  1. Tonight, the (very) thin crescent of the Moon is a few degrees east of the pair Venus-Mercury. A beautiful sight! Edit: oh, and C/2020 F8 (SWAN) is in the neighbourhood too. But that's a tough one probably.
  2. What a wonderful, beautiful, colourful and detailed image! Thanks for sharing!
  3. Where? On that website? That's right, it's just ratings and descriptions but very informative.
  4. Take a look at this interesting website comparing the effect of different kind of deep-sky filters on a number of well-known objects. As it turns out, a UHC type filter performs really well on both the Veil and the Ring. This matches my experience with the DGM NPB. The UHC is more of an "all-rounder", the OIII only excels on certain kind of nebulae (mainly planetary). H-Beta is another specialised filter, performing really well on an even smaller number of objects (De Mairan, California and Flaming Star for example).
  5. Another amazing fact is that this 6-star system is actually part of the Ursa Major Moving group or Collinder 285, a stellar association thought to have a common origin and similar age. Most other stars of the Big Dipper are also part of this group, as well als 'stream stars' like Alphecca (CrB) and Menkalinan (Aur). They are not gravitationally bound anymore, but share their motion in space and chemical composition.
  6. There are many apps around that forecast cloud cover, but they are all based on just a few weather models so many apps will basically show the same data in different ways. Most use the global GFS weather forecast, because it is easily available and free to use. It's not that bad when it comes to predicting clouds (source), but its grid size is quite large. It's best to combine the forecast with actual cloud cover satellite images to get the best idea of the conditions for a given night.
  7. Hi and welcome, congratulations on your first telescope! I'm pretty sure you'll have lots of fun with it. It would be helpful if you posted a link to the telescope you've got, so we can see the specs and give you more in-depth advice. For now: the 10 mm magnifies more than the 20 mm (twice as much). A higher magnification is mostly useful for observing planets, details on the Moon, double stars or small deep-sky objects like planetary nebulae. Lower magnification gives a wider field of view, so this is usually better for larger objects like other nebulae, open clusters or some galaxies. But it's best just to try them both out and find out what works best for you. The finder scope gives you even less magnification, so you can use it to point your scope. Usually you aim a manual scope by matching the view through the finder with a star chart or app. Then, once you've found the correct location, you look through the eyepiece so you can observe the object you're interested in. Yes, the barlow magnifies the view even more, in this case 3x. You insert the barlow in the eyepiece holder, and the eyepiece in the barlow. Your 10 mm eyepiece then effectively becomes a 3.3 mm eyepiece. The actual magnification you get depends on the focal length of the scope (we can find out if you provide a link ). If it's 600 mm for example, a 10 mm eyepiece magnifies 600 / 10 = 60x, with the barlow 600 / 3.3 = 180x.
  8. The summer Milky Way has a lot of treasures worth observing during the nautical darkness. And don't forget about noctilucent clouds. Not really astronomy, but very beautiful!
  9. I think your post would be a bit easier to read for a non-native speaker like me if you inserted a line break or punctuation here and there. I'm really interested to understand the point you're trying to make.
  10. I second the suggestion to go for a Sky-Watcher Heritage 130. Since you like to see the Moon in detail, the larger aperture of the Heritage over the StarPro will give you a higher resolution and because of that, the ability to see more detail. The simple mount and the red dot finder allow you to locate objects of interest quite fast. Although the maximum theoretical magnification for the scope is around 250x, this depends to a great extent on the atmospheric stability ('seeing') and most likely will not be achievable on most nights. It is however useful to buy a barlow that will fit between the telescope and the eyepiece and effectively doubles the magnification. The supplied 10mm eyepiece will then provide a magnification of 130x, perfect to study details on the Moon.
  11. Another vote for the Action EX 10x50. Bought them partly based on Steve's review. Nice, solid binoculars with a great performance both day and night.
  12. What a wonderful, detailed and colourful image, thanks for sharing! Lots of background galaxies too. I didn't know about these either, are they in the NGC?
  13. Maybe you can find a second-hand pair? I think they are great, clear views and wide field of view. But I don't know how they perform compared to cheaper options.
  14. Measurements are usually done in zenith, right above your head. Results depend on the type of SQM device you have. I own an SQM-L and they have quite a narrow field of view: they measure the brightness of a narrow piece of sky where you point the device to. I usually take a few measurements around the zenith to avoid the light of the Milky Way or other bright objects to influence the results. The 'classic' SQM device has a larger field of view and will be affected by skyglow of nearby towns.
  15. Ah, I saw that thread but didn't realise it was yours. Yes, a lot of choices (welcome to the world of stargazing ). I own an Action EX 10x50 and it's wonderful, but maybe above your budget I think?
