BST EYEPIECE

[kipstar]

hello whats the diffrence in<h4>

[John]

I think you are going to need to give us a bit more to go on !

[kipstar]

sorry the 8mm BST explorer dual ed and the 8mm 58 degree BST wide angle

[kipstar]

i dont know what happend in the first post haha

[Naemeth]

They are different designs. The former has a better reputation than the latter. The 8mm BST Explorer EDs are now called Starguider EDs, there is no difference, just a name change.

No problem

I think Jonathan (Naemeth) sums it up nicely.

The BST Explorer/StarGuider has a AFoV of 60 degrees, not that you would notice the difference, and I think ergonomically they are better designed. With the 8mm StarGuider you need to use it with the twist-up eyecup fully extended, as there is a tendency for this particular focal length to black-out. This does not take away from the superb nature of this eyepiece, which is a very comfortable one to use in any telescope.

The BST wide angle are just for planetary observing, I find them very good

for viewing the moon, also great value for money, the StarGuider are for general

observation, both are good quality for the price, and the planetary are cheaper.

I have a few bst's , couldn't give you all the technical bumf like my more learned sgl'ers but they are a far far better ep than stock , cheap too

[damnut]

The BST's are excellent for the cost, I would not limit them to planetary, good all rounders.

For the OP, if you search on here you will find very favourable comments on the Starguiders, I have 4 of them and am very happy with all of them, especially the 18mm.

+1 for the BST Explorers (Starguider) eyepieces. I found them to be great in the sizes 5mm, 8mm, 12mm, 15mm. In my f/5 scope the 18mm and 25mm were a little soft around the edge but otherwise good.

Fair comment in my opinion.

Just bought 3 BST's of Alan at skies the limit to give them a whirl, everyone raves about them so I thought it was time to try them out. I'm a sucker for vixen NPL's though so it will be interesting to see the comparison.

Hi Helite, often best used with the eyecups twisted up to their full extent.

Another vote for the BST's. Saturn looked fantastic through the 8mm the other night in my 200p Dob.
