    My astro image winner

    Now that is very nice! Well done!! Makes me want to get to the southern hemisphere... ...I had an image printed in the mag. once and it lost about 3 magnitudes worth of stars Cheers Paul

    Better dark site ?

    Yes, Elan Valley!!!

    Observing from Teide ????

    Yes. Car hire essential. Works as a rest room and a wind break. Have observed from Mirador de Chio and a couple of 'sheltered' locations near the observatory. The light pollution isn't too bad if the inversion layer cloud is in place. Good luck. Paul

    "The brightest and closest it's been for many years" ?

    Mars did look excellent at about 30 deg. altitude around 23:00 last night. Using a TMB 92mm APO at ~ x195.

    M97 Does she exist or am I going mad

    Try M108 which is very close. Also try direct entry of the RA and Dec coordinates to get you there. It should also appear on a named objects list on the handset?? Good luck. Paul

    Conjunction and opposition

    I use this understanding for 'conjunction'... ...when 2 or more celestial objects 'appear' to be close for an earth based observer. irrespective of their real positions. Opposition is an absolute statement of position relative to the sun and earth. Cheers Paul

    just jumped ship from canon to Pentax

    Add one of these! http://www.digitalcamerareview.com/default.asp?newsID=5480&review=pentax+O-GPS1+astrotracer+pentax+k-3+astrophotographer+made+easier+and+less+expensive Job done! Cheers Paul

    Why are some things on Messier's list?

    If you are able to get out under a dark sky, doing a Messier Marathon via star hopping is great fun. The best Marathon season is late March! Cheers Paul

    comparing the size of deep sky objects

    Hale-Bopp got upto 40 degrees long. Moon is about 1/2 degree...

    First glimpse of the Explore Scientific 16" Dobsonian

    Hi Indeed, I wouldn't upgrade that primary at 1/6th.

    First glimpse of the Explore Scientific 16" Dobsonian

    Hi As a long time abuser of large aperture dobsonians I'd recommend at least 1/6 wave (gives a bit of slack on 'diffraction limited') and high reflectivity coatings. At least on the secondary. You don't want to be moving around all that heavy aperture without reaping maximum rewards When you get familiar with what you can see through large apertures, you do notice the difference. Spend, spend, spend... Cheers Paul

    New Supernova in M82

    New Supernova in M82

    Was under dark skies over the weekend. It was clearly visible though my 92mm TMB refractor. Also viewed through a 22" dobsonian. An obvious colour difference to the nearby star. Yellowy/golden. Don't now if this an attribute of the SN or caused by dust in M82. Cheers Paul
  14. The Orion SkyQuest 14" base will fit through a standard doorway, assembled or disassembled.

    Thick questions about dew and dew heaters

    The primary mirror in a newtonian becomes cool enough to create a cold boundary layer of air next to the mirror surface. Dew is formed from this layer. One method of preventing dew is to keep air moving across the surface of the mirror preventing the cold layer forming. Fans situated to the side creating a laminar flow across the mirror do this. A very low power heater is best for the secondary, that is used to prevent dew in the first place. Similarly a wraparound heater strip for refractors. HTH Paul

    m87 jet ..... visually ?

    Hi I think this is probably harder than the Horsehead to observe. Needs transparency and good seeing with good optics that can take higher power. I used an 18" Obsession. Another good one for the late summer/autumn season is Pease I in M15. Good luck! Paul

    Andromeda's actual size if it was brighter

    A bit of a simplification. As it gets nearer, you would think brighter, however the same amount of light is spread of an apparently larger object decreasing brightness per unit surface area. It wouldn't really appear 'brighter'. Don't think I'll wait Cheers!

    Good news for once ...

    For those wishing to observe from this area it is worth noting that the military at the Otterburn Ranges do light up the sky on a regular basis. The southern sky from the NNP can get quite lively. https://www.gov.uk/government/publications/otterburn-firing-times Probably not an issue from Kielder. Also the glow from Newcastle is less. Cheers Paul

    Elan Valley Dark Sky Bid Gathers Apace...

    Great news! Every bit helps. Have been observing from the Elan Valley many times. Just back from a week there only 3 hours of clear sky but magical as always. I've had slightly darker skies from D&G.
