HOW TO LOCATE AND OBSERVE M3
ฝัง
- เผยแพร่เมื่อ 28 เม.ย. 2024
- M3 or Messier 3 is a globular cluster in Canes Venatici. It is best seen in May in the northern hemisphere. It is 34,000 light years away and is magnitude 6.2. There are no bright stars near it to allow star hopping but it is just about half way between Cor Caroli and Arcturus. In this video I'll show you how to find it and I'll give you some observing tips and show you what it looks like in binoculars, small telescope, and medium telescope-- a Dobsonian Telescope and a Schmidt-Cassegrain Telescope.

I especially enjoy when you're at your desk or table explaining stuff.😊
Thank you. I appreciate your kind comment. Thank you for supporting my little channel.
I spent two full nights observing M13. I was amazed at the details that became apparent with longer spells at the eyepiece. The propeller was clearly visible.
This topic interests me and all but I really watch for the ASMR Tsula serves. That's why I subscribe. Peace to all.
Thank you and peace to you as well.
Yes, thank you Tsula for all your very informative videos! You know you stuff!
Thank you. Thanks for watching.
haha as soon as you smile and welcome everybody to your video, I smile and laugh too. You are hilarious and awesome. your awe, energy and sense of wonder is infectious
Thank you. That is so kind of you to say. You made my day.
Best astrophotography channel, Tsula regards, from Bogota.
Hello to Bogota and thank you very much!
Hi Tsula, your films are so inspiring and informative. I’m inspired and can’t wait to get out there, dogged by heavy cloud cover here at present! Thanks so much for all the work and effort you put into your films it’s really appreciated. Regards, Linda
Thank you, Linda. It makes me feel good to know I am inspiring someone to get out there. Thank you and I hope the clouds clear for you soon.
Thanks Tsula, I really enjoy your videos. 😊
Thank you. I'm glad you like them.
Another great video! Really like your excellent sketches!
Thank you so much!
Nice! Thanks Tsula.
Thanks, Ron. By the way, is your goto Dob a Skywatcher? A guy was selling a goto 12" Dob on Craig's List and I seriously considered it but it weighs 100 pounds fully assembled and I really questioned whether or how long I would be willing to lift that much into my car.
@@tsulasbigadventures Yes, it is a Skywatcher with GOTO. It is quite heavy with the base. The scope itself is not that heavy.
i agree M3 is a very nice globular thats aslo bright not too hard to find even without goto scopes.
I was amazed to learn that M3 has more stars than M13 but M3 is still very impressive.
@@tsulasbigadventures yes but bit futher that why its bit dimmer cheers still get GC
Great video and guide , M3 and M13 rank high on Northern observing nights
Thank you and I agree!
When compared to m15, m22, m5 and omega centauri, not to mention m13 and m92, I think m3 ranks the lowest.
However, M3 is the first globular cluster to rise. The one we settle for while waiting for the time that m13 is high in the sky.
M5 has a nice granular quality, m22 is just massive, easy to resolve in smaller scopes, and m15 is just plain amazing in a 10" or larger at high magnification.
Omega centauri is spectacular, but that isn't happening in Montana, and probably not in Northern CA either.
The first time I saw omega centauri, about 20 years ago, I just happened to stumble across it on one of my early observation sessions when 15x70 binoculars on a tripod was my main instrument and I would head to areas along the coast to look put over the pacific because there was no light coming from out there, and one spring night while looking low along the horizon I saw thus big mostly circular haze. I didn't know that's what it was because it didn't quite resolve into stars at 15x and my eyes were not yet very experienced, I thought it was probably an edge on spiral galaxy, since the globulars I usually hunted in the binoculars were all much more compact and more like a little snowball. I would usually go up to turnouts on the Ortega highway in those early sessions. By the time I got a telescope I knew were a lot of things were in the sky.
In general, globular clusters are my favorite type of objects, but I don't spend a ton of time on m79 in the winter, with all the stuff in orion and Auriga to look at, but when I had my c11, m79 was still better than no globular to look at.
Tsula, this was a great video since it conveys how to find M3. I liked the sketches you did for each of the telescopes. Love your channel since I always learn something:). My only and first telescope is a 12.5 inch F5 solid split tube Discovery on a beefier stable mount (still have the original) since I’ve only been in this hobby for only 3 years. Keep the videos coming:)))
Thank you! I wasn't familiar with that telescope. So, I had to look it up. Looks nice. Does having a split tube mean you have to collimate more often or it doesn't matter?
It holds collimation very well and only a few minutes to do it before observing. High magnifications are not a problem. I wondered before buying it and read that several cloudy nights users say it holds very well. The original mount is smooth but not rock solid so modifications would be necessary. I was lucky to buy it on Cloudy Nights classifieds showing a second homemade mount with the scope that was superior in every way. I would have still purchased it with just the original mount since I could make some mods to stiffen the mount easily. I also installed DSC but most sessions I try to locate the objects since it’s so very rewarding. The 5 spaced out 100 degree Ethos eyepieces I have is a blessing on my un driven telescope. I could only purchase them one at a time since they are expensive. Clear sky’s:)
@@jeffrystehle3960 OK. It sounds like a nice purchase then. I know what you mean about those Ethos eyepieces. They make finding the target a lot easier but they are very expensive. My 10mm Ethos was stolen and I have not replaced it yet. Clear skies to you too.
This was lovely. Thank you Tsula.
Thank you. Thanks for watching.
Good video, globular clusters I think are the only objects I prefer to see on an eyepiece than astrophotograph. Simply expectacular. Here in the southern hemisphere we are blessed with omega centauri and is stunning on a 10" dobsonian. Is very big, it can cover your entire field of view with not so much magnification. Greetings from Chile!
