I just found out that you can observe the sun via telescopes for personal use in affordable price, pic related, filters cannot be removed so it has no other purposes than sun observation

But something bothers me. Sure, seeing sun spots, prominences and ejections is fun, but what is the interest in it, aside that it will keep you busy for few hours, and then the telescope will be not used?

Just like every kind of hobby astronomy, it has no purpose. There are always devices around that are much, much better than whatever you are using. The sun's spots are very closely observed by lots of instruments, both on earth and space. So if you don't have any fun with looking at it over and over again, I suggest you don't buy one of those instruments. You can probably build something like that on your own anyway.

It's just cool man. You don't need a substantial reason to see the sun from upclose. It's just like eating icecream. You do coz its fun.

I wonder if you can use those in a polluted sky of a big city, if the sun is visible of course.

bump for interest

I have pic related. You may also want to also check out the Lunt which I think is a similar price.

What's nice about a solar telescope is that the Sun changes. It's always different when you look the next day. I use it more than other telescopes simply because it's so portable. I may spend only 10 mins each time I get it out but it comes out a lot.

You can also try astrophotography with it if you have a webcam. It's hard but it can be done.

I've used it in a big city and it makes no difference. It needs to be bright sunshine to use it, if pollution is that bad then maybe not. Light pollution obviously isn't a problem. If in doubt try your local astronomy club, someone will have one you can try.

did you took pics with your device?

in terms of quality of observation, how much details you can see?

I can't find stuff that I did with my PST, I think t's on my other computer. I took this however with a friend and our university's Coronado which is the more expensive model above the PST. It's not great resolution but it shows you the level of detail you see. It really show prominences because you need slightly longer exposures.

The red colour is just added, the CCD was black and white. I have some videos off my PST, I may try processing them now.

This is quickly processed from my PST. I need to mosaic to get the full sun with my small camera but the other frames are shit.

looks really nice.

when you look it, it's just black and white?

>> No.7577158

No, it's deep red. The cameras I was using don't detect colour however.

H alpha scopes see one very specific colour which selects the atomic emission line of hydrogen. All other colours are discarded so you don't burn your eyes out.

Again if you've curious try your local astronomy club.

Actually thinking about it it's more pinky red.
