Re: Sony IMX253 mono cameras
Mark's advice that "a SSD is a must as is RAM which is easy to upgrade. Consider a portable SSD drive that you can save direct to will make it easier for the PC." A word of caution: I've observed that connecting a USB camera together with an external USB drive (both USB 2.0) and recording directly ...

Re: Sony IMX253 mono cameras
As for USB 3.0, I began using my current Chameleon 3/ICX445 in 2015 with a 2011 HP ProBook, for which I got the i-tec EX1USB3 adapter. It has one of the chipsets recommended by PGR (NEC/Renesas μPD720202) and worked w/out problems under Windows and Linux.

First CaK results
I'm learning how to use my newly acquired Lunt CaK module (straight-through, B600). So far tried with my 90/660 mm Celestron achromat and with the GSO RC8 (with Aries ERF). Unfortunately there was literally nothing on the Sun at the time of capture, but the image quality seems promising (all from th...

Mars rotation
My GSO RC8 does OK also in planetary imaging:
23 minutes, 3-minute intervals, PGR Chameleon 3 mono (ICX445) + Baader Red 610 nm long-pass filter, @f/16.
The small bulge in the upper right is the Olympus Mons.

Re: PST Mod and TEC140
As I understand, Merlin meant the configuration without any Barlows; in that case, the f/7 beam from your 140 mm, f = 980 mm 'scope would be only used by the PST as an f/10 beam (because of clipping), having f = 980 mm and D eff. = 98 mm.

Re: Solar granulation with C14HD full aperture
Excellent images! Out of interest, where did you get the solar film? I needed some ND 3.8 recently, but the biggest I saw were A4 sheets. WoW! I think that is the biggest scope I have ever seen an amateur put to solar use. I think Dr. Hänssgen wins with his 42" Dobsonian ;) http://www.cruxis.com/sco...

That's a great animation.

Try ImPPG, it has the same function (Tools/Align image sequence...), and more besides.

Re: Lunt LS50THa modification to 200 mm aperture
After a short (ahem) break I'm continuing with the mod. I had nice sunny weather this weekend and did some further tests. I was afraid I may experience thermal issues like Marty with his Newtonian — since I also don't have a corrector plate nor a front meniscus (if that's what makes the difference);...

Re: What is the definition of, "Hi Resolution"
In my post by "resolution" I meant: smallest resolvable features assuming optimal sampling rate (i.e., Barlow + pixel size combination) and very good seeing.

Re: What is the definition of, "Hi Resolution"
high res to one person is higher than what they have ever imaged before :) Right, something along these lines. A few years ago I considered all those PST and Lunt 35-60 images "low-res", and anything from 80 mm up "hi-res". Since having advanced to a 90 mm Hα setup myself I now consider it "mid-res...

Lunt CaK module vs. refractor baffles
I'm thinking of dipping my toes into CaK imaging using a Lunt CaK diagonal. One of the telescopes used would be my Celestron 90/660 mm achromat, without an additional ERF. It has a few internal baffles (blackened) - should I be concerned? - when pointing the 'frac at the solar limb, the light cone c...

Re: C11 HA + CAK Imaging - Got rid of reflected light!!
Got it, thank you. Makes sense — the reflection was off-center, so if you move the camera further back, it finally moves outside the FOV. (And the magnification stays the same, because PM is telecentric.) Good to know, I was also considering PM 2.5x for a configuration I have a mind.

So what's changed in the setup? The PowerMate is now after the diagonal instead of before?

Re: Solar Animation Tutorial (June 2020)
I haven't seen this one before, but yes, it looks like the cubic interpolation shader isn't executing exactly how it should on your setup. I'm guessing the saved processed images look the same though for both back ends? Could you send me the stack and ImPPG settings file so I can check on my system?
