ND I have the original serial number from the black box.

Good news for you beauty nerds. I found the tuning ring so the scuff marks on the ETALON are covered. I will ship everything in the initial post except the self centering adapter and the glass path and BF5.

Here are the photos of the ETALON after I have removed the gold tubes. The ETALON looks clean but I want to make sure you know you will not win beauty awards with your mod. The ETALON has some teeth marks on the surface but that does not impact performance. I will ship with both gold tube "extension...

Ouch! I just found these offers so I will contact you in order. So sorry I had not gotten the messages.

BTW, the BF5 is sold and the gold tubes are removed and the self-centering adapter is now repurposed.


Stay tuned,
Jack

Great and interesting explanation Simon.

I never considered binning the sun since I equate binning with decreasing exposure on do objects.

Mark and Rainier, It's the physics and the math which confuses me so I get lost in marketing hype. I appreciate the insight. If the primary difference is for visual then I can consider I rarely am visual. If my camera limits me then that's another issue. I neli3ve it was you , Mark, who turned me on...

I want higher mag for my DSO, Lunar and H-Alpha work (and whitelight too).

I'm parting out my PST Stage 2 Mod. $99 gets you my Coronado (pre-Meade) Etalon #95471 (and the attractive portion of the original gold tube which I adhered to the Etalon as a nosepiece into a 2" focuser). The Glasspath is already sold. If you'd like the extension tube you are welcome to it (it also...

camera is alllllll clean

Thanks, all! I"m convinced! Sadly my first spin was less than enthralling, but I'll keep at it. I have the Baader Photo Solar film (3.8) and the Solar Continuum. I'll bet tomorrow it will pop into amazing! I did see the one larger and 3 smaller sunspots. Oh and of course, my camera dropped out of th...

My Debbie gave me a Solar Continuum filter and Photo Solar Film for Christmas.

Do I need the 1.25" or 2" filter? I can utilize either format, but don't want to vignette in white light imaging.

Thanks,

I add a focal reducer on my refractor rigs up at the camera successfully to widen the field.

Crystal clear on all features.

Yesterday another good example...several days came all bunched up.

And I am happy to help test.

I receive updates to forums and watched threads. But recently delivery has been spotty and I can go for several days without an email.

I’d be thrilled with that image!

Great presentation

NOTE 1/2/2021: I'm parting this unit out but leaving the ad up for reference. I've created a new ad for the components. :) Jack *********************************************************** I'm relisting my PST Stage 2 Mod which works on both an f6.5 and f10 system. I'm pleased with the results but am...

Glorious!!!

After years, I finally got my PST Stage 2 Mod to work and it's on my f6.5 scope (just in time to sell the Mod). I've created a <5min video comparing the PST Mod with my Quark. Both are using the 152mm f6/5 achromat with some sample images below. https://youtu.be/6V3GPGZm4ns Thumbnail.jpg WITH PST MO...

Really sharp!

Nice close up!

Beyond beautiful.
