  1. I'm sure a lot of them are still around.  I was simply stating that the use of a cheap ASDA camera for luna / planetary imaging isn't new.  Infact, given the constant development of CMOS sensors, a lot of the cheap cameras could be used, assuming you can adapt them to take a 1 1/4" adaptor.

    Hopefully Makc most are 'still around' but absent from SGL - my guess is ~18 mths is a typical active period for most posters unless you know otherwise:-)

  2. Thank you all.

    My supernova search project was starting in 2014 - own software creating, roll-off roof observatory building. Systematic searching since April 25, 2014.

    Some statistics:

    12285 images for the first discovery

    18418 images for the second discovery

    1606 images for the third discovery

    My software sets a different exposure parameters (time, stacking) depends on weather conditions, moon phases and distance to galaxy (radial velocity/redshift) etc, so I never checked SNR for this exposure conditions.

    Thanks Jarek - hope those big numbers don't put off anyone trying for SN hereabouts :-)

  3. Hi Ajedi - my UK astro friends Tom Boles, Mark Armstrong and Ron Arbour have been SN hunting for decades with hundreds of SN discoveries credited to them. Their technique is to compare their own previous gx images with their new pic for new 'stars' then check the SN, asteroids and variable star sites to be sure - false alarms demote you!

    Unfortunately it can in theory take many 100s of gx images before a discovery. I discovered mine 'much too early' so the chance of another is remote at my relatively low level of gx imaging but the chase is irrestible ! I'm connected to the internet at the scope and run Wikisky or Digital sky survey for a gx search when SH hunting and directly compare my gx pic to the digital pro atlas. Results 95% certain if clear of the bright gx core. You need to gen up on SN discovery registration via Google. Hope that helps.

  4. Hi

    Just edit wikipedia when you know the information  in it is wrong.

    It's not difficult, and with every entry comes a discussion page where you can explain the changes you made.

    Trouble is - who is the expert ? Wiki were daft to allow anyone to edit their text as it dilutes further any reality.

    Back to topic - yes a great moon dog but not as quoted by "low mist" but by ice crystals at high altitude even if seen low in apparent sky. The phenomena is identical to that seen quite frequently caused by the sun but obviously much fainter under moonlight. I think if I recall that dogs are restricted to below ~40deg altitude but the right site will define:-)

  5. Strange combo tonight after dusk forced by rapid complete cloudcover arriving from north.   Did M57 [below] then M56 but lost in cloud on 2nd 10s loop!  Sky still clear low in SSW so rapid goto Pluto [below] but again 2nd 10s loop lost in cloud so very lucky!  Used Megastar for field then NASA Horizons to ID Pluto in rich Sgr starfield.  Pics posted direct from obsy ;-)

  6. Extremely brief session after ever earlier autumn dusk - cloud rushed in from the north to cover the sky.  Got a few test snaps of M57 then just a single shot of Pluto field @ 15deg alt in SSW as here direct from obsy.  Next brief exposure cloud bound!  Pluto fov via Megastar then NASA Horizons for ID @ m14.7.

  7. Just a follow up. I found that this mod has another advantage. If your cable gets caught on something as the scope is slewing the USB cable will pull out of the connection at the pigtail. I've been using in on a Hyperstar setup, so it offers some peace of mind as a safety system. Can't imagine what would happen connected directly to the Lodestar and pulled at an angle.

    Well said Don - that expensive SCT corrector plate is gold-dust and needs to be treated so as accidents can happen for the unwary !

  8. Great work (too!) - EAA/video is THE WAY to 'see' the inordinately faint truly remote galaxies with clarity even from LP suburbia. We should heavily promote this. I haven't attempted eyeballing DSOs at the scope for ages as I want more than the eye alone sees. But for most, the eye to the EP, is locked into their thinking but from my perspective that like wearing dark glasses at night :-)

  9. Stick around long enough in the hobby and you're sure to get lucky:-) My first with a pic too on phortofilm was Comet Mrkos 1957 and 6 or 7 since with best (even seen from lying in bed!) were Hale Bopp and Hyakutake.

    Use HeavenAbove for current comets with star maps. Although none currently naked eye many can be captured in a few seconds camera exposure which suits me till the big one comes along:-)

  10. Woke at 5am and eastern sky crystal clear and dark - a beautiful sight. In descending order Venus, Regulus, crescent moon, red Mars and finally Jupiter best seen in 10x50 bins. Too early to see Mercury as unrisen. Awoke again at 6.45am with a bright dawn sky and only Venus, moon and Jupiter obvious and Mercury unseen even through bins.

    Keep watching tomorrow morning as the the moon moves near to Jupiter/Mars duo :-)

  11. I use my tablet to surf - as now -and my W7 laptop for Lodestar. I'm thinking of getting a Chuwi 10" Android+W10 and using LL under W10 for image capture etc. Firstly will LL run on such a tablet? OK it may be gimicky but my wife want to buy it for my birthday and it may be fun - if it works for EAA:-)

    Any advise appreciated:-)

  12. Rose at 6.20am this morning to look for the crescent moon high in the SE from the bedroom window and greeted by splendid alignment of planets. Brilliant Venus left of the moon and further down Jupiter much fainter by comparison. Tried some snaps but mostly blurred through camera shake. HeavensAbove showed Mars near Jupiter with Mercury close to the horizon but not seen. Only Saturn, still in the evening sky absent. Quite a view and around all week as the moon 'slides' down through the planets each morning:-)
