Hey, made a short doc with an Astronomer at the University of Toronto who just recently found 10 super-agb star candidates... when there was only 1 prior. This has huge implications on how many supernova we can expect to see in the Universe and the elemental composition of the Universe. Check it out below! This project got us thinking about the implications of showing the scientific process in a new light. This helps with the new expectations of science communication for researchers. The scientific process never gets shown or properly explained. Discoveries in Astronomy is never astronomer looks through telescope then Eureka! A discovery! There's so much more to it then just that. There's hours and hours of organizing data, analyzing the data and writing the paper. So I hope the short doc somewhat does it justice and hope to get some feedback! -
Hi, I hope this is allowed. I took this photo today from the north of the UK around 5.40pm. The zoomed in image shows what has been picked up by long exposure. I took 2 images in the same place seconds after each other and this had moved down around 3cm (screen measurements). Could anyone give an idea of what this could be? Possibly noise but I would love to find out.

Wide-Angle Shot of Western Sky (16th April 2017)
Atlantean98 posted a gallery image in Member's Album
From the album: Wide-Angle Shots
Obviously it isn't the best of pictures due to the fact i live in North-West London, and I have a Fujifilm FinePix S9500, but i go to my local Nature reserve which borders the outside of London with Hertfordshire to take amazing pictures like this one! The Wide-Angle Shot is at f/2.8 and the exposure time of 20 seconds, the ISO Speed is ISO 400 and the focal length of 6mm. It was taken toward the western sky at approximately 20:00-22:00, on the 16th April 2017. -

One of my first targets but still trying to get a decent image - clusters are harder than they look to capture due to them being all stars so tracking errors and uncorrected optical problems are very quick to show up in the end result.© Aenima

In my search for Comets at the moment, I had a night outside on a clear evening last week. I cannot wait until Comet ISON makes it's way round. -
I seem to be getting these vector flares on some of the brighter stars, any ideas please? Explore Scientific 80ED FCD; 1.25 L'Extreme filter; Canon 250D modded; 1.25 filter wheel; OVL Field Flattener. I have tried with and without a filter, also with and without the filter wheel. I have just had the scope collimated as well by an astronomy store in the UK. I include two images, a single sub and a 62 sub stacked and initial stretch. Thanks Tony

Stargazers Lounge community, The sci-fi novel I wrote takes place in a binary star system and I'm attempting to fact check before handing over to my agent. From what I gather, there are S-type, P-type & T-type systems, but I'm having a hard time wrapping my mind around the orbital possibilities. Hoping someone's expertise can help! Would it be theoretically possible to have a planet in a binary star system where there is a daily "pre-sunrise" and a "pre (or post) sunset" due to the dimmer star? And could there be daily syzygy with the stars or might it need to be less frequent? If anyone can advise or has any suggestions, it would be so appreciated! Thank you!

finally sorted out the videos on my desktop machine so I could get the colour balance right Starry skies - 1000 x 5 second exposures over 90 minutes and 2480 raw exposures make up this Cloud timelapse over 8 hours as always best viewed on Youtube in full screen

Hi, does anybody know if stars differ in color when viewed through different sets of binoculars (ex. 7x35, 10x50, 11x80, 20x80)?

I saw another post similar to this on here and the replies seemed to be very believable and informative so I thought I’d ask here. For the past week or so I have been sitting outside at night between 10pm and 12pm and just watching the stars come out. I haven’t been using my telescope because I didn’t feel like I would need it. The skies have been very clear and the stars beautiful but I’ve been noticing some strange happenings in the sky. I’m not saying ufos I’m just wondering what these may be, so let me explain further. First my mother and I witnessed a singular light, white light flying through the sky. There were no navigation lights or sounds. Just a singular light flying by, we ruled out airplanes because it was two low to be one but was also way too fast to be a helicopter. I’ve seen them twice and they always seem incredibly high up and barely distinguishable from stars. They aren’t shooting stars because they fly completely differently. Another thing I have noticed are flashes, like stars that get bigger and then suddenly disappear, like a flash. And I mean completely disappear! Now I’m sure I’ve read of these things before in one of my astronomy books but I’m honestly not sure what they could be. They fly and react different to any aircraft or stars so I’m intrigued. They also appear as if they are stars and look like they fly or flash right next to real stars. Now I feel like I need to note that I know a lot about astronomy it has amazed me since childhood and I am a skeptic. My family has a long history of being in the airforce, mostly as engineers and creators of new technology so when it comes to lights in the sky we usually have a good answer, but no one could explain these sightings. I also live near an airfield so I don’t understand why (if these aircraft were from there) were flying so incredibly high up, so fast and so far away from the airfield, they seemed to come out of the night and fly off and back into the dark. It was also completely clear nights with little clouds during these sightings. I’m asking here because I believe anyone who reads this will have a good answer for me and won’t immediately ridicule me for thinking I saw a UFO. Please let me know if there’s anything you think this could be or any questions you have! Thank you so much for reading and happy stargazing!