Thank you and hello all the way to Chile. I've never seen Omega Centauri but if it fills the entire field of view it sounds like something I should seek out one day. And I agree with you that globular clusters look even better in the eyepiece than a photo.
Nice sketches!
Thank you!
Total optical immersion into globular clusters are cosmic baptisms.
Yes! Well said.
Tsula, have you ever thought of adding a PVS-14 to your observing arsenal? They are pricey, but you make such good use of your equipment it might be worth the expenditure.
I'm not familiar with it. Is it something that you add to your telescope? Or you use it in some other way?
I just went outside in a Bortle 7 sky using a Celestron/Vixen 80mm refractor. I could resolve some of the outer stars but the core was a grey fuzzy ball.
Good job on resolving stars with an 80mm refractor in a Bortle 7. Not bad. Such a beautiful object to observe.
@@tsulasbigadventures I owe it to the quality glass in these old Japanese refractors.
I’ve seen M3 several times over the past couple months from my bortle 6/7 back yard with a 134mm Newtonian. My best views seem to be around 70x magnification where I can almost make out stars, but not quite. Higher than that and it becomes a darker and fuzzier ball
Will being at a dark sky site help with resolving those stars? I do get the chance to camp at bortle 2 and sometimes 1 sites in the summer here in Colorado. Also high elevations at 8,000 to 10,000 feet. This will be my first time out there with the scope so don’t know what to expect yet.
Great info, Tsula! Wow, what a beautiful sunset that was. Have you always had that SV102, or is that new? Beautiful scope. I'm anxious to get my dob out of the closet and do some visual observing -- the poor thing has been in the closet all winter!
Thanks, Greg. I bought that 102mm a long time ago and wasn't using it much after I got the 203mm SCT. But lately I have been using it a lot more. It works great for looking at the sun with my Quark and for viewing large DSOs that don't fit well in the SCT. Your poor Dob is in the forbidden closet!!! Get that thing out!
I like these deep dives into individual objects.
I wondered if Messier had failed to resolve stars in M3 because he was using a poor telescope, but apparently he had one of the newly invented achromatic models. He discovered M3 in 1764, whereas the achromatic design was patented in 1758, and his four-inch refracting telescope, his favorite instrument, had a relatively short focal length, of about a yard, something not possible with single-lens models (which needed an extremely long focal length to avoid distortion - hence the "aerial circus" phase of astronomy). So I'm as baffled as you.
The more I read about Messier, the more I suspect he just missed things through being a bit slapdash about observing generally.
@@barthvapour He was mostly interested in comets. He was famous for it - the French king had praised him as "ferret of comets" - and his interest in astronomy had been sparked by seeing a naked-eye one. But his catalogue, despite its careful drawing of the Orion nebula, certainly has an odd construction, with experts asking why he included, for example, the Pleiades. On the other hand, he observed M3 more than once (with his achromatic refractor - that seems clear from the notes in the catalogue) and said it was "always very beautiful." So who knows?
Hi Tsula. I know you are an expert on eyepieces, so I hope you can give some advise to a beginner :)
I have recnetly got my first telescope, an 8" Newtonian f/5. With it I bough medium rebranded eyepices 18mm and 5mm, both 60 degrees AFOV. But now I already wanted to try a Tele Vue, to see what the best can do, and I bought one - the Delos 10mm with 72 degrees AFOV. It is very very good and really sharp, but I find it very difficult to place my eye acuratly when using the Tele Vue. It's like I most place my eye very precisely both in distance and on axis to get the full view without the black circles. It's was distracting. It was also like I could sense the secondary mirror doing something to the view.
My two question are:
Sensing the secondary mirror: Is this a tradeoff to this type of scope.
Difficulty placement of eye: Is this because of the type of eyepiece (focal length and/or AFOV)?
Hoping to learn something :)
Dark skies :)
Hello: Congratulations on your first telescope. 8" Newtonian was an excellent choice. I know exactly what you mean about having to get your eye at the exact right location to even see out of those eyepieces. Some are better than others but from my experience all those wide field of view eyepieces have that same issue. I think it's just the tradeoff for getting those incredible wide field of views. It has to do with the wide field of view and not the focal length though the shorter focal length ones do seems harder especially when you are at those high magnifications. Your other issue about sensing the secondary mirror I don't think I have ever experienced. Does this only occur with that particular eyepiece? I am not sure what to tell you about that issue but as for lining up your eye precisely it gets easier the more you use the eyepiece and to me personally I just love having the giant field of view and so I just put up with the annoying matter of getting my eye lined up precisely. It's much easier to line up your eye on the longer focal length eyepieces. I have a 36mm Baader that has a 76 degree FOV and that is my goto eyepiece and it's not hard to line up my eye on it. But as you go to the higher magnifications it gets harder.

Thank you, Tsula :) That is nice to know when I am looking for the next eyepiece. Eyepieces are awesome and I now understand why so many describe them as personal. I have the Panoptic 24mm in sight, but not until the nights get dark again. I live in Greenland so the nights don’t get dark at all, so I only have the moon and the sun for now. In fact we couldn’t see the big show of northern lights this weekend. But luckily we can see them all winter :)
@@TH-camr-ku4nk You're welcome. I was thinking about whether the aurora could be seen in Alaska. I went to Fairbanks in January to see the aurora but the aurora season ends there in April because the sun barely sets.
I own a panoptic 24mm that I use on my 10" Dobsonian. That is a great eyepiece. Good luck to you.
