... what's wrong with using batteries...!!!!

They are too heavy to carry [for me at least].  I can't even lift them!!!!

True Delphine - I'd overlooked that. I would of course be more than happy to assist you carry or taking your batteries down for you if needed..

I just think mains cables drapped everywhere would be a nightmare. The only way I could see it working would be if there was a designated area for the 'mains users' I have enough problems not tripping over the tent ropes (& have done so on quite a few occasions) - the thought of 50m extension leads & damp wet grass scares me. Saying that though it would be useful to have mains during the day for battery charging etc.

Thks,  John

I was thinking of the battery charging bit, as my battery ran out last time. Mick lent me his.

But
Laptop power supply = about 2 amp
Mount  ------"------- = about 2 amp
Plug top fuse            = 13 amp
Plus you would also need it to be a long heavy duty lead.
Only 3 people could use it   :(
Pity, it was a nice idea

I've got some rigger boots and rubber gloves, i'm sure theres an 11kv feed next to the field, quick tap off of the transformer :afro:
and it will be free.

The laptop, doing long exposures for around 2 hours hosting a guiding cable, CCD camera & guider camera must take a lot more power, than just viewing thru the telescope.
Then if you have a bad night & are slewing here & there,  the power will not last long especially if it is cold!!!!!

I think mains leads trailing around a dark field is an accident waiting to happen - people hurting themselves or kit getting damaged.  However, a "recharging station" for batteries would make sense.

Many thanks for the offer to carry my batteries John - much appreciated.  I haven't actually bought any batteries yet as I have been practising with my telescope near the back door of my house.  I agree with the concerns about mains electricity at the DSC.  The charging station sounds like a good idea to me

Cheers

I will have a chat with Jeff and we will talk to the owner about something, maybe in the ladies loo, for charging batteries.
