  1. Hello! I am looking for variable star databse using which I can practice star light curves in spreadsheet programs. I am doing this as my statistics project where I can do visualization, little bit of error reduction etc. I did see a few ones like AAVSO, but they either need some specific job title or specific star etc. I need something to have in general, like here is the data-choose what star option you want etc. Thanks!
  2. Hello! I have been really inactive here, so apologies. Here are a few images of the Solar Eclipse, happened on 21 June 2020. It was annular, but partial from Mumbai region (around 60% covered). Maximum phase of the eclipse was at around 11:30 a.m. IST. This is actually onset of our 4-5 months of monsoon season, so getting decent skies was a tough part. Luckily got decent cleared patches here and there with occasional rains. I had to use whatever I had to make a comfortable view of the eclipse, thanks to the lockdown. I simply took a box, made a whole of the size of the eyepiece on one end, cut the opposite side and attached a paper. I had to do little bit here and there attachments for perfect angle. But was really happy with the results. One of the best experience was when I was seeing the Sun while it was drizzling at the same time. Thanks! -Rhushikesh Deshpande.
  3. Hello to all! Posting a photograph of the Summer Milky Way band that I took last week. However, I do not know how should I feel about this! This is when the band was right overhead, which is a rare sight for us and happens only when monsoon season is delayed. There was decent glow towards horizon but literally nothing at zenith. 19 degrees north latitude, around Bortle 3 level sky, taken using Nikon 5300, basic lens. And with this, I prepare to have no view of stars till September ends
  4. Hello to all! Just posting some of the images I took recently! (Total first attempt from someone who can't even hold a camera properly) I was out to conduct a public overnight sky observation event, which was the last event before 6 months of monsoon. For a lot of time, we had cloud cover too! These images don't include much of editing more than just some basic stuff in cellphone. I forgot to take the photos in RAW so either way I can't do much! Quite happy with the first attempt. Will improve even more in next season! Nikon 5300, with the basic 18-55 lens. Any suggestions appreciated! Thanks!
  5. Posting in this forum after too long! One of the first attempts at taking photos of the moon. All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there. No exposure. Basic editing in cellphone. Thank you! Suggestions highly appreciated!
  6. Hello! I'm currently in USA and thinking about getting Orion H-beta filter 1.25", to kind of complete my filter gear. (Already have lumicon UHC and O-III...both are giving nice views!) Any advice for H-beta filter? Price here is around 95$, including taxes. Back in my hometown it is doubled! So if it's worth then I'll go for it! Thanks!
  7. Finally managed to observe the Veil nebula on last Saturday! I remember spending too many hours searching for it during my observations. The milky way band in the morning came up really nice ,almost a continuous band from scorpious to Cassiopeia (managed to see that too!). Thinking about giving veil a last try, we pointed our skywatcher 8 inch dobsonian scope with 32mm plossl eyepiece and lumicon UHC filter and BAM! It was right there, bright enough to show it for first timers too! Looked like an arc or smoke chain coming out of matchstick. All The reports say that Veil nebula is an easy object, but I have had hard time seeing it all this time, while easily observing Flame nebula and Horsehead nebula through smaller telescopes. Maybe it's the real dark skies...or just some plain luck! Clear skies!
  8. The topic does come up little bit here and there, but not in details. I do explain more of basic though (Since mostly the crowd is from non physics background) It occurs that my main issue is that I don't know exactly what topics should I cover during the session (even though I happen to know the concepts). I need to make my session good enough that at least someone from the students should think about taking Solar Physics as a career.
  9. Hello! So I need little bit help to make my solar outreach events better. Usually most of my solarsolevents events have been for schools and little bit for general public But now I am going more towards college students and arranging events specific for solar observation. (It used to be more like complimentary with night sky observations) Since I am not a science student (learning physics by myself only), I don't have exact idea about what topics should I cover in theory. (Also what should I learn as well) Usually I take a projected image of the sun using my 90mm refractor and do H-alpha observation using my Lunt 50mm telescope. As for theory, I cover little bit about nuclear fusion, sun as a magnet, little bit about solar spectrum. If time allows then I refer Sun's images like magnetogram and all to have a better idea. Any suggestions would be helpful! Because it looks like I am still the only one here taking H-alpha observationsobservation. P.s. I will be putting up this question in solarchat as well. But more help will be better! Thanks! EDIT : currently I am thinking about adding a small radio telescope. Also, looking out for something to make so that I can see the solar spectrum much better.