National Geographic 90/1250 maksutov is my telescope and thanks for all the replies and support of my previous post it helped me alot and i figured out how to see the moon for example in beautiful quality but there's the problem i have. I can only see good views and a sharp sight of the moon but that's about it. Do i need a better lens that can zoom even more out or is this the limit of my telescope? Please let me know if you know a solution to this. -
With several clear nights over the past week, I've been playing with the Synscan Pro app (Android) in conjunction with a Synscan WiFi adapter on an EQ3Pro mount. I have to say I'm generally quite impressed. Much cheaper than buying a traditional handset. However, this evening I was trying to "creep up" on the Andromeda Galaxy by star hopping towards it via Mirach, Mu Andromedae and Nu Andromedae. Mirach was no problem but the other stars were not available for selection in the app. Am I missing something? I couldn't find any way to enter an SAO number or any other catalogue number to find the minor stars. Is this a limitation of the app? Or the adapter perhaps? Or is it me? Clear skies, Mark. -
Hi everyone! I recently came across an event that I think you would all enjoy! Here's what they had to say when I reached out for more information Join us in person for AAVSO's 110th Anniversary Annual Meeting at The Row Hotel, located just outside Boston, MA, November 5-7, 2021! The Annual Meeting includes a reception with an opening speaker Friday night, and two full days of keynote speakers, presentations, poster research and observing section discussions, and ends with a banquet Sunday night. Also experience additional in-person perks celebrating our 110th year! There will also be a 2-day Spectroscopy Workshop for beginner through advanced participants on November 3-4. Don't miss our keynote speakers on the 6th and 7th: Sara Seager - Planetary Science, Physics, and Aerospace Engineering MIT-"TESS Exoplanets and Beyond" Andrea Dupree -Harvard-Smithsonian Center for Astrophysics (CFA)-"The Mysterious Great Dimming of Betelgeuse" David Latham -Harvard-Smithsonian Center for Astrophysics (CFA)-"Spectroscopy of Eclipsing Binaries and Brown Dwarfs Identified by TESS" Joe Patterson - Columbia University- “A Network's Observations of Cataclysmic Variables” (working title) The event seems like it would be a lot of fun! I hope I was able to share something with you as I'm new to the stargazer's lounge. Best, Julia -
A very crisp and cold night. I added more luminance data and also collected some RGB for NGC 2841. There is now around 4 hours in L and an hour each in R, G and B. The subs are 114s at a gain of 139. Wikipedia: NGC 2841 is an unbarred spiral galaxy in the northern circumpolar constellation of Ursa Major. A 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined its distance to be approximately 14.1 megaparsecs or 46 million light-years. This is the prototype for the flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous. The morphological class is SAa, indicating a spiral galaxy with no central bar and very tightly-wound arms. There is no grand design structure visible in the optical band, although some inner spiral arms can be seen in the near infrared. The properties of NGC 2841 are similar to those of the Andromeda Galaxy. It is home to a large population of young blue stars, and a few H II regions. The luminosity of the galaxy is 2×1010 M☉ and it has a combined mass of 7×1010 M☉. Its disk of stars can be traced out to a radius of around 228 kly (70 kpc). This disk begins to warp at a radius of around 98 kly (30 kpc), suggesting the perturbing effect of in-falling matter from the surrounding medium. The rotational behaviour of the galaxy suggests there is a massive nuclear bulge, with a low-ionization nuclear emission-line region at the core; a type of region that is characterized by spectral line emission from weakly ionized atoms. A prominent molecular ring is orbiting at a radius of 7–20 kly (2–6 kpc), which is providing a star-forming region of gas and dust. The nucleus appears decoupled and there is a counter-rotating element of stars and gas in the outer parts of the nucleus, suggesting a recent interaction with a smaller galaxy. Equipment: Celestron 9.25 XLT at F10, Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope

I've been absent for the forums for a while as I packed up my telescope with an impending house move. Which has now taken place and the telescope will be retrieved from safe storage. However a few nights ago I sat out in my new garden looking at the night sky. I grabbed my trusty Canon 40d and set up my tripod. Attached are some of the images taken. -
Hey everyone ! Hope your all doing as well as you can be with this pandemic ! Im completely new to this stuff, im looking for some advice on the right telescope kit to buy. I dont want to be spending too much cause like im new and wanting to try it out, just hoping you guys have got some suggestions for telescopes for the value. Mainly wanting to look at stars (my stepdad passed away 3 weeks ago and my partner bought a "name a star" for him and would love to see it properly) and im interested in see the planets like the rings and stuff too Any help would be very appreciated ! Possibly below £100 the cheaper the better at the minute but dont want it to be so cheap and tacky that i can only see the end of the garden through it lol Stay safe everyonr -
Hi all I have been imaging M45 and have come up with this form of issue with the stars. It almost looks like I have left (and I did think this) the Bahtinov mask on, however I didn't. This is not the first time I have noticed this star issue. Any ideas? This is my equipment: Explore Scientific 80ED Apo Triplet; Explore Scientific Field Flattener; Canon 250D mod; 2in UHC filter; 60mm Guidescope; ZWO ASI120MC-S.

stars Jupiter Sky & Star Shots
mark117h posted a topic in Imaging - Widefield, Special Events and Comets
Hi guys/everyone. Well viewing has not been great over my area lately so i took to my camera to see if i could get some shots in of Jupiter with the stars around it, i shot these images with my NIKON D5300 and the standard kit lens of 18-55mm 3.5-5.6 DX, i was getting bored and have been wanting to try and do the milky way shots that you see everyday and look truly great, although i was not aiming for the milky way, what i was trying to use as my center point was Jupiter, i was quite amazed at how many stars i was picking up considering the great street light of heavensvile lol slap bang outside my window, anyway my shots are below if anybody is interested in taking a look and offering some advice. Also forgot to mention that some of the shots was taken with my Tamron 70-200mm lens, but most was shot with the 55mm kit lens i got with the camera. Cheers Mark.
