Hello! A7s to do astronomical reform, only remove the IR lens, OK? In your video, just remove the first mirror reflecting red light, OK? The lens attached to the CMOS is a low-pass lens (he just removed the moire, right), it doesn't have to be removed, does it? I only removed the mirror reflecting red light, and took photos and videos of the emission nebula M8. However, I found that there was no difference between it and the original one. The red did not change much at all. Do you know why? thank you
Did you remove the shims or not? It was not clear in the end. I also converted my camera and leaved the shims inside, which was a big mistake, because of this I don't have infinity focus so I have to take it apart again and move the sensor closer to the lens.

thanks for this video you made, did the same for my own a7s, works pretty well now
How's the image after filter removal?

hi, did you finally removed the shims ? does it works ? thanks
I hope you mount the CCD on a big heatsink and not in a camera - but in a custom made box
How to clean sensor glass before gluing window?
Full specrum for Astronomy??
i do not know much about the filter and stuff associated with that sensor, but isn't there also the peizo element for clean off the dirt though?

That's the part you're referring to.
Don't put it back in! It also blocks IR & UV which you certainly don't want.
probably better sell this A7s and use the money toward buying a cooled CCD
Nice video ! Have you made some real night scene shoots please ??? Thanks !
hi, could i re-upload your video? just wanna add some background track, and i think this is really nice as well.
Ahoj, ako si prosim Ta uvolnil viewfinder 24:40? Je to tam strihnute a nevidiet to. Inak diky, ye si to cele natocil :)
Bold.
I hope I have a camera to practice :))
why would you do this
Israel Villarreal he is doing it to use for astrophotography...
