Cuto100200 Posted May 7, 2020 Share Posted May 7, 2020 Was just wondering what DSO's are good to see in summer, that aren't too hard for beginners to locate? Moon is full currently so I guess it washes out a lot, but this is more for when the moon is no longer quite so prominent This would include, globular and open clusters, nebulae, galaxies, just about anything really, with emphasis on beginner friendly I have an 8" dob Thanks for any suggestions Link to comment Share on other sites More sharing options...
John Posted May 7, 2020 Share Posted May 7, 2020 There are loads provided that you are OK to wait up until it gets properly dark. The Ring Nebula (M57) in Lyra and the Dumbell Nebula (M27) in Vulpecula spring immediately to my mind. Both straight forward to find and observe with all scopes from 100mm and upwards. My favorite Summer DSO is the Veil Nebula in Cygnus but you need a UHC or O-III filter to do that justice. It's very hard to see at all without such a filter ! The 2 magnificent globular clusters in Hercules, M13 and M92 should also be on the "must see" list. I'm sure others will come forward with plenty more ! 1 Link to comment Share on other sites More sharing options...
Stu Posted May 7, 2020 Share Posted May 7, 2020 Definitely wait for the Moon to be out of the way a bit more, but would suggest the following: M44, the Beehive Cluster and the nearby M67, both open clusters M3 and M5, globular clusters M13 and M92 are also getting better placed now, two more globulars You could also try the Eskimo Nebula in Gemini and also the Ring Nebula in Lyra. 1 Link to comment Share on other sites More sharing options...
Louis D Posted May 8, 2020 Share Posted May 8, 2020 The Double-Double, Albireo, and M17 also come to mind. I don't know how far south you observe from, but there's also M7, M8, and M22. 1 Link to comment Share on other sites More sharing options...
ScouseSpaceCadet Posted May 8, 2020 Share Posted May 8, 2020 (edited) John's mentioned two of my faves, the Dumbell and Ring. The Ring Nebula especially is a little treat in a small scope. Later in summer, M16 The Eagle Nebula is quite low but observable without filters. Install Sky Safari and have a play.

ScouseSpaceCadet Posted May 8, 2020 Share Posted May 8, 2020 (edited) That's a minefield I don't want to tread on but, approximately a 70-120mm refractor, 90-127mm maksutov, 114-150mm reflector I'd consider 'small' & capable of providing reasonable views of any of the above under the right conditions. I'm sure someone will put me right and/or disagree. 'Small' is of course relative. One could consider any telescope that isn't a huge professional instrument housed in an observatory as 'small'. I've dug out the Wiki definition and I wasn't so far off: https://en.m.wikipedia.org/wiki/Small_telescope Edited May 8, 2020 by ScouseSpaceCadet Wiki link. 1 Link to comment Share on other sites More sharing options...

I struggled to see it when I had just a 60mm scope but that was a long time ago and I may well not have known what to look for. It is a small object at low power and easily overlooked. I have seen the Veil Nebula with a 70mm as well but I did need the help of a UHC filter and it was rather faint. 1 Link to comment Share on other sites More sharing options...
Cuto100200 Posted May 8, 2020 Author Share Posted May 8, 2020 How difficult is it to fully split double double, do conditions need to be near perfect? and what sort of magnification would be needed? Also thank you all for the suggestions, got a list now lol Link to comment Share on other sites More sharing options...

Also thank you all for the suggestions, got a list now lol With a 100mm scope, about 100x and upwards will do it. The stars in the 2 pairs are close together though so you need to look carefully to see that they are pairs of double stars. A larger aperture and the easier they are to split. 1 Link to comment Share on other sites More sharing options...

I'll have to try splitting it with my 70 ED, 90 APO, and 127 Mak just for fun this summer to see what's possible with smaller scopes. I have a feeling the splits won't be as clean.
