<p>I recently bought a 6-inch reflector, 750 mm focal length and I want to get a Barlow lens to get better observations. I have 2 eyepieces, one 9mm and one 25mm. </p>

<p>My question is:</p>

<blockquote>
  <p>Should I go for a 2x Barlow with the 9 mm eyepiece (167x magnification) or 3x with the 9 mm (250x magnification)? </p>
</blockquote>

<p>I know that a 6 inch can handle about 300x. Is the 3x Barlow too much or is it suitable for what I currently have?</p>

What are you observing? For what do you need such great magnification?

(Asked by: username_0 on 2020-05-25)

I recently bought a 6-inch reflector, 750 mm focal length and I want to get a Barlow lens to get better observations. I have 2 eyepieces, one 9mm and one 25mm.

My question is:

> Should I go for a 2x Barlow with the 9 mm eyepiece (167x magnification) or 3x with the 9 mm (250x magnification)?

I know that a 6 inch can handle about 300x. Is the 3x Barlow too much or is it suitable for what I currently have?
