Hi Guys New member, ancient ATMer. I have joined to directly access Pulsar dome owners' fund of information. I am building a raised platform 8' off the ground to provide a much bigger sky. Trees and hedges surround and interrupt our dark rural property. Our modest 1.5 story home is on the southern border of our large garden. Fortunately neighbours with security lights at a hundred yards south and SW are safely hidden by the house. Increasing age demands shelter from the almost constant wind. My two main OTAs are now much too heavy for easy lifting: I am using a chain hoist and nested stepladders! I have a 10" f/8 reflector with premium optics and a 7" f/12 R35 iStar refractor. [Presently folded.] Both ATM builds. My almost completed, massive DIY GEM has 2" shafts and lots of heavy aluminium. ie. Immovable! It is running AWR IH2/ASCOM drives to 11" and 8" Beacon hill wormwheels. The images show my mounting on a temporary test stand. Now the real reason for my unscheduled interruption: [Much as I like talking about myself.] I am torn between a DIY all aluminium, rotating "dome" of the cylindrical roof variety or buying a Pulsar 2.7m. dome only kit. Making a hemispherical dome is a long term exercise in geometrical and sealing frustration IMHO. The off-the-shelf Pulsar 2.7 is rather cramped for my 2 meter long Newtonian even when the dome is mounted on a much larger "box". Does any recent Pulsar 2.7m dome purchaser have the minimum internal dimensions between opposing quadrant ribs? I understand the 2.7m is actually 2.6 from Pulsar's own drawings but that may be external. With so little clearance available I really need an accurate figure. Thank you for your patience if you have reached this far. Regards, Rusted
Hello Just a quick question about the weight distribution on a eq6. I have a SW 150pds and I have a situation where I am able to balance the scope using 1 or 2 weights. I noticed while setting up I can place one weight low on the weight bar and balance the scope or I can use two weights but move them both up close to the main bulkhead. Am I correct in thinking that 2 weights closer to the centre of gravity or higher up the pole is better than 1 weight? Or am I adding unnecessary weight to the mount. Thanks for your advice. Gerry
