good barlow

[kipstar 10]

Need a new barlow for my scope i think i started a post months and months again im on my phone and cant find old post so fort i would ask again sorry does anyone now what sort of barlow would be best for my scope its my birthday so other people are paying hahaha my scope is a

Revelation 16" f/4.5 M-CRF Truss Dobsonian if made my own stand forit it doesnt move a mm without me pushing it so very stable i did want a x5 powermate but not sure now if anyone can help would be great thank you

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

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.

The 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.

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.

......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?

i have a modded phillips 900nc camera and started to computerize my scope for tracking

[LukeSkywatcher 15,630]

Best EP i have ever owned.............32mm GSO.

[John 34,446]

I agree with the other posters. What you are missing is a low power eyepiece.

my 30mm vixen npl is a fantastic widefield  eyepiece for my f5 130p only £45 aswell bargain

[kipstar 10]

Sorry i do have a 32mm eyepice as well it come with the scope 2ich one so it doesnt get used alot and about the coma i only really look at and take pics of the planets and moon no tracking at the moment so pics of the star clusters and nebula are out of reach haha sorry about the spelling

The Baader 2.5x barlow is a very neat small package.

Use mine a lot.
