If you're in it for long term, and will likely get deeper into imaging, especially planets, a Televue powermate will be a better investment due to its optical correction, the 2.5x one will do. Its expensive but it's edge correction and sharpness is very good. You can get good results with a standard Barlow, I've used a few, the Celestron Omni is okay as is a Meade telenegative. At the beginning I made the mistake of buying a basic 5x Barlow and never used it after testing it.

I checked the  Televue one, I think in the future I will get it but not now, for now I think I will get the Celestron one  thankyou for the recommendation  and I will get the 2x barlow one  

My eyepiece 7-21mm zoom just came in  

I am so excited to try it out later

I hope the weather stays like this, no clouds

Thanks again everyone for helping me 😊

And I will get the barlow 2x (1.25inch) 😊

I actually prefer a 1.25” barlow due to the 2” eyepieces I have are long focal length (30mm) for example. Using a barlow with this is pointless as I have that magnification covered by other eyepieces (as will you if you buy the 7-21mm zoom. Also again a 28mm-30mm eyepiece already has a considerable eye relief (the distance from the eyepiece lens to your eye) and this could become uncomfortable to use if you were to double it with a 2x barlow. A barlow increases the eye relief as well as magnification.

Oh okay, 

I am going to order the eyepiece first, 7-21mm zoom today

Just make sure it comes with an adapter for 1.25 inch and you are good to go.  On a side note, barlows are worth spending a little extra money on.  Eyepieces will come and go, but a good Barlow is forever. 

Oh okay that’s good to know! Thankyou so much! 😊

Thankyou!!

No you would need a 2” barlow to use a 2” eyepiece but you can use a 2” barlow with both the 2” and 1.25” eyepieces with the addition of a 2”-1.25” adapter. You will discover the sky seeing conditions by observing a target and gradually increasing the magnification until you suddenly lose the sharpness of your image. That’s a good indicator of the seeing conditions.

So it’s better to get a 2inch barlow, because you can use it for both 🤔

oh okay 😃

thankyou!

Hi everyone first of all thankyou for replaying

So I am not going to buy a 5x barlow 😃

I am going to get the eyepiece I mention before, the Svbony 7-21mm and a 2x barlow. 

I have another questions: 

- Can I use a 1.25inch barlow on a 2inch eyepiece? 
- How do you know what your sky limit is? 
 

thankyou again @Mike Q @bosun21 @Cosmic Geoff  @Philip R 😃

hello, I am new here and nee to this hobby 😁A 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 😁

thankyou!
