    Levesdome, Encoders and Shutter Motors

    Hi - I used the 8 ppr Bourns encoder with LesveDome and a windscreen wiper motor and my old style 2.2 Dome will track an object I am imaging pretty well which is all I wanted - the problem was not attaching a sprocket but building the dome drive system that took many prototypes as I like to call them {failed ideas others might say ) but you seem to have done this so the rest should be relatively easy - Tony.

    Revelation 25x100 - collimation

    Hi - if its any help, I have collimated several smaller pairs of binoculars with success and can recommend using a medium magnitude star- only adjust one screw at a time and note down exactly what you did so this can always be reversed - with a star, small separations in the images of the binoculars are very obvious and making small adjustments can get you closer and closer to perfection - the results on terrestrial viewing were dramatic - Tony

    DIY Dome drive & interface

    Hi- I've used the LesveDome software and a windscreen wiper motor and the Vellerman 8055N board-this interfaces well with ASCOM- - took a while but works well- the dome rotation system ie the mechanics is the hard bit I feel - Tony.

    Pillars in M16

    Great monochrome -Tony
  5. Thanks - I agree - I like the idea that WD40 and an angle grinder will solve many of life's more difficult problems- Tony.

    RC 8" and focal reducer

    With RCTs reducers can flatten the field and provide a useful field of view and are widely used - an AP 0.67 is a good choice-Tony

    RC 8" and focal reducer

    Hi - I used an AP 0.67 on my 8inch and generally was OK but you have to get the spacing right or you do get star distortion at the edge of the field - tilt can also be a problem - if you try go for too much focal length reduction these problems will increase immensly- I use a Riccardi reducer on my 12 inch RCT and spacing has been a pain - finally worked out best distance but still have a little tilt - spent 3 months experimenting with reducer to CCD distance before I was happy with peripheral stars and bought a load of spacers so not without some tricky issues- Tony.

    NGC 6888 Crescent in HOO

    Great image - punchy with small stars and good detail- Tony
  9. My wife is threatening to move- with me I should quickly add!- but I wonder if I will be able to unbolt my observatory from its concrete base? - The bolts have started to look a bit rusty and stubborn - a bit like me really !-We have already debated that the new house owners could have a discrete Jacuzzi or green house on the concrete octagon when vacated (no sun though as it is all hedged in now!) - still I can see the truck with the fiberglass bits heading off to some new dark site hopefully 1000 metres up - unlikely in Eastbourne! Still my point survives all these considerations, it will go with us!-Tony.

    Messier 31

    Hi - great image that does justice to a near neighbour- Tony.

    8x44 Bins ?

    Hi - I have a pair of Audubon 8.5 x44 - was worried about reports of misalignment and mine were a bit out but they are beautifully made so aligning with a star was really quite easy and improved them a lot -I love the bright big field views- recommended - Tony.

    Essential Mod for Pulsar Dome

    Thanks for your expert advice guys but I have to think of the neighbours and and the inclusion in the observatory of a light sub machine gun would upset them a little- no I favour going the the 2.7m Pulsar pond route - I can be out there imaging M51 not alone but with the gold fish swimming round and round and the waves lapping at my sandals-Tony.

    Essential Mod for Pulsar Dome

    Maybe this is the way forward for me but would need a good bilge pump- go down 1 metre and have a new 2.7m Pulsar Dome -not sure whose field I could dump the water on though? - perhaps the guy downhill at the bottom of my garden - Tony

    Hi ALL

    Hi and welcome - Tony.

    Essential Mod for Pulsar Dome

    Well- Domes are Domes and people over 6 ft don't fit well in small Domes, so bend over on the way in and out - I blame myself ( and sometimes the neighbours!)- I have thought of a bigger dome and digging down into the Sussex chalk to avoid the height that would surely distress next door, but water drainage and flooding would prevent this in the UK and then I would need not only to bend down but use a Kayak!- Tony.
