  1. Can you let us know a little more? Any particular targets that interest you? Do you need the scope to be easily transported or carried any distance, or would you need to carry it down stairs? Where would you store it? Scopes range in size and portability quite a bit so it can affect the best choice. As a starter for ten, without knowing any of the above, I'll say the Skywatcher 150P. £9 over your budget, not small but a very decent scope. I'm sure there will be plenty of alternate suggestions which are well worth considering, so take your time! https://www.firstlightoptics.com/dobsonians/skywatcher-skyliner-150p-dobsonian.html

    Pop the data into this calculator and you can see why it is tricky from an average site. At SQM mag 20 it is tough in a 6 inch scope say, mag 18.5 and it would be impossible. Compared with M81 and 82 which are much easier. http://www.bbastrodesigns.com/VisualDetectionCalculator.htm
  3. DSO Imaging With 150PL - M81

    That's a great image, especially using such a long f/l scope, can't be easy to guide!
  4. Welcome to the new Celestial Events forum! This is a short guide to detail how to use it, along with the new Celestial Events calendar. These instructions will evolve as we go along to make sure everything runs smoothly. The Celestial Events forum is a specific section to post up about less predictable events which happen at short notice such as: New solar Active Regions Proms about to lift off Super Novae/Novae Close Asteroid passes The intention is to have these in one place rather than scattered either in the Astro Lounge or the various observing sections. This means that you can subscribe to this forum specifically so that you will be alerted to new content and have the best chance to observe or image the event. You can also post up if you happen to be the first to notice something. Celestial Events Calendar This is for predictable events which we know are going to happen such as: Lunar and Solar Eclipses Lunar X visibility Visible GRS transits Shadow transits Occultations Planetary conjunctions/oppositions As a mod team we will populate this as much as possible, but please do add things that you notice that are missing. They will go into a moderation queue to be approved for entry into the calendar. You can subscribe to the calendar so that you will be alerted about events created in it so you won't miss anything! Do drop me a pm if you have any suggestions as to how this might be improved, but otherwise please do enjoy!
  5. F10 apo's?

    I still suspect you got away lightly Dave
  6. F10 apo's?

    I've always just been frustrated by the fact that there are no review units in trustworthy hands. In theory they could be great, but that's all it seems to be currently. Olly, I actually saw a Cape Newise 8" scope at AstroFest being used to demo a somewhat agricultural mount . I very nearly spent my hard earned cash on one of these, so glad I didn't!

    It really is the skies that make the difference, they are all visible in binoculars if the skies are good enough. I saw M33 and M101 both first in 15x50 binos.

    I don't think you will see any significant differences in Sigma Orionis as they are all blue-white or blue stars. I do like it as a multiple though, the tiny fourth star is great to pick up.
  9. F10 apo's?

    Very much unproven as far as I can tell.

    I've often struggled to find these two when using a Newt, but find them quite easily with a refractor. Not sure why!
  11. You can work out how much larger as a multiple without PI just using the radius squared because the PI cancels out eg 60mm aperture = 30 x 30 x 3.14 = 900 x 3.14 150mm aperture = 75 x 75 x 3.14 = 5625 x 3.14 so the 150mm has 5625 x 3.14/900 x 3.14 =5625/900 = 6.25 times the surface area Same principle for all the others. What are you trying to work out?

    Have a great trip!
  13. Got it , at Last ☺

    Nice one! M1 took me years to find, quite literally and in the end it was easy, once I tried under a dark sky. Same story as you!
  14. I found that without a shroud, my breath was constantly causing air currents in the view, so have found using one very beneficial.

    Already there, just need one of the shorter dew heater tapes, and some form of controller of course. The little single channel dual port one works well. https://www.firstlightoptics.com/dew-prevention/astrozap-dew-heater-tapes.html https://www.firstlightoptics.com/dew-prevention/hitecastro-single-channel-dual-port-dew-controller.html
