollars. Hope thats enough. Maybe even 1400. Did you ask me for the budget to do the looking for me? Cause you would be a god

I think might buy refractor because of its portability, so i can go camping ans stuff and stick to the dob i have for now.

I probably will, but i want to get to know refractors as well. Also, there are people saying refractors are good for DSOs, other saying they re not, idk what to believe

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

Right. I found an Achromatic refractor AR152 AIR-SPACED Doublet, 988mm focal length. Thing is it is not ED Its from Explore Scientific

What is the optimal focal length for an ED80. I found one with a 600mm. Is that good?

Oh, sorry, ill check it out Edit: Thanks, i must have overlooked it. Great explanation!

Sorry, i am a bit confused. What is an optimal focal length, or focal ratio for a refractor, since i am seeing a lot of big ones, a lot of small ones, i dont know what i should look for

Thanks, i'll check it out!

Also @mikeDnight, do you recommend an achromatic one or an apochromatic one?

Thanks, i think i might consider buying one after all, you convinced me! I might need to save some money for a very good one. I'll buy it without the mount, which i'll buy separatley, since i want it to hold my reflector as well.

is a refractor a good tool for DSOs? Or is it better for planet viewing?

So you reckon i get a refractor?

The more you know

By ED you mean an apochromatic one? Does Extra Low dispersion mean that when light passes through the lenses it does not go in all directions as much? Edit: Ok, so ive looked it up, so the chromatic aberration is gone

Yeah, i will also get a good mount for the reflector, but want to check out a refractor as well. Maybe ill compromise and get a mount and a refractor with no mount

Ok, thank you so much!

Thanks! I wanted to buy an eq mount, so i was thinking maybe i could get a refractor on an eq and put my reflector on it as well. Is that an option?

I dont know, just asking if a refractor would have any advantages. Also I dont plan on buying it right now. In the future maybe. Sorry for saying that in the description. Or what should i get if I ever want to upgrade in the fiture

Hi, i want to buy a refractor, equatorial mount. I already have a 6 inch Bresser Newtonian, f/5(750mm focal length) with two eyepieces, one 9mm and one 25mm and a barlow 2x and solar filter. I am seeing all these apertures like 90, 100, 70, while for reflectors like i have that is pretty low. Of course, for refractors, the focal ratio tends to be higher. What do I look for in a refractor? I want to be able to see some deep sky objects and planets. I am very confused, does the low aperture mean you gather less light and see worse? What does the focal ratio indicate? I just want to buy a good refractor, or maybe another reflector woud be the next step? Let me know!

Ok, then i want to ask about the Orion Nebula. Is that easier to observe?

Hi, i have a 6 inch newtonian, 150mm focal length(f/5), 25mm and 9mm eyepieces. I currently have observed M13(Great hercules cluster), but you know, its a fuzz. i have a 2x barlow on the way. Will that 2x magnification(83x -> 167x) make any difference?
