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

I use Irfanview (freeware) to colourise my solar images obtained from FireCapture/ AS3!/Imppg.
Image tab/ Color Corrections/
R/G/B/Brightness/ Contrast settings:
WL = 75/38/22/0/0
CaK = 25/-5/105/8/-2
Ha(surface) = 84/-14/-114/9/14
WL and CaK setting shown.
You can play around to find a combination you like.
(you can also remove the background using Replace Color)
Merlin: your settings have killed the limb He's captured a delicate spicule layer in that calcium image.

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

Fascinating! I wonder what kind of balloon it is.
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/

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!

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.

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.
