hello, I am new here and nee to this hobby πA few weeks ago I bought my first scope. the skywatcher explorer 150pds. And now I am thinking to buy a barlow lens/eyepiece for visual and later on for astrophotography.
I saw in a youtube video about how you can calculate the max magnification and stuff:
it's a 6inch, which mean 6 x 50=300x
so my max magnification is 300x
telescope fc is 750mm and the eyepiece I have is a 28mm
so 750/28= 26,78....
so it is okay to get the 5x barlow? because 26,78.. x 5 = 133,9x ? (if I use the 28mm eyepiece)
I was thinking to get an another eyepiece (this one: https://www.amazon.nl/gp/product/B07Z64NK65/ref=sw_img_1?smid=A3ICDZYF91YIY1&th=1 ) + 2x barlow lens
OR
this one ( SVBONY SV170 1.25" Eyepiece Zoom Eyepiece FMC Green Film Zooeye for Telescope (10-30mm) https://amzn.eu/d/5pJSPrj )
- Is this a good eyepiece to get? and can I use this eyepiece on my telescope? Which one do you recommend?
- Does the size of the eyepiece influence the visual and for astrophotography?
- Do you guys have any advice what I should get?
I am really looking for to get in deeper in this hobby
Sorry for my poor english language, english is not my first language π
thankyou!
