Barlow - worth it?

[Tabciogaraj]

worth buy a Barlow lens? How is that so? no big price and good.

Greetings!

A barlow doubles the flexibility of all your eyepieces, it doubles the "zoom" of the eyepiece. So if you have a 2x Barlow and add it to a 16mm eyepiece, the eyepiece becomes a 8mm one. It's a must have in my eyes (lol pun). I am not very good with brands since I'm new but there are a ton of threads on this and the veterans should probably be able to help you with specifics.

I ordered a kit with decent Plössls and a Barlow, but I might go for a high quality 2 inch barlow at some point.

I have the stock 10 & 25 and x2 barlow that came with the scope. I purchased a 7.5mm one and now i must say i very rarely use the barlow.

[Tabciogaraj]

I have a 25mm,10mm and SW UWA 6mm, Barlow is good for this?

[Matt Scunthorpe]

Personally i wouldn't get one. You have a good range there anyway. Barlowing the 25 would give you 12.5, not far off the 10 you already have, and the 10 would become a 5, again, you already have a 6.

Id save the money or get an EP to plug the gap between the 25 and 10.

Without with barlow

25mm - > 12,5mm

10mm - > 5mm

6mm - > 3mm

Since 12,5mm is pretty close to 10mm and 5mm is pretty close to 6mm I'd say you already have a pretty good range as it is without one.

But if you want too zoom your 6mm down to 3mm its very good.

Hope this helps a bit

I would say stick to purchasing ep's, I find that I prefer not to use a Barlow, even though I have a pretty good one, when viewing I prefer to increase the mag more gradually. Doubling it sometimes you just lose the object altogether.

3mm = give a good picture on Jupiter? i no have Go-To.

[VigdisVZ]

It depends, what scope do you have? If you zoom up too much with an already powerful scope, you will get too much atmospheric distortion and also risk losing track of the the planet if it goes outside of view. Higher magnification isn't always better.

Here you can enter your paramters and get a rough idea of what you're going to get http://www.12dstring.me.uk/fov.htm .

[Matt Scunthorpe]

I would say 3mm is too strong. Jupiter would race across the field of view, id imagine it would be a fairly blurry image also.

I double what Robin has said above, i would stick to EP rather than barlows. I tend not too use mine.

[pvaz]

With your current EPs I would skip the barlow and get another EP around 13mm.

With no Barlow 2x -

With Barlow 2x

With barlow 2x picture will be a strong?

[Stargazer33]

Barlows are handy for imaging planets etc with a web cam, but I must admit to not using mine much any more for visual observing since I bought my new scope. I tend to mainly use the 18mm Xcel-LX and my 10mm Meade Plossl.

Camera to the barlow ? No eyepiece?

[kenny k]

Not sure with compact camera but I use x2 barlow with my dslr& t ring adapter with 1.25 barrel.

Great for lunar ap.

summing it - worth it? my opinion is not a little favor for yes.

You dont really need one with the EP's that you already have. Save your money. Buy a 13-15mm EP instead.

[VigdisVZ]

It's nice to have one, but you really don't need one at this point as Paul said, so you could probably save the money.

[LukeSkywatcher]

Instead of buying a 2x barlow...............buy a 15mm EP

This will give you a collection of: 25mm,15mm,10mm,6mm.

Thats pretty much all you need.
