Barlow lens

[JonnyK]

Hi, im just wondering if it is worth investing in a barlow for my celestron 130 (astromaster)?It came with a 10mm eyepiece and I have some cheap ones kicking around from another scope (6mm,12mm and 20mm) Would it be wise investment or a waste of money?

not so sure that it would be of much use to be honest
