Re: Why is the PST etalon not sold on its own?

i will add this extra note, you CAN buy the lunt pressure tuner etalon which has the single stage of protection pre installed and it is not removeable. It is the red glass ir/uv energy ejection safety feature pre fitted directly infront of the etalon itself. However you still need the lunt blocking ...

Re: Why is the PST etalon not sold on its own?

And yes, you are correct. All solar filters are dangerous to an extent when not used correctly. That being said, the reflection of sunlight on your car is also dangerous if you keep looking directly at it. Some people get careless, and carelessness is entirely the reason why they are not sold. Nobod...

Re: Surface contrast in CaK for various filter bandpasses.

You know, since we are all seeing this perhaps we can all publish a new terminology. I assumed they were from iron because i first began seeing them at exactly 393nm, which is pretty much right ontop of the photosphere. Now i have also seen them in the sdo aia1600 and sdo1700 but never read any publ...

Re: Calcium Chromosphere By apollo lasky

I agree with Alexandra, it is very difficult to image CaK proms, well done i figured out how to make them 25% brighter, here is at f8.3 90mm objective. no additional lenses. no barlows, no telecentrics, no powermates, no collimators. Calcium takes prominence imaging to a whole new level. calcium pr...

Re: Narrowest 393.37 ever by Apollo Lasky

I pointed out these filaments in p_zetners topic on contrast. Hearing about contrast is getting quite old to me, So if you are wanting to spend 3000$ that is all it takes to get "contrast". Providing the filaments here at f8.3 should be enough to change the entire imaging scene, but hey what do i kn...

Re: Surface contrast in CaK for various filter bandpasses.

So yea here are solar minimum calcium filaments seen at f8.3 with no other optics. These will be prominences by monday or tuesday. The Contrast argument is getting quite stale. In with the new, out with the old. Spend the $3000 on three of my chroma filters, and you a golden, operating with less tha...

Thanks, appreciate your comments It would be better if I had a non rusted PST objective though You may be able to find a replacement, 40mm x 400mm is a very common part! You can get one specific to red light to match performance. Should ge a simple swap out https://www.newport.com/p/PAC085AR.14 Her...

Re: Surface contrast in CaK for various filter bandpasses.

Guys, the chroma filter shows filaments. Take a harder look and examine the pictures better. They are not as dark because solar minimum just doesnt do it justice. But they ARE there, as thin path like wisps. They resemble an animal path traced in grass. 95% transmission is a hard beast to tame. Try ...

Okay guys i had to get this information out before i leave. I just increased prominence transmission by 25%. A fixed 6 degree tilt on the chroma et402.15x filter is absolutely the perfect compliment for this entire system to function. No baader planetarium erf was used, just a kg3 in front of everyt...
