    Think that was a good shout mate.  Looked like some sea mist rolled in last night from where I am in Hamworthy and Creech, being quite high, would have been covered I reckon.  Not sure how long it stayed though.

    Cheers, that's good to know. In the end, the sky was spectacular over Piddletrenthide. Cracking session :)

    Hopefully we can get a few sessions in this season. 

    Speaking of which, I know it's a little short notice, but Sunday's looking good, weatherwise, and I'm planning to head up to the carpark above Creech for the evening. Anyone else up for that?

  3. Wow! @prusling that's an amazing photo. And @AdeKing too, the sunset was fantastic. I too had a great time last night. Although we had no luck with the Veil neb, I got Jupiter (amazing sight in the brief moments of stillness), Saturn (still too low to see the Cassini division, but spectacular nonetheless), M57, M13, and then, by about 1.30pm, the southern sky cleared completely, to reveal Ms 4, 6, 7 & 8, 22, 69, 70 and NGC 6652 (those are just some of the clusters and objects I saw that I could easily identify!).

    M8, the Lagoon nebula was fantastic! Bright structures, with dark lanes running through, nearly filling the fov of my 20mm ep at x60. The last 20 minutes of the evening I spent scanning through Sagittarius and Scorpius with my 10x50s will stay with me.  When a large, bright patch appeared to the right of Sagittarius, I at first thought it was the return of the clouds, but in the binos it appeared full of stars, with dark dust lanes running through. I'd never seen this starfield so clearly defined and bright!

    Will definitely be heading back there again soon.

    Cheers Ade, Peter!

  4. Hiya,

    First of all, a light bucket dob isn't the best tool for viewing planets. It'll be better on fainter objects like galaxies, faint nebulae, etc, where gathering light is the important factor. For already bright planets magnification is more important than aperture. However, seeing conditions affect the view, and there's an upper limit to the amount of magnification you can reasonably use and still get crisp views. This limit isn't imposed by the equipment, necessarily, but more so by the atmosphere (and associated humidity). Your 3.6mm plossl is already giving you what many regard as the upper magnification limit useable in the UK (900/3.6 = x250). 

    EPs with better glass would give better views, though (in terms of more contrast, sharper images, wider fields), but it's unlikely you could use more magnification as well.

    I wouldn't recommend spending large sums yet on EPs. You can do better than stock items and plossls by spending only 40-50 quid on BST starguiders and the like (these will offer a much better view generally than the EPs that came with the scope. However, the upper limit to magnified but still sharp views remains ...

    When I'm viewing planets like Jupiter and Saturn, I'll try x240 (which is the most I can use with my scope / EPs), but the best views are usually obtained around x150-x200.
