  1. Yes Mike - a dilemma:rolleyes: A decade ago we disposed of our fibreglass moulds for 3m domes when the cost of GRP rocketed. There are sure to be unused domes about in fair condition - just need to find them if there's no time to build one :D

    If I were doing-it-again I'd make an octagonal dome like wpo - Ron Johnson's astro-dome that uses simple rectangular ply panels [curved into partial cylinders] + 4 triangular corner panels - you'd never know the dome wasn't spherical but now we're into aesthetics:D

  2. Hi - most hereabouts seem to favour RoR but this could be stripped to the basics with windproof screen and storage of fixed scope and maps + EPs with means to keep condensation at bay. I snapped a few items in the garden centre lunchtime that could form the basis of simple observing station as sketch below:rolleyes: Hope it's of interest.

  3. Very nice image :D- wish my skies permitted such exposures:mad:

    The streak looks to me like an optical diffraction effect as if there's partial obstruction by a straight edge over the scope or within the camera - but why not on all the brighter stars in pic can't say:rolleyes:

  4. Hi - my first DSO image thread on SGL :p - Bear's Paw galaxy NGC 2537 in Lynx via my classic Meade 30cm LX200 @ f/3.7 + StarlightXpress OSC Lodestar-C cam in 4m exp [4x1m subs] -gxy N2537A to east in pic.

    I'm not a perfectionist and these are my typical exposures so I can capture as many DSOs in an evening :D Hope you find my approach acceptable :)

  5. Hi - just spied the welcome page so hello. I'm retired with a long interest in astro. Wouldn't survive without my little DIY observatory. Don't use EPs much nowadays due to poor eyes but my Lodestar-C cam on classic Meade LX200 effectively ignores the dire light pollution so great fun!

  6. I should learn how to process noise out with LRGB.. but here's a native resolution crop.
    Great close-up Nick :) Here's my quick 'n dirty 60sec worth on Bear's Paw=NGC 2537 from tonight on zenith - an amazingly well titled object. There's another small gxy NGC 2537A to east :(

    ps: I'm new to SGL - is it ok to post images on another's thread?

  7. It's getting there :p - another 20 subs or so to go before I have to turn in so I can get up for work tomorrow.... :mad:
    I feel your pain - I'm midway between Gatwick and Heathrow but not directly under either flightpath - as my skies are bright orange - new full cut-off street-lights away from main road make no difference :(

    I resort to fast optics [12" f/3.7] and brief exposures [1m subs] for my deepsky stuff with moderate success getting down to mag 17/18 fairly easily - last night got tiny and faint Hickson 50 gxy cluster @ 2BLY range but whatever turns you on :)

  8. Hi Ken - are you finally taking the plunge ? I've built 6 domes over the decades [two for myself] and wouldn't do it any other way. Can't see the point of going to all that trouble and effectively "standing outside" a RoR observatory.. I can do that on the patio anytime. :)

    However I'm told by the experts here RoRs are 'easier'? but anyway good luck with your project:rolleyes:

  9. Thanks Gina - must admit I'm not as 'exposed' as you to the surrounding [Devon] landscape - mine's hidden in my garden:)

    You've certainly got a massive structure there - even the concrete founds made me wince. You're lucky to have no dew or cold winds thereabouts - scrolling down the your many pages it becomes a nice 'flick movie'. Well done :)

  10. I too use a Lodestar - on my piggybacked ETX-70 with PHD freeware to autoguide my classic Meade LX200 and it works fine.:p The Lodestar is very sensitive - I use PHD at 1.5s exp with maybe 1/2 dozen suitable guide-stars on view. I set PHD to track in RA only and 'Enable Graph' to watch tracking progress.:)

    ps: Also use SX Lodestar-C OSC cam as prime imager and I'm loving it :(

  11. It is tricky to find - immediately above bright zeta Tau [lower Bull's horn] are two faint stars forming a triangle with zeta - follow a line through these two faint stars westward

    for 2/3rd their separation and slightly downwards for M1 - good luck

    :)

    If you have an equatorial mount then center M42 Orion Neb using low power EP then release Dec lock and sweep scope vertically upwards - M1 and M42 have virtually the same RA :icon_scratch:

    My M1 pic via little ETX-70 e-finder from last week below:rolleyes:

  12. Hi - my first post here:hello2: I'm deep in London LP but do DSOs in brief exposures via my 12" SCT at f/3.7 + SX Lodestar-C in typical exp 1m -5m [in 1m subs] to make the most of few clear nights and to get as many different targets :icon_scratch: Anyone do this sort of imaging - for me a substitute for eyeballing:rolleyes:
