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!

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

Hello I am new to astronomy, and recently purchased a Celestron Starsense Explorer LT 114AZ, and just for a start, I used the finderscope to locate exactly a random star, and I looked through the eyepiece and just saw a blurry white image. I was using a 25mm eyepiece lens, and then decided to put on the 2x Barlow lens with the 25mm lens, and nothing changed. Is this normal? What should I do to improve? Thanks.

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.

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. -

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. -
I’ve been looking up st the Stars with Telescopes I’d put together from various other scopes, but late last year I decided to get more involved with it. I’ve purchased at least 15 books on Astronomy. I’m starting to piece together how the start Charts and Math and which tools are best used on the subject of Astronomy and so far self taught. I don’t know anyone else that’s doing it. I stumbled into this site looking for something totally unrelated and just see what’s here. I’m primarily interested in just about everything on the subject. Maybe I should have did this early. Hello everyone.

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

I often love to play youtube lectures in the background as i work on my home improvement projects, only problem with that is many times my attention gets so focussed on the computer screen that i fail to see paint dripping from my brush onto the carpet, that did happen!. Anyway, here's a great lecture from the Perimeter Institute for Theoretical Physics which is just a couple hours drive from my home about the weirdest stars known, some fascinating facts here with a dose of humour.

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. -

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. -
This is KIC 8462852, the star which some academics are speculating may possibly have 'alien megastructures' orbiting it creating a media stir. Other large telescopes are now pointed at the star and SETI is on the case with radio telescopes. I still think we'll find out it's some natural phenomenon but whatever is discovered will be exciting. 10 x 2 minute exposures at 800 ISO11 x dark frames11 x flat frames24 x bias/offset frames (subtracted from flat frames only)Guided with PHDProcessed in Nebulosity and Photoshop

I noticed that my stars are a tiny, barely perceptibly, bit egg-shaped yesterday. For a change, instead of crying into my pint-glass, I decided to investigate: There's a script in PI called FWHMEccentricity. I used that on a couple of my subs and found that I have a median eccentricity of about 0.49. Not knowing if this was particularly bad, I went off and analysed some professional images of of the internet (and some from the posters on SGL, who will remain anonymous). Would you believe it, many of the images were coming out at about 0.4 - 0.45. So I conclude guess that 0.45 must be about the threshold where the human eye/brain can distinguish between a circle and an ellipse. How round are your stars? does it bother you if they are "not quite there"? Can you tell that I am bored with the cloudy skies?
