  1. Good stuff - sub arcsec can be a challenge unless the seeing is excellent! I'm still waiting for someone to come up with a triple-triple! Chris
  2. Good seeing here, but haze plus Moon wiped out all but the brightest stars. Good to see Vega rising in the NE, even if it was twinkling madly. Mr and Mrs Fox seemed to be enjoying the nearly full Moon, or maybe it was one of my neighbour's hens. Chris
  3. ...and of course Castor is itself a triple, one of the most spectacular in some ways. Chris
  4. There probably isn't a sufficiently good word to describe the view that you sometimes get on those magical evenings when the sky is clear, the air is still and the mozzies have gone to bed. Several years ago, I watched Saturn for nearly an hour through my 180 Mak as it was one of those evenings, with Hubble-like detail and stunning soft banded peach colours of the disk. That's why we all continue with this hobby, despite the long cloudy periods and the neighbour's security lights! Chris
  5. The best view I've found with my 180 Mak for looking at DSOs is with the 38mm Panaview 70 degree FoV eyepiece. If there is vignetting, it's certainly not obvious to me and the view is glorious. The eye relief is not the best, but certainly ok. Chris
  6. I tried a few doubles in Orion, but the seeing here was barely average, at least to the W. Transparency was pretty good though, so I spent some time on M1 before the -5 degrees got to me. The elongated shape with a hump in the middle was fairly obvious at x70 (180 Mak) but more detail eluded me last night because of the relatively light sky. When it's higher in the sky I often see a bit more detail. The joy though of having a clear night........ Chris
  7. This is of course true, but I don't think you can beat the laws of physics - agreeing with @Vlaiv in an earlier post. Coming back to the original theme, for much of the recent Mars season, I had my 4" f13 (Vixen objective) frac out alongside my 180 Mak and there was a consistent benefit in using the larger scope on nights with good to excellent seeing. On poor nights, the frac gave a better (more contrasty) view but when the seeing was good enough, extra detail was apparent with the Mak even though the contrast was slightly less. When I bought the Mak it was after using a long focus frac
  8. Some interesting comments on OOUK, and certainly the first horror story has been seen on this forum before. Was there ever a reply from them giving their side of what happened? If at all true, it will not exactly encourage sales I would have thought, so an explanation or a denial would seem to be in order? Chris
  9. I have a large tablet with SS6 Pro on it - I use it inside a darkened electronic component bag to cut the brightness further. Chris
  10. The Cambridge atlas is good & I love the charts which work well in conjunction with SkySafari. Chris
  11. Very nice detail! Chris
  12. I was looking at Sirius last night (180 Mak) as I too had noticed that Sirius wasn't twinkling as much as usual at 52 degrees N. The reason of course is that the air was still (good seeing) with very little movement due to thermals - I doubt if air pollution has much influence. Through the scope, Sirius' companion (the Pup) was easily visible, as were stars E & F of the nearby Trapezium and details on the Moon (Plato's craterlets) were visible. A rare night of excellent seeing. Mind you, it was bloody cold. Chris
  13. Brilliant here as well last night for Orion and Leo doubles - trouble is, the wind was still strong and it was below zero. An hour was all I could take.... Chris
  14. Another vote for this software (it is reviewed in AN this month). I tried the demo copy free trial, and than bought it after a few days playing because it was so good. The best results I've had so far have been with images of Saturn (image attached), Jupiter and crater detail on the Moon (images attached). Well worth a try. (images with a 180 Mak). In the Saturn image, Encke is much clearer after processing, the inner rings more obvious, and noise levels on the planetary disk itself quite a bit lower. Chris
