Hello everyone! I'm new here. So my question or questions may sound kinda ignorant. The answers may be a little obvious. I love this site  and have read so many comments and learned so much!

Anyway, I have a Canon 60D camera with live-view. I have a Tasco reflector with D=114mm F=900mm(this maybe a little small?). I will be using a T-ring/adapter and with this I hope to capture many decent photos. But for the eclipse, do need a special filter for the scope or the camera or both? If so, could you give suggestions where to get this? Thanks to everyone for any help!

You need a solar filter for the front of the scope. In general there are 2 available makes - Thousand Oaks and Baader. Both are a heavy filtering film and they fit over the front of the scope.

For visual they are termed something like ND5, for imaging I think they are ND3. The 3 and 5 refer to the power of ten that they attenuate by so one is 10**-3 and the other is 10**-5 (The superscript seems not available here?). So very very heavy filtering.

The visual 5 is likely the better option, simply you can alter the camera to take the difference into allowance and then it does for you to view the sun.

The catch is that EVERYONE wants one and last I read someone could not buy one from anywhere - you are sometuning like 19 days away.

They can be made but again you need the solar film, A4 or letter size is how they are supplied.

Start going through the scope retailer sites and see if anyone has one of the right diameter and if they have them in stock and can get one to you on time.

Just reread the post, the DSLR may not managed to get the sensor and focal plane of the scope to coincide. Unfotunately s DSLR and a scope does not mean it will just work nice and easy, there is a mechanical requirement as well. Have you tried the DSLR out on the scope yet ?

Thank you for responding so quick!  Thanks for the info.  About the ND, is that Neutral Density? Because I have ND filters I use for many outdoor photo projects(of course, they are only 58mm). Maybe B&H or Adorama has them? About the sensor deal, I've seen some folks mention using an extension to get a better view. But to answer your question, No, I have not tried the camera on the scope. Haven't received the T-ring and adapter yet. But I also am getting the extension with it, just in case. I guess we'll see.

Hi pixelperfect:

It's definitely possible that other dealers might have them, but make 100% sure it is a solar filter you are using. It should be ND5 (which is useless for anything except the sun) and to properly block the IT and UV wavelengths also.

The most important thing is that be an aperture filter - unfortunately you can still sometimes buy the ones that fit inside the scope like a regular astro filter. Don't be tempted for a second- they regularly crack under the heat, which equals a permanently ruined camera or a permanently ruined eye.

Don't know what others think about the following suggestion, but provided you do not look through the viewfinder at the sun you might be able to get away with a heavy ND5 welding glass as an aperture filter. If you only used the live view that might work, and probably won't damage the camera.

The best option would be to try for the Baader solar film, but in the current climate that might be tricky. If you can source someone else's off cuts though you could scrounge enough for a 58mm filter or similar.

Billy.

I agree with above, you definitely need a filter for all moments in the eclipse until the full eclipse when the whole sun is covered by the moon, that's the only time your photos will be better without a filter.... before and after that moment you're risking to frying your sensor without a filter.

      Hello There
      I've used so far a really cheap telescope that you can look at the moon, but its time for a big upgrade.
      What I'm looking for:
      Go To
      Photo / Picture Capturing
      Looking at Planets (no blurry images)
      looking at nebulas
      looking at galaxies
      different eye peace's
      possibly connect to pc software for screen usage
       
      price range up to 1500$
       
      I've no idea if I'm out of my mind with my wishes. but for me the market and numbers and features of the description for the telescopes are a bit overwhelming.
      So I hope that someone can recommend a telescope for me
       
      Thanks Jubi

      I almost hesitate to ask this but ahem, here goes... 
      My EBay white light filter turned up today & I scurried out into the garden like an excited child on Christmas morning. 
       
      After a bit of faffing I have it clamped to the ST80 and using the equally cheap but pleasingly effective SV-Bony pinhole projector finder (can’t believe it just slotted in and is aligned as there’s no way to adjust) there is a lovely big, crisp, solar disc. 
       
      Can’t see any sunspots though - and here’s the dumb question - is there just nothing doing today or am I missing a trick? 
       
      Any beginner tips on white light observation gratefully received...

      Hello,
      I've been on these forums a couple of times for the last 2 weeks and ive found amazing advice, on telescopes, mounts and eyepiece. Besides reading countless of information on the internet about various equipments; pros and cons; and i got some queries about how to upgrade my setup.
      My original purchase was a 15x70 Celestron Binoculars last year, and boy ive seen amazing things with it, specially globular clusters, Jupiter and Saturn and the Orion's Nebula; for me these were amazing; i still use them given how easy it is to look at the sky with them and how bright and full everything looks.  A couple of months ago i got a 70x400mm Gskyer Telescope with an AZ mount (The cheap 99$ one that Amazon is displaying on all its adds for the last two months)  it came with a 25mm and a 10mm eyepieces as well as a x3 barlows (which i didnt even count as part of my scope as it is too bad quality and i havent managed a single decent view with it).

