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.
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.
Hi all I’m just looking for advice on upgrading telescop. At the minute I’ve got a Meade ETX 125 and had some good views with it so far. Mainly Moon Planets and brighter clusters. However I wanted to see more Galaxies and nebulas which is a much to ask for a F15 scope.
im looking at second hand Celestron/Meade 9.25” f10 s With maybe a focal reducer and Sky-Watcher 10”-12” F4.9 dobsonians which is the better choice?
Hi, I'm a beginner and I want to buy something for my telescope. I have a Bresser 6 inch Newtonian(750mm focal length) I have 2 lenses, 9mm, 25mm, a moon filter and a 2x barlow. What would be the next thing to get? I was thinking maybe a solar filter, a light pollution filter since i am stuck at home, idk. What are your thoughts on this?
I'm not experienced with LRGB imaging, so thought i'd give it a go on M81. However, when i combine the 4 individually processed integrations i end up with horrible colour hues across the image - they're all aligned and wotnot. Am i running into the issues of light pollution (inside the M25), which i can only remove with aggressive DBE application? Individual files attached.