  10. Hello! So I have been an amateur astronomer since last few years and now I see that so many people have asking me about general telescope suggestions. (Guess the next step will be helping to set up small observatories...Ah dreams!) We don't have many telescope brands available. The major brands that are available here are Meade, orion, celestron and skywatcher. The confusion starts to rise when the other party is interested in little larger scopes like 8 inch sct or 12 inch reflector with eq mount or dobsonian mount. Would like to know overall experience that you guys have had with these brands like optical tubes, mount, eyepiece etc. Sort of like "this is good, this is not so good" type. For e.g. I have used celestron 6 inch sct, 12 inch (sort of) sct and 102mm short tube refractor. Although I love their optics, I haven't had good experience with their mounts. Meade : Used their 8 inch sct with fork mount (and liked it). Used their 90 mm refractor and didn't like it much. Skywatcher has given balanced performance overall. Decent mount, decent optics, decent supplied eyepiece etc. Also, on the same topic, I am quite confused with how much importance does having a good telescope dealer has. As in we do have many dealers here, but many times I have experienced things like overpriced scopes, no decent guidance etc. If I suggest just one dealer with whom I hadam good experience then it looks like biased opinion.
  11. I know I am being a bad person but I am praying to let that Sunspot group just go away... We still have our monsoon season going on here and I have missed all the action! *my telescopes cry with me*
  12. Many times people ask me this question during sessions. Although I am not that great with answering using technical terms and explanation. I try to explain it using a torch (or a candle) and my hand. Just raise your thumb (Like you are giving a thumbs up) and extend your pinky finger. The tip of the Thumb is north pole and tip of your pinky finger is south pole. (You can do it using a ball...Just hold it in two fingers...upper one is your north pole and lower finger is south pole.) Then tilt it roughly to match the 23.5 degree. And now just go around the torchlight like earth. (Or candle...light source is the sun and your hand is the earth) (given that you used a ball held using two fingers) The point where your lower finger does not receive torchlight is summer solstice.(short nights in northern hemisphere) When your upper finger is not receiving any light, it is winter solstice. (Longer nights in northern hemisphere) These two point will be 180 degrees apart and 90 degrees from each point, you will have your solstice. (Would have explained much better with photos if I were not travelling) With reference to previous comments in this topic, you will get the idea. I guess the main problem is that we can't directly think in 3D so it's tough to visualize in our mind. For audience questions, you can do this right at the spot. Hope this helped!
  13. Anybody involved in Amateur Solar Research???(If there exists such thing!) Or any astrophysicist into solar? Would like to know about the instruments, process and well what exactly can be done overall... Reason why I am asking is that I recently saw on internet about an observatory (mainstream) in India having 6 inch scopes equipped with filters and if any projects are possible, they will be helpful for me. Thanks in advance! Never mind if it's a stupid question. EDIT: I did try to contact respective people but didn't get any proper reply.
  14. As we have our monsoon season going on, sky's total cloudy from June to October. But surprisingly, we got little bit of clear sky, enough to observe the Partial Lunar Eclipse. This was my first eclipse to see through my telescope. Following are the photos of the eclipsed moon through clouds. P.s. I am not a photography person so Never mind for poor quality work. Instrument- skywatcher 90mm f/10 refractor and cellphone camera. *telescope goes back to hibernation* Happy monsoon!
  15. Thanks for all updates! Actually the idea came in my mind after looking at Sun spotter scope design. I am not a great fan of using film or glass filter for white light as I have seen things going wrong. Projection method is really good if I am having a large number of audience and it's a pain to close the telescope after every few minutes because of heat. Sun gun design uses only 60mm. The UV/IR filter suggestion by moonshane is kinda interesting. Idea was to have a refractor on motor driven mount and if I am having a good sunspot then I will use the zoom eyepiece to observe it. On similar note,I have a small doubt. Maybe everyone is having a 60mm lenses with high f ratio because the longer f ratio will increase the image size and reduce the heat problem?
