John Posted August 3, 2015 Share Posted August 3, 2015 Not sure a 5x barlow would be much use to you really - the magnification would be huge even if used with a 25mm eyepiece. 3x and above barlows are usually used for imaging.What eyepieces do you currently have ?Are you looking for a 1.25" or a 2" barlow lens ?Sorry for the Q's but I want to come up with decent and usable suggestions Link to comment Share on other sites More sharing options...
LukeSkywatcher Posted August 3, 2015 Share Posted August 3, 2015 I have to agree with John. Ive only heard of imagers using 3x or 5x barlows. For purely visual use............a 2x will be enough. Link to comment Share on other sites More sharing options...

LukeSkywatcher Posted August 3, 2015 Share Posted August 3, 2015 I have 25mm 15mm 8mm all bst and a 10mm and a 12mm from my old skywatcher scope i hadThe 25,15 and 8mm is good enough. I really dont see a need for a barlow. Once you have a high,medium and low EP............that really is all about you need. Link to comment Share on other sites More sharing options...
paul mc c Posted August 3, 2015 Share Posted August 3, 2015 With your eyepieces a barlow wont really benefit you much,a longer fl eyepiece like a 32mm wide field eyepiece would be great in your scope. Link to comment Share on other sites More sharing options...

Charic Posted August 3, 2015 Share Posted August 3, 2015 ......using Starguider EDs, I use Skywatcher`s 2x Deluxe Barlow. I can remove the Barlow tube and just use the lens cell fitted directly to the EP to give a Barlow factor of approx 1.6x. This suits my needs just fine, but I use a much smaller and slower scope to yours!Can I also ask, how do you deal with any coma on your f/4.5 using the BST's?

John Posted August 3, 2015 Share Posted August 3, 2015 I agree with the other posters. What you are missing is a low power eyepiece. Link to comment Share on other sites More sharing options...
