Re: Flying over the sun eastern limb in a 280mm scope.

The halpha is clearly much better defined than the 393.4. If you look at the top portion of your calcium image it is fairly blurred(this could simply ge from the low intensity transmission of the pst filter) Not complaing, its far greater than what ill be imaging and pretty much anyone else on the f...

Re: Calcium K-line doublepass by apollo lasky

A little info, i had placed the chroma 402 filter in front of the negative element, and i had a tiffen 102mm linear polarizer over the 90mm objective. The intensity was still over whelming my sensor. So either the rotational polarizer on the camera to directly decrease the transmission is going to b...

Re: 393.4bp0.1 doublepass results(it works!!!!)

Now I imagine If i get the proper negative lenses and proper positive lens, this thing will work pretty amazing. But right now the magnification is just too great for my little meade scope. (if i had a larger camera sensor that would broaden things up a bit) I think Using a negative 300mm lens is th...

Any ideas for bf (not itf) replacement?
I know what the replacements are, but unfortunatley i signed a confidentiality agreement and ccannot reveal it publically.

They are definitly available and out there “off the shelf”. Its a very common part. (Hint)

Re: What do you think is the most versatile high resolution solar telescope design?

all that matters is strehl ratio. my 2 cents. This is what makes or breaks a solar scope. The tec140 is .99 strehl at 546nm, so it will produce flawless convection cell images, with astro solar film. (8,204.02 United States Dollars, complete scope) the istar 150h-alpha is .98 strehl at 656.3nm, so i...

Have fun guys, ill be gone for two weeks.

Dont let anybody convince you something is not going to work, Just doit yourself and find out yourself.
90% of the time the person saying it wont work, are just not capable of anything but paperwork.

Re: Experimenting calcium imaging with small refractors

You can pop the achromat lens out if its cell and increase the air space gap with cardboard strips to Decrease blue astigmatism , A bit of trial and error plus tedious guesswork involved but it works.

Use a cheap scope!

You are too hard on yourself, these captures are awesome! I love the hydrogen jellyfish, not a reflection at all. Perhaps a Google 5g skybender baloon?

so i just got done conceptualizing/prototyping a new skybender. It is 40% smaller, and now 100% modular. Crazy.

Re: Narrowest 393.37 ever by Apollo Lasky

okay i just ordered the baader planetarium double polarization filter. (its possible the single polarizer will work but i gotta try the double) I will probably be able to test this before i leave for colorado because agena is real fast at getting items to me, just need the sun now. https://agenaastr...
