Solar scopes are usually small aperture because there is so much light intensity, that there is no need to gather more light. For that reason you can use the smaller aperture often available on the lens cover. That way you can save on filter material.
You get better and sharper details with more aperture with a newtonian. The price difference is insignificant. A dedicated solar scope is another world, though.
Good, I liked the idea, I am going to buy these stuff and I will make homemade filter for my 8" DOB to see the next solar eclipse on 25 October. Many thanks
Very interesting.. my telescope has a smaller diameter (about 5 inches) I will be 3D printing my frame ring for my film. And will sandwich the film between 2 layers if plexiglass for a consistently flat "lense" (to keep waves out of the film.).
Cool. I have made a ghetto filter compared to your solution. Wrapped the filter onto OTA, temporarily held it in place with a rubber band, and hand 3D printed the rim with the hot glue gun. It naturally created a perfect fit rim of a removable filter. It works great, but it looks "homemade" ;) Even a sticker would not hide that fact 😂
$1 .50 emergency blanket. On a 80mm Use 2 layers for visual viewing use 3 for photography.. on bigger scopes you may need one more layer. But you get a ton of filters out of one blanket. And rubber band it over your objective. A lot of times if you pull the due guard and press it over your filter it will hold and stretch it perfectly tight. Your welcome. 🇺🇸
@@DobsonianPower been using it for years. Do what you want but I still have20/20 What do you think your approved filters are?!? Alumized Mylar or glass. Your just not paying the price and your thickness is adjustable..

They won't. You have to take the measure of the tube outer perimeter and buy a mold which can fit that measure. Also the sheet is not enough, has to be a bigger one.
You can turn around that building a filter that doesn't cover the full telescope aperture, which will be more than 10" (10" is the mirror). Use your imagination with materials like cardboard and use the larger sheet you can find. As the Sun is too bright, you will not loose many details.
@@DobsonianPower yep but moon is without filter and very far from scope whereas filter is immediately in front of scope.I focused all the way out and still could not reach focus.
Olá Tiago1 Sigo o teu canal regularmente, e aprendo bastante contigo! Há uns meses atrás também fiz uns filtros solares, com papel baader e cartão, mas não utilizei a abertura total do meu dob de 8''. Pelo que li, não há necessidade de utilizar toda a abertura, uma vez que, mesmo com o filtro a luminosidade é elevada. Não sei se se coloca também a questão do aumento da temperatura dentro do telescópio. A forma como adaptaste o filtro ao telescópio é excelente. Vou refazer o meu filtro com as tuas dicas. Por aqui não consigo enviar as fotos do meu filtro. Também sou do Algarve. Obrigado e boas observações, cumprimentos
Olá José. Maior abertura favorece o detalhe dos spots e não tem qualquer problema de temperatura, mais um mito entre muitos. O resultado é excelente. Abraço.
@@bruhbruh7240 It's not the filter i recommend. Mine is very strong and had no holes at all. However, they say that if we make accidentally a hole, we can use the small debris from the DIY to cover the hole so i suggest you to do that. It will not degrade your views and it will solve your problem.
... and to finish this... This channel 'is'... About dobsonians therefore Tiago helps 'people' that cannot afford a telescope to get the easiest to use that at the same time cover most usage including planet. Therefore this video reflects that and many astro retailers Know that. In UK they are avoiding to sell GOTO upgrade fir dobsonians, guess why? ££££££ greed! I use sct at present, but also use refractor and dobsonian intially which I still have. My future will probably be a large goto dobs in a fixed place or with a motorised trailer ! EASIER... especially as you get older....
There's a market for everybody. It's better to allow an entry point with less money and later, eventually convert them in a hobby addict like us rather than place them a financial wall that many people will just turn the back to and we all loose. Hopefully brands may see that.

That is why I built my own 90mm solar scope, ultr asavings...
@@DobsonianPower I used a self built filter for my old dobsonian many years ago and it was good! No doubt!!
Dobsonian solar scopes use unmirrored glass to reduce the amount of light hitting the eyepiece.

nice ideea with the cake mold!
👍👍
your pictures look better than any other youtuber! you get the best pic of m33, pluto etc
Some are better, some are not. The Dobsonian is very good i small and distant objects, deep sky.
Thank you.

I use that as a dew shield. I wouldn't never use it to watch the sun, only approved filters.

It's safe. You should have the filter inserted and a shroud.
Hi Tiago,
Do you think the items you ordered will fit a 250mm/10" dob?
They won't. You have to take the measure of the tube outer perimeter and buy a mold which can fit that measure. Also the sheet is not enough, has to be a bigger one.
Do you know the right solar filter in size for my Dobson 10 inch? ( I can only find it for 8 inch and below)
You can turn around that building a filter that doesn't cover the full telescope aperture, which will be more than 10" (10" is the mirror). Use your imagination with materials like cardboard and use the larger sheet you can find. As the Sun is too bright, you will not loose many details.

👍⭐️✨️
Amazing idea! My eyes thank you!
👍👌
How do yo get it into focus, mine never can reach focus with filter.
It's the same procedure as you were focusing on the Moon. If you can do it with the moon you should be able to do it with the sun.
@@DobsonianPower yep but moon is without filter and very far from scope whereas filter is immediately in front of scope.I focused all the way out and still could not reach focus.

@@DobsonianPower Obrigado Tiago, abraço!
I tried something like this with my dobsonian and it melted holes in it, thankfully it didn’t damage my telescope but is there a way to prevent that?
What do you mean about melted holes?
@@DobsonianPower after using it for a few minutes, I noticed some holes had appeared in the solar filter. They looked to be burn marks.
What filter sheet did you buy?
@@DobsonianPower Orion film solar filter.
