Baader Hyperion Zoom vs Barlow zoom

[caballerodiez91]

Hi there, I have a 8'' dobson focal 1200mm, I'm interested in deep sky - observing and I would like to buy an eyepiece. What do you recommend me?

- Baader Hyperion mark II zoom 1,25''.

or

- 24 or 25 mm eyepiece 2'' + adjustable barlow.

I heard that 2'' eyepieces are better for deep sky, but I want a zoom and I heard there are no 2'' zooms.

Thank you!
Cheers.

For the focal length ranges you're looking at (24mm and narrower), a 2" eyepiece would provide no benefit.

The Baader zoom is fantastic, and includes both a 1.25" and a 2" barrel, if the barrel size is a concern.

If you're looking for a wider fov eyepiece, then you'll likely be looking at a fixed focal length - 32mm or 40mm or something wider than zooms are available in.

My advice would be to get the Baader and a dedicated wide-view eyepiece.

I am not a fan of zoom EPs, they have a comparative narrow field of view. You will get better performance from a dedicated EP. For DSOs, you will want to use 2" EPs. Once found, some DSOs will show better with higher magnification and you will switch to the 1.25" format. I prefer the ES 82s and 68s and would suggest getting 3-4 of these. The ES 24mm 82 would be a wonderful DSO EP for your scope, the 18mm 82 is my most used EP in every scope I have that has a 2" focuser. The 14mm 82 sees almost as much use as a medium power EP, and the 6.7mm 82 is my EP of choice for most high power planetary viewing.

Welcome to the forum! If you can provide the list of EPs you already have we will be able to advise you better. DSOs come in wide range of brightness and sizes, so there is no one 'do it all' EP.

Well, yes and no. Widest FOV you can achieve for 24mm in 1.25" barrel is 68 degrees. 82 to 100 degree EPs would require 2" barrel. I feel 68 degree is good enough, but many people prefer 82 or higher. In fact Explore Scientific 82 degree 2" 18 mm reported by many to be great for galaxy hunting with DOBs.

Thank you for your answers!

Ah I have the baader hyperion mark II

I understand. So, do you recommend me to get a 24 or 25 mm eyepiece 2'' + an adjustable barlow instead of the Baader Hyperion zoom 1,25''? (please imagine I didn't buy the hyperion xD).

By what you said, I assume a 24mm eyepiece may have a FOV higher than 68º in 2''.

I just want to see deep sky but also want to have everything in one.

I would suggest the ES 24mm 82 2" EP.

Thank you. What adjustable barlow could you please recommend me for that eyepiece?
