Re: Astelco NTM-500

Hi Gary,

My first impression of the NTM-500 - it reminds me of a mount I saw in South Africa proof and experimental range for tracking high speed projectile :)

Really wander if it need to slew so fast for use by astronomer :)

Re: Dehumidifier

I use Keter plastic cupboard with 5W light bulb like in the old army camp of keeping optical equipment. The cupboard is available from NTUC @ Serangoon Nex for about $100. I use plastic adhesive tape to cover the gaps. Humidity is kept at about RH 60%. http://i.pbase.com/g4/08/993808/2/141594483.zOQ...

Re: Help Needed - To adapt Vixen SXD for local altitude

Hi Orly,

Thanks for your reply. I already have a half pier installed. There seems to be a mechanical stop that is preventing the latitude setting going below 23 Deg. Do you have a SXD?
