Useful page , and see what your saying now. . just can't help thinking a 5mm bst would be better value than a Barlow for rare occasions of planet viewing.

Page is bookmarked for future use!

Also. . does the 'no Barlow is best' statement not lead me back to thinking maybe a 5/6/7mm ep may be worthwhile for Saturn viewing? Money better spent on this than a barlow?

I see. . . can only see a 2" panaview? Also seems expensive

Would the basic Barlow not make the bst poorer quality?

I need to work out what's the best xmas present option. . . bst 25mm, a planetary 7mm, a 32mm of some description or maybe a better barlow

Are you suggesting I may be better sticking with what I got and not getting the bst 25mm?

I see. . Good advice. . I was already thinking of getting the bst 25mm, so maybe a planetary 7mm and a good a good Barlow is best?

Possibly a 32 once I've experimented more with the 25

Suppose I'm guilty of trying to rush into all options at once, where I should perhaps experiment more with what I got

The view was good, but was my first view, so I guess going with a bst 5mm May be a good idea, then look for an improved Barlow

My focal length is 900.

The scope is f6.92

Would a specific planetary 5mm be a better choice than going for anther bst?

Oh I see. . I sorta figured with 32, 25, 15. 8 and 4mm eps I'd have a good range and no need for a Barlow. Which I think is sorta what this post suggested, although I think calculations for the high power piece suggests 5mm

I was recommended the Skywatcher Deluxe 2x Barlow. It works well for my eyes. You can, should you wish, just use the lens cell as a 1.5x Barlow?

Lens cell?

craigfoot......your intended 4mm Planetary will be dimmer than a 7mm which would be more suited to your telescope? The 4mm will be pushing the limits. You could Barlow the 15mm to give 7.5mm!

My standard 3.6 ep gave good views of Saturn last year and could clearly see the rings, I'm concerned I won't get the detail with a larger ep too

I have the standard Barlow that came with the scope, but should I get a better one to match the bst eps?

Hi I've just read your very informative piece about ep's which is quite enlightening but the problem is it doesn't cover my telescope my telescope is a skywatcher explorer 130 on a eq2 mount the focal length is 900 mm which equates to a ( f6.92) and your piece doesn't mention that I've just bought some plossal ep's for £80 in a case & I'm now wondering if I've done the right thing the lowest is 7.5 and the highest is 25 mm there are five altogether and I also bought three plossal's for viewing the planets only and they are stunning so what do you suggest I do now I also forgot to mention that I've got a x2 Barlow lens which I don't like using very much so if I get away without using I will thanx for incoming advice :-) Jimmy

I've got the same scope, I have the standard 10 and 25mm eps which came with it and also the skywatcher 3.6mm too.

Recently purchased the bst 8 and 15mm eps. Both give great views.

I'm thinking of investing in a 32mm ep and also a 4mm planetary ep.
