  1. You have almost an identical setup to me.  I hear good things about the ES 24mm 68.  I have an Astronomik UHC but not really used it yet.  I believe the veil nebula is in Cygnus which is easily visible from my back garden.  I will try and use it this week and let you know.  I certainly can't see it with the naked eye or without filter at Bottle 6.


    I owned the baader mkiv zoom but didn't like it.  Too narrow fov for me (some people are ok with that)


    Baader classic orthos are very good for planetary work.  My next EP will almost certainly be a low power wide fov.  68 or 82.

    There's another simple trick you might try. Deep sky observers will often use averted vision to detect faint detail. This requires that the light sensitive rods, which are situated around the periphery of the retina, be allowed to naturally scan the object on view. Rods too play a major part in detecting subtle planetary detail, and so if you're able to relax and let your eye naturally scan the tiny planetary disk, the rods can pick up on some very subtle detail. Staring directly at the planet can actually be counter productive. So try looking very slightly to one side of the planet while still concentrating on its disk to see if it helps. Don't force it, scanning the disk naturally is the key!

    I used this technique to good effect with the M31 Andromeda galaxy.

  3. Hi All

    I have been upgrading my ep collection and currently have a BST 8,12 and Vixen NPL 30mm

    I just purchased a BST 3.2mm because I'm struggling to find the BST 5mm.

    Do you think this is too much for this scope?  (Haven't received it yet by the way)

    3.2mm would give 203x in this scopes FL of 650mm.

    It's a big jump from the next ep down of 8mm (81x)

    Or does it depend on good seeing conditions?


    Edit: when I say 'too much' I mean for planetary observing.

  4. Hi.


    Can anyone recommend a 25 or 30mm EP to locate targets in my scope?  I was initially looking at BST 25mm but reviews have put me off. 

    Was thinking of a Vixen NPL 30mm which would give a mag of 21x in my scope.

    Also, are the Vixen ep's fine in my Focal ratio of F5 (i know some ep's struggle)

    These filters only improve the views of nebula. For galaxies, find the darkest skies you can.

    With a 130mm I would go for the full UHC rather than the UHC-E. I use "full" O-III and UHC filters with 100mm apertures to good effect.

    Looks like @Stu agrees with me 😀


    Thanks both.  Think i am struggling to understand (being a newb) the difference between O-III and UHC.  Also wondering if the Astronomik UHC and TV Bandmate are the same thing albeit higher premium for TV name etc?

    I have not seen any Nebula.  Only galaxy I have seen is Andromeda, which looked cool, but LP was probably affecting my view so the filter(s) may help with this?

  6. Apologies to hijack the thread but I have also been interested in filters.  The Astronomik UHC or cheaper UHC-E or the TV one (made by Astronomik).

    Was considering the UHC-E which according to Astronomik is better suited for smaller scopes up to 127mm.   Mine is 130mm so not sure if that would make a difference :)

    A lot have people have been saying get the best quality ones as numerous cheaper ones can end up to the same cost as Astronomik/Lumicon ones?

    I'm interested in nebula and galaxies (not sure if these filters have any effect on Galaxies?)

    Edit: Forgot to mention this is purely for visual observing.  Not imaging.

  7. Thanks.  I have been looking at doing this.  As the weather has been so poor.  Light shroud, flocking the tube etc with the flocking material sold by Flo.  And the PTFE tape trick.
