Excellent, good to see some mod images. Great results, for a snip compared with the price of commercial scopes of similiar apertures.
Honestly, commercial scopes are way over priced. $10,000 for a telescope is just stupid, i dont care who made it, what its made of, or where it came from. All Modern telescopes are made on push a button and its done cnc milling robots. .
Literally upload an image of the optical schematic and push print, then drink beer. All the humans do now is push a button and clean up the robot poo. (metal and glass dust)

tried some h-alpha today. very old pst mod on a 127mm x 1200mm with a 1.7angstrom blocking filter and for some reason a baader planetarium B-ccd filter working as an ERF LOL!

i think the sunspot rotation is the most impressive part of this entire capture, i dont think another amateur has captured this affect ever.
You may be the first, and its worth investigating. Ive never seen them rotate in SDO captures before and ive watched them for 10 years.

that second image is killer! looks like the dashboard on my car

This isn't really a surprise. Most filters have some out of band transmission (this is usually referenced as their optical density (OD) value). Even the best filters transmit some light out of the desired passband even if it is a tiny fraction of a percent. If you put the filter in front of a very bright source then you will inevitably see the leakage (a fraction of a high luminosity can still be a high value etc). Even Baader don't claim a perfect filter (you can see some leakage in their filter profiles). Nevertheless for RGB filters you use these primarily to obtain colour data of a broad ban image so some limited leakage can be OK as it isn't the dominant component. Also you can expose on G2V stars to get a 'correct' colour balance (for our eyes) anyway which would remove any leakage impacts.
I understand that. however this is a bigger mistake than it would seem.
The transmission graph on their website reveals zero leakage in the h-alpha range so it is a bit unusual; almost as if this is intentional. You can see the leaks all over the place as you say; but this is pretty huge and how could they miss h-alpha transmission with this large of a peak? Especially for being "the best of the best".

So yea. I added a baader planetarium hydrogen alpha filter to my baader planetarium blue ccd filter and bada boom. a ton of h-alpha light out of my blue filter!
How embarrassing, yet extraordinarily remarkable that nobody else noticed this.

very nice

Some interesting activity on the center of the solar disk.

Still processing more frames so here is a teaser. Calcium light as always,

these active regions are awesome, I am glad you had the chance to observe them. Clouds and haze are so persistent these days.

just distortion from atmosphere and processing, you will never see spicules with astrosolar film.
You can however mask your objective with a Bg25 piece of glass stacked with Ug11 glass and the baader filter on the camera to achieve very wild results. Be warned however, this can get be dangerous if you are not careful and it takes some skill to do this properly.

You can find the glass filters on ebay.

looks like you are having some fun

Looks great!
What program do you use for stacking?
I am using autostakkert 3.14 (x64)

This AR cropped up next to 2824 this morning and i raced to grab a sample of it before the clouds rolled it. Wish i had more to share, this region is loaded with Shear force and it is pretty obnoxious looking.

here is a different processing type, i boosted exposure a bit to reveal the umbra a bit more . It shows some out gassing!

That looks really impressive!
Hands down no contest, the celestron luminos 2.5x barlow is the best optics upgrade i have had the pleasurer to use. Way better than a televue powermate, no doubt about it. I highly recommend anybody that is looking for a boost to pick one up.
Super high quality piece of hardware, and I would give it a perfect 5 stars out of 5 stars if i could.

I am very excited to present the highest resolution i have been able to capture yet with my skybender calcium filter, and this was though a terrible sky! Explore scientific 127mm x 1200mm + celestron luminos 2.5x barlow + basler aca720-520um camera operating at 400 frames per second.

The cloud thing has taken over the world of solar imaging, I have noticed that even gong feed is spewing out the cloud phenomena now on places that usually never had them; thats why the sites were chosen for those scopes
It could be a global pattern change for sure, or some jerk playing with the weather using cloud seed techniques. (i am betting on the jerk phenomena, coughbillgatescough) https://www.forbes.com/sites/arielcohen/2021/01/11/bill-gates-backed-climate-solution-gains-traction-but-concerns-linger/?sh=73c2a642793b
these jerks come out and say they want to do this stuff, then back track and say "oh we are not really going to try this it was just a theory on a computer" , then the jerk actually does the experiments and hide them with non-disclosure laws.
Just look at the gong page, all of them are washed out. Back. in 2019 gong almost never had a cloud out delay.

You can do that in CaK? Looks great indeed!
Persistence is key, and they are only going to get bigger and better . I ditched all my h-alpha in favor of calcium long long ago.
Its a shame you were not around when I was handing out free skybender's. I would have mailed you one.
Kudos !