      Currently My Celestron Binoculars (x15) seem better for visualizing the sky than the 25mm eyepiece (x16) (things seem a very bit dimmer). And since the Barlow is a "no go", the 10mm (x40) eyepiece is what i really use, it has decent zoom and detailed views , it is my go to eyepiece most of the nights.
      However from reading all around, ive read that most of the stuff that come with the Telescope (aside from the scope itself) are actually really bad quality, specially no name brands without even webpage, so if i were to maximise my telescope i should update some of those items.
      -Recently i ordered a new Start diagonal to replace to default one (ive heard on Refractors its usually the weakest link next to eyepieces) as well as an economic x2 Barlow lens
      Keep in mind i recognize my 70mm cheap telescope will not suddendly become the Hubble Telescope, and that it doesnt matter how hard i push it, in the end such a low scope will be bound to hit its limit pretty fast, thats why i avoid 70$+ eyepieces and barlows for now.
      I expect to keep using this telescope for a good couple of months; at least until around August, when Jupiter and Saturn are more in the night sky, rather than morning.

      Now, im very satisfied with my current telescope; while the phone mount is garbage and the phone weight and the sound of my heartbeats pretty much shake the telescope out of position, as well as how cheap the mount is; it still gets the job done for seeing interesting stuff in the sky and i have managed to do some AP for some of the globular clusters, bunch of 1-2s images (with the wrong lens), not the best, not even good pictures; but decent overall for my equipment. I am currently interested in stargazing in general and some minor AP (as i dont have a camera, currently an Iphone 7s with the mount) Buuut im interested in borrowing a camera for the low sky photos without a telescope.
      I do most 97% of my Skywatching on my backyard, i live in a small country, there is some light pollution, but i can see the pleiades and the orion's nebula core on the naked eye most nights (so i guess its not that contaminated lol)
      Now; currently i like finding stuff by myself and show it to the other people around me who cant be bothered to find the moon in the sky, so setting up, finding and seeing stuff is part of what i like. 
      With all the above in mind..... Id like to plan ahead for my next purchases.
      First, im thinking a x3 barlow lens (to replace the original crappy one) and a 15mm lens (to have a bit better view than the 10mm, but less spread than the 25mm) in two or three months (with this id be able to check if my new eyepiece outperforms my default ones, but given the quality of the scope, i dont expect this to be noticeable).
      And Afterwards id love to get a new Scope, but im not quite sure what i want... and i would like some advice and help in choosing my next Scope upgrade.
      -I entered with and im liking the refractors; however i dont wanna spend 300-400$ on another refractor that is 20-30% better for triple the price
      -Ive heard really long focal lenght might bring some distortions; and also make the scope much bulkier, annnd most importantly i know that magnification is not everything; so a 1000mm long tube would prob bring too much magnifications for me to use properly on my backyard skies. So i think id settle for a maximum of 600-700mm.
      -Originally i was againts Newtonians in general, those inverted views scared me, i have a hard time of my own with my finderscope. Then i found out that Reflectors are the name of efficiency as they have more value per aperture than refractors; and as someone once mentioned "There is not really up and down in space, you will get used to it" annnd its true... save for references on the ground, like buildings, trees and mountains to help you locate where you are in the sky; once you are on it, you dont need right ups and downs.
      -I did see some 90mm Orion's Refractors as well as 90-102 Celestron Astromaster Refractors (these are 350-400$)
      -Im thinking a 130mm reflector is what im looking for; i think the 130mm aperture is a nice upgrade for my 70mm, and will keep me occupied for quite a long time; ive read about Orion SpaceProbe 130EQ and Celestron Astromaster 130EQ (ive also read, Power Seekers and Astromaster's are made out of pretty much garbage lol) Ive read that the main issue is the constant collimation required for them; but ive also read its something that can be learned and once you get used to it; its a pretty easy thing to do to keep getting amazing views.
      -Ive also seen people recommending  6-8'' Dobsonians; i know the deal with them; if anything i could aim for a 6'' one i found a litter under 300$ ive read they are amazing values for their aperture
      So, TL;DR: I have a 70x400mm Telescope, im new to stargazing, im really amazed and excited by what im seeing with my current scope, but would like an stable upgrade before the end of the year that will last me a year or two. I am interesteted both in regular and deep sky stargazing and astrophotography;  im not currently interested in an motorized mount; could deal with a regular Equatorial mount. But overall i am looking for  more aperture (100-150mm) to have clearer views; than focal lenght for zoom.

      Im also open to the fact that at one point i might have to get a scope for stargazing and another for AP; but would like an upgrade that could help me all around for both while i get initiated.
      ------------------------------------------------------------------
      Sorrry for the Huuuuuuuuge post, i was very excited while writing it; please let me know what you think and if there's anything else you'd want me to add to help understand my situation, thanks in advance!

      I currently have a ZWO 178MC OSC planetary camera.  Everybody tells me that I need to get a mono chrome camera for solar imaging. I have narrowed it down to two cameras the ZWO ASI178MM or the ASI174MM.  The ASI174MM is quite a bit more expensive and I am not sure why?
       
      I have a Lunt 60MM HA f/7 Solar scope and looking for recommendations.
