Great video with clear instructions. Thank you very much! 👍👍👌 *I hope you saw today’s total eclipse. It was cloudy in central Texas but saw the whole event through breaks in clouds. Unbelievably amazing! 🌝🌚 Best wishes!
Thank you! I'm glad you were able to see the eclipse! We ended up going to Vermont to beat the clouds and I was successful. I posted some pics in the "Community" section of my channel. I'll post more soon.
Very well done Thank You! I especially liked how you showed using a glue stick to fidst attach the film to one piece of cardboard and then using the hot glue gun to attach the second piece of cardboard to complete the "sandwich".
Thank you! And good luck! The 10" sheet at Agena is sold out. I'll update my link to point to the 8" one. The 4" sheet is still available for now. Let me know if you have questions.
@@Naztronomy thanks, I finally made mine and tested it and it works! For me the cardboard that I used did not stay together well with just glue, so I ended up putting tape all around the edges to hold it together, and that seems to be good
You might find cutting a round hole to eliminate diffraction spikes a useful improvement. Straight edges in the light path are to be avoided. Also keeping the film flat might improve image quality. That might be achieved by gluing the film to the cardboard with the film on a flat surface and the cardboard which was cut out, placed back in the hole, on top of the film.
I just tried this so I will have plenty of time to practice - and it works! I don't see how to upload a photo in the comments, but I would be happy to do so if someone will tell me how that is done?
That's really great to hear! You can't upload images to the comments directly. What you can do is either upload it to your google drive and post the link here or you can use another image hosting service like Flickr or Imgur. You can upload there and then post the link for people to follow. Hope this helps!
Yep! They are safe as long as the filter is in front of the telescope and doesn't have any kind of damage. You can read the FAQs from Thousand Oaks Optical here: thousandoaksoptical.com/faqs/ I've used the filter through both my 60mm refractor and 6" SCT visually and for imaging without issues. Let me know if you have any more questions.
Thank you and Good question! Short answer is not really. I don't think you'll notice a difference, although I haven't tested this with photography, just visual but I suspect the quality, color, and contrast will be the same. Longer answer is that the manufacturers recommend that the silver coating face the sun. That helps reflect some of the sunlight and keep temperatures down a bit. I think this is especially helpful when it's hot outside. I usually make sure all of mine has the silver coating to the sun. There are some filters that are black-black polymer. Those don't matter at all.
argh! was trying to follow this video, but realized all of the additional things around the front end of a newtonian made it very difficult i ended up spending quite a long time fitting the construction paper around the focuser and other knobs and such, and eventually got it to work
Glad you were able to work it out! What kind of Newtonian do you have? I have a 6" newt and I don't have anything in the way that would have blocked me so I'm curious what you have. My focuser is a good 3-4 inches from the end so I don't usually have to worry about that.
@@Naztronomy orion xt6 the focuser is probably like 3 inches away from the end of the tube, but there were other problems, mainly the secondary mirror vane knobs and my telrad mount
@@clayel1 Ahh yeah, I looked up the Xt6 and I understand now. My newtonian is an imaging newt so the tube extends about another 3" past the vane knobs, and then another 3-4" to the focuser. Good to know because I was supposed to help my friend with an xt8 with a solar filter, I assume he will have the same issues. Thank you!
@@Naztronomy ah ok, makes sense btw i read online that even with a sturdy support its possible that a gust of wind could come in just the right spot, so i secured mine down with 3 pieces of tape
YOU LOOK VERY SIMILAR TO SOMEONE ELSE WITH A TH-cam CHANNEL YOU SURE YOU ARE NOT A DOUBLE OR A CLONE OR PLAYING DIFFERENT CHARACTERS UNDER DIFFERENT ALTERS ??? 🤔
Your principles are ok in construction, but I don't like the liberal use of glue. Perhaps you should use more care with measurements and cutting the lines accurately. I thought solar filters did not like finger prints! You are handing the solar filter incorrectly. These filters are very expensive so more care is needed in handling it !
Solar sheets don't care about finger prints. Unless you're touching it and leaving a ton of residue, handling it this way won't affect the light transmission. It's a good idea to wash your hands or use gloves if you're worried. And the point of the video is to show that this type of a setup is NOT expensive. The only care you really need to take is to not damage the actual sheet. Make sure there are no tears, holes, or creases that can allow sunlight to seep through in order to remain safe. And you can use tape if you don't like glue.
Watch my review of 4 of the best solar eclipse glasses: th-cam.com/video/7eSdPO9Awu0/w-d-xo.html
with the eclipse just days away, i finally assembled my own from materials purchased months ago. Here's hoping i don't get an overcast Monday!
Better late than never! Clear skies!
I like the simplicity of keeping the filter flat. Thanks!

Thank you 😊I've been sandwiching my solar filters since 2012!
thank you, this is awesome! I'm going to try it for the April eclipse

@@ukuleila Cool! That sounds good, I've made them using just tape in the past.
Wishing you clear skies during the eclipse!
@@Naztronomy you too! ☀️
Make sure the filter is secure on the end of the scope so that it doesn't blow off while viewing!
Definitely! I have a follow up to this video planned before the next eclipse so I'll reinforce that.

Terrific, thank you. I am making one in the morning! :)
Awesome! Good luck 😊

Thank you! Good info!
Can use the filter for naked eye view thru the telescope?
Yep! They are safe as long as the filter is in front of the telescope and doesn't have any kind of damage. You can read the FAQs from Thousand Oaks Optical here: thousandoaksoptical.com/faqs/

Great video! When mounting the filter does it matter if the black is towards the lens or the silver coating? Thanks
Thank you and Good question! Short answer is not really. I don't think you'll notice a difference, although I haven't tested this with photography, just visual but I suspect the quality, color, and contrast will be the same.

@@Naztronomy Thank you!
Nice DIY Solar Film!! 👍🏻
Where did you find such a large sheet of filter, 6in square on Amazon cost me 15 dollars
Check the links in the description, I've been keeping them updated. The 12" is out of stock but the 10" is still there for $24.

Great idea 👍🏼. Thanks!
Thanks 😊
