Good morning all,
I have an Orion 130mm reflector with a 10mm and 25mm eyepiece.
My mum's day pressie was a voucher for the Bintel shop and I've been perusing their website and was wondering if a barlow lens would be a good idea. (I had to do a google search to find out exactly what they're for).
How much difference will it make to viewing planets and dso's, will it make much difference or just a little bit.
I'm eyeing off a book on messier objects as well but I can't afford both, so I want to make the right decision.
I hope this isn't too daft a question.
Thanks in advance,
Molly.
