  1. No disrepect inteneded, but whenever someone tells me it's simple I never seem to get it right. I have used the loader to load an MPC file and a KML file and as far as I see I have done this and there is Nothing showing on the charts and I know where Lovejoy is. Any ideas apart from get someone that knows what his doing?

  2. I have more than a few laptops and many software programs on them but on my LX I have tended to use the Meade program. This however as many times as I have tried never seems to have comet data uploaded to it. I can connect in the obsey to the internet as well but I must do something wrong.

    My main use of the laptop is for startmaps and goto combined and whilst the computer is not new it is a very high spec Dell model made for professional use with the RS 232 port.

    I was thinking of giving Carte du Ciel a try which I have loaded, can someone either take the time to tell me how to up load data or is there a link showing how for software dimwits like me and I do mean dim.

  3. Once I settle into my new collection and I am happy, I am going to make a thread and detail what I have and why I have it. It will be a cathartic way of justifying why I have a few hundred quid (previously a few thousand) of glass. 

    Just need some clear skies, oh wait erm  :confused:

    Steve,

    Then we can tell you how much better 'A' is than 'B' and then your back to phase 1 :grin: .

  4. Tinker,

    It  was always a tug of war between the TV Panoptic and the 40mm XW for wide field, in the end I couldn't get one either and that was 3 years back, I guess the other 3.5mm is just a bit too short for you. I always wish they had made a few more in the range especially at the short end of things. Great eyepieces and as John always say's, what would they have done if they set out to make a range of astonomical eyepieces .

  5. I got rid of my Explore Scientific 100 degree EPs, I like the Televues better in my Dobs. I tend to use the 10mm Ethos and Paracorr II most of the time. The cases were made by Ron Burrows at Wood Wonders in the US http://www.wood-wonders.com/

    A stunning collection you have there, I have or have had most of the TeleVues but what is that liitle huddle in the centre of shot, not Zeiss and Supermono's is it?

  6. I could probably have put this to bed sooner - sorry for being late to the discussion. Here is what Vixen Japan told me when I asked them about this some time ago:

    "Once a wrong field of view specification was indicated on the #3727 by mistake and it was corrected to a 65 degree FOV later."

    So, just a typo on the eyepiece. Quite an important typo in many people's view I'm sure...

    If this is the case it will no doubt be exactly the same as my 41mm 68 degree Panoptic which was what I thought all along. I am not just saying this because I have mainly Tele-Vue but I just can't see that they would be outdone with the reputation they have as they always seem to go that extra one, you could say they go to 11.

  7. This is something that cropped up before over a year ago and I am not sure we ever got to the bottom of the question. I have a Televue 41mm and that has a 68 degree FOV, now TV being who they are have always pushed the limit of the envelope. Myself I find it hard to accept that a company albeit a very good one can out Tele-vue Tele-vue, with 1 more millimeter and 4 more degrees, without vignette issues.

    The 41mm in fact show a mild vignette when used in my LX 12 inch scope with a diagonal, the one it was bought for. The limit of what can be seen as you probably know is governed by the size of the field stop of the eyepiece, this must be within a very tiny amount identical on both eyepieces in order to fit the telescopes. If the Vixen is 72 degrees and 42mm I struggle to understand how they do it. I am not saying this is not the case but personally I do not believe it.

    I have even considered buying one to see for myself.

    If there are like eyepieces (65) from your supplier and you ordered  72 degrees based on a picture then I for one would not be happy with what you have received, my advice is send it back and make sure they pay for the postage, it's their mistake.

  8. Taliking about the rare BGO's I got the 6mm 7mm & 9mm without much fuss but I have never seen a 12.5mm at all. I got the Hutech which is fine for me, that too seems optically pretty spot on.

    I have the Kasai in at number 18mm and that is very good too, I am not sure but I wonder if these are all the same just dressed differently. 

    Anyway Stu a very nice set of eyepieces just to get back on thread.

  9. The T4 range look lovely, I had the 12mm and though it is a very good eyepiece and only got evicted from the case by a Delos, I did find it a little difficult with eye placement. The Delos is easier to use but this could of course be different for other people.

    That 30mm Pentax is a size, almost the same size as the 41mm Panoptic and I am looking at mine now.
