Thanks all I have just started using the Lunt again after several months building an observatory extension and re decorating the inside of the house (promised her indoors!) so was very lucky to catch this on my 1st day.
Thanks for the generous comments, I'd not used the TV 2.5 powermate on the Lunt before and so will be using it whenever the seeing is good and something interesting appears. I've ordered another TV T adaptor so I don't have to keep taking it from the 5x on the Newt, and increasing the cmos dust cleaning.
