Takes a bit of sleuthing to find the right parts, but if you have a 2" b-ccd filter you can just attach it to a nosepiece on an extension and slide the lunt filter into that extension. IF i am not mistaken, the back end of the lunt assembly is a standard T-thread, so you can disconnect it and adapt it to something like a baader planetarium barlow.

Mark your calendar "the sky WILL be clear on this day" and you can in effect use the law of attraction to work in your favor for at least one picture

Merlin: your settings have killed the limb He's captured a delicate spicule layer in that calcium image.

To colorize you gotta convert the image to RGB first, If you are using gimp just open up the levels adjuster and individually change red channel green channel and blue channel. See attached photos.

Finally have some very clear imaging conditions! 13 frame preview, i captured nearly 700 videos today of this at 400 or 500 frames per second. Sony 720-520um camera. modified meade shorty barlow operating at about 2.75x

The shape is definitely interesting, not quite a sphere as expected. . Could be a bundle of them, but it was pretty window so i would expected them to have separated a bit (maybe wrapped ina bag?). I can clearly see a very long string much longer than you would see on a children's balloon, however there is no payload attached so it maybe is just a party balloon because it was mothers day? <edit> a google search for square mylar balloon comes back with some similar results. It is almost certainly a square party balloon. Perhaps it had a payload that was dropped off? A quick google search reveals a government surveillance balloon with a similar shape, https://www.wired.com/story/giant-surveillance-balloons-are-lurking-at-the-edge-of-space/

Large file nearly 100 megs, about 800 frames.

Fighting some clouds right now, and trying to get another capture with consistent exposure.

i would not bother with double stacking such a small telescope with a second etalon, you are best to hold off and just save for a bigger scope. More aperture is more valuable than a double stack these days, because the double stack filters just are not made to the same standards they were 8 years ago when everyone was super buzzed about the h-alpha scopes. Double stack filters are more or less, "rejected" filters that are always off band.

very cool, as long as it works and you get pictures out of it ; mission accomplished.

still processing the high rez stuff, so until then enjoy this preview!

I would like to opt a new classification, called "plage region" This area appears dull in h-alpha and a calcium filter is essential to see it resolved. Thus a new classification of surface detail should be encouraged for these plage areas.

darker setting captured about 40 mins after the above image.

very nice; calcium processing is interesting. Depending on exposure time and gamma settings you can capture three distinct; separate layers of the surface. I think its a bit different than offband tuning with h-alpha, because you dont actually have to detune your filter, and if you hit the right capture setting you start seeing flux tubes and islands of spicules. Same filter, vastly different appearance. Entirely based on capture settings. The entire surface has spicule islands on the right. The left it just looks like granulation.

great shots Martin!

#5 is the winner!

welcome to the jungle

a beautiful region indeed

veery cool
