  1. I am waiting impatiently for your report! Happy sightings! Alex
  2. I wish I could see that but, seeing the aurora as south as down to Greece, that would be very disturbing! I am planning to see it at least once though it's on my bucket list.
  3. Ahh thanks for sharing your experience! Sadly a 12" scope is way far from my budget right now, let alone a 16". I still want to get a good solid go-to mount first because while it is fun to star hop, when you are in light polluted skies, the experience is not that enjoyable!
  4. Thank you very much for this information! I have already started looking at it!
  5. Yes, that was exactly what I meant, thanks for clearing that up. I realise from your posts that I am slightly behind on our capabilities with respect to what we can image, as I thought that we could not even see the other planets, just infer their existence from dips in light curves. I have some studying to do!
  6. While a 39m telescope is by no means miserly, I have been wondering what the necessary apperture would be required to view the nearest planet. It turns out that the necessary apperture would be 200 Km, which is veeeeeery big compared to what we can build today. So I would not expect any ground-breaking results, unless a major step up in optics and computing occurs, like the array used to image the black hole, I think for now there won't be any visually striking new images. Also with such a large telescope, I think skyglow would be a limiting factor.
  7. Hello Dusty! I live in a part of Greece near Athens, which means I have severely light polluted skies. I would classify it as a Bortle 6-7 ( https://en.wikipedia.org/wiki/Bortle_scale ). I own a 130mm reflector and with it I managed to separate the colours of Albireo. The thing is that since they are stars they are easier to see and discern their colours because they produce their light and are pinpoint sources. From my experience, I have found out I can discern colour of up to mag 5 stars. If you want, I can go on a binary star search and report my results as to how far down I can push the apparent magnitude and still notice the difference in colour. I will however re-iterate the aforementioned point, viewing throught the eyepiece of your telescope will be a lot different than the astrophotographs you may have seen. A good post that was recently suggested to me was this ( https://stargazerslounge.com/topic/196278-what-can-i-expect-to-see/ ). Do not lose your enthusiasm, though. The universe is a sight to behold and there are many things to see in it! Sure, light pollution is very annoying, but when you finally get that glimpse of the item you were hunting down, it is even more exciting. I remember my excitement when I managed to get a glimpse of the Sombrero galaxy. Plus when you finally get to a dark site you will be able to discern many more things from that hunting experience.
  8. Thanks! I have had my seeings of open clusters, they were very nice! Especially the Sagittarius star cloud. I will check out the nebula now that you told me!
  9. Hello all! Following your suggestions I went on a stargazing adventure last night! I focused on Albireo and the easiest planetary nebula I could find, which was the ring nebula. Albireo's orange and blue stars were great and as appeared in all their coloury glory. The ring nebula however was not coloured. I had difficulty even noticing structure. With averted vision I was able to make out the ring, but that meant that no colour was available. Even that way however, the ring was a sight to behold!! I tried viewing Bode's Nebula as well, but that was very faint as well. I think I have a severe light pollution problem at my house, sadly. I think I'll organize an excursion soon to another island with a better sky! Is there anything else you think I should try to view?
  10. First of all, WOW so many posts, thank you all for the insightful replies! I am delighted to find out that it is possible to see faint hues and more, when it comes to DSOs. My initial expectations were that it was not at all possible, so this is a very pleasant surprise. I managed to get a glimpse of the Omega Nebula, it was an uncontainable thrill to see the internal bright triangular portion of it. Sadly, it sits at the skies right above Piraeus and Athens, so the light pollution is literally something that depresses me (I sometimes look at the hills around me and see the skyglow, it's like the sky is gray and not black). I am sure the reason it appeared orangey was because of that and not its actual colour. I was unable to see the lagoon and eagle nebula because of this. I am gonna try my hand at planetary nebulae, but I am unsure if my 130mm newtonian would be able to see them. I hope in the future I will be able to upgrade my gear and get the observations flowing much more easily. Thank you all for the tutorials and links, I will be sure to read them. Seeing michael's observation summary, a new question has arisen. What about supernovae? Can you see colour in them? What is the most colourful/ contrasty object you've ever seen?
  11. We have all seen in the internet and many of the people in the forum have taken themselves, beautiful cosmic photos of many deep sky objects, like the deep red lagoon nebula or the colourful eagle nebula. However, from what I have learned here, when we are observing with a telescope and are fully dark adapted, the objects are so faint that our eyes are not great dark colour cameras and are unable to use cones and therefore use rods to sense the light coming from them. So my question is, is it possible to see deep sky objects in colour, especially nebulas, like they appear in photos? I'm refering to a scenario where you are at a very dark site, with very little atmospheric disturbance and with a very good telescope. If such a scenario exists, what are the requirements?
  12. As a fellow noob I can share how I separate them. I do it with the help of my computer or my phone. I have not discovered yet how I can identify them if I see them without any help. If anyone knows, I would be VERY interested in learning it! With my computer I use the software stellarium which shows you how the sky will be at night or at any time of the day. ( It even shows you how the stars will look like in the future so I had a blast looking at how constellations will change over time). There has been (recently as far as I can tell) an online version of stellarium, but that is not the same as the one you can download. The differences however, have not influenced me at all, However I prefer my phone, which I can easily take outside when viewing. I use the stellarium mobile plus app (paid). There are free options as well. Star Walk 2 shows the 4 jovian moons but since it has a paid planets expansion, if I can describe it as such, I doubt it will have many more. If I remember correctly, Star Chart does not show them, unless you purchase them. You can purchase an expansion for most of the apps which will show the location of most of the solar system objects. Here are some screenshots from Stellarium (not the online version,Edit: Whoops, sorry for greek characters didn't notice them), Stellarium mobile plus and Star Walk 2.
  13. At least Thursday through Sunday, you get the sunshine you wanted!
  14. As a positive vibe, according to chaos theory, it is hard to make accurate weather predictions for more than 3 days ahead, let alone two weeks. So don't lose your hope yet!
  15. Hi Alan! Sorry for replying so late, I have been caught up with work. Thanks for the tutorials, once I find some free time, I will put them to use and let you know how it went Alex
