A few years ago i jumped in and bought one of the first lunts available when they were offered for a "special " price. since getting it i have only used it a few times - and that was visual and very brief. I think i have used the lunt only 4 times since having it. well now i think i have used it more in the past two weeks then the whole time i have had it. i am imaging with a DMK41 mono and the dust moates are ruining the potential for the gear. I cleaned the corrector lens on the surface of the objective, the dmk, then i moved onto the BF1200 - OMG i nearly died. at this stage it is far too late to have it sent back to lunt to have it repaired but i cleaned it with the BINTEL corrector lens goop - jungle juice for the optics that stuff. it helped a bit but overall this BF diagonal is stuffed - i will put up with it for now for the transit but i will need to get it fixed. in the meantime i need to learn how to process with the crud i have
