Caldwell 14 Posted February 19, 2012 Share Posted February 19, 2012 I have a bit of an issue going on with ghosting. I used Jupiter and Venus as my targets this evening and my results are as follows 25mm nothing, 18mm, nothing 12mm and 8mm both affected by nasty little dancing faeries. Is that the kind of result you would expect to see or have I bought a dodgy 12mm and 8mm eps'? I honestly can't remember if I had a problem with the baader zoom I had a month or two back or whether I am just getting a little tired of it. I was debating flocking my tube but now there is a suggestion of ep's could be at fault. I will pull my scope apart and flock it if I have to.

Zachariah Posted February 19, 2012 Share Posted February 19, 2012 If some lenses are ok then its odd. What scope do you have. I looked at jupiter tonite and it was not good. Link to comment Share on other sites More sharing options...
182570 Posted February 19, 2012 Share Posted February 19, 2012 much more likely to be atmospherics,try again next clear night you'll find (especially on the planets that the 'seeing' is dependant on the how stable the atmosphere is. Link to comment Share on other sites More sharing options...
Ags Posted February 19, 2012 Share Posted February 19, 2012 I think it is the light bouncing off your eye and back onto the lens. I see it from time to time too with my TMB clones. Link to comment Share on other sites More sharing options...
Caldwell 14 Posted February 19, 2012 Author Share Posted February 19, 2012 No honestly its none of those things. this has been going on for a while. The light dances about over the whole field of view in a random fashion only when viewing really bright objects, the targets are always very sharp and well defined, stars pinpoint, nothing blurred (thats the TAL 100RS for you) Often it takes a feww seconds for the light dance to begin with and appears to get worse fro a few seconds before appearring and reappearing (a bit like aurora) Link to comment Share on other sites More sharing options...

Mr Q Posted February 19, 2012 Share Posted February 19, 2012 Sounds to me like an eye phenomena? Ghost images can be caused by lens problems in the EP(s) or reflections off your eye. Because the high power EPs seem to be only effected, I'd guess the shorter eye relief of these may be causing eye reflections? Link to comment Share on other sites More sharing options...
Tribal-Wolf Posted February 19, 2012 Share Posted February 19, 2012 I got a good view of Jupiter tonight and a shooting star flew passed my fov as I was star hopping. I had the clouds roll over too. Is all viewing problematic? Could it be vibes? Link to comment Share on other sites More sharing options...
182570 Posted February 19, 2012 Share Posted February 19, 2012 I've got the same scope as your's ,not had that problem,sometimes the atmosphere causes probs but other than that i'll leave it to the experts to decipher Link to comment Share on other sites More sharing options...
John Posted February 19, 2012 Share Posted February 19, 2012 Have you tried twisting up (or down) the eye cups and using the eyepieces with them in a different position. I think the BST Explorers have twist up eye cups Does the problem get better or worse when the bright object is central, off centre, on the edge or just out of, the field of view ? Just some things to try. Link to comment Share on other sites More sharing options...
Caldwell 14 Posted February 20, 2012 Author Share Posted February 20, 2012 The position of the object makes no diiference at all I'll try the eye cup thing next. Link to comment Share on other sites More sharing options...
Ags Posted February 20, 2012 Share Posted February 20, 2012 I'm certain it is the light bouncing back off your eyeball... :-) It drives me mad. Link to comment Share on other sites More sharing options...

nightfisher Posted February 20, 2012 Share Posted February 20, 2012 I have the same scope as you and similar eyepiece`s, cant say i have had this problem, good luck getting to grips with it Link to comment Share on other sites More sharing options...
MjrTom Posted February 20, 2012 Share Posted February 20, 2012 I'm certain it is the light bouncing back off your eyeball... :-) It drives me mad.I would say its this.I get it all the time when viewing bright objects.Eye placement is usually key to alleviating it.Also try cupping your hand around the eyepiece just in case it is extraneous light from a nearby street light or house.

Caldwell 14 Posted February 22, 2012 Author Share Posted February 22, 2012 Solved, I just twisted down the eyecups to half what they were, simples.... Link to comment Share on other sites More sharing options...
