Lens

[dean069]

Hi guys, I’ve got a 10 inch dobsonian and it came with the 10mm and 20mm lens which are not the best 

the scope been in the shed for 2 years and never moved, but I’ve moved house last year and I want to get back into it 

so I’ve got about £150 to buy a few better lens 

any ideas on what to get

BST Starguiders are about £50 each so I'd look at getting three of those. 

I'd suggest the 12mm for sure, 18 or 25 if you want to replace your current 20mm and then one or both of the 5 and 8mm depending on how much cash you've got left to spend. 

There is actually a set of four Starguiders going for £120 in the following classified ad:

And they're referred to as eyepieces, so as to limit confusion if you ask a seller or retailer about suggestions.  They are made up of multiple lenses.

That Dob probably has a 2" focuser, so a nice widest field 2" eyepiece in the 30mm to 40mm range would also be a nice addition somewhere down the road.

Sorry eyepieces ?
