Bart,
I should have said my ol' ACER didn't have USB3 ports.......
Yes, I forgot that too. USB3 is crucial!
And I should have said that I swapped the original 256 SSD for a bigger one. Everytime the free disk space was lower than 100 the fps dropped significantly.

Re: I need a laptop that matches the speed of ZWO ASI174

There is no need for an expensive gaming machine. I use an Acer Aspire V3-371-39C5. Swapped the drive for a fast SSD and dropped in extra RAM memory. Maximum fps is no problem.

Re: AR12738 - CaH

33ms, that is surprisingly long. I did not think it was possible to get sharp images with such a long exposure time. Have to try that myself.

Hello Bart,
I prefer the one without drizzle. Inverse granulation is lost in the drizzle version.
You are right Christian, I did not notice it before you mentioned it. Should try and reprocess the drizzled version. Thanks! Bart.

More of AR2738, 14042019. SC and H-alpha

Seeing was not good enough for the shorter wavelengths. Solar continuum was difficult, H-alpha was better. First image is with the 150mm f/8 Skywatcher achromat.

Super image despite your session being cut short. Are you using the Skywatcher Evostar scope? If so how do you think it compares with other scopes you have used for Cak?
Thanks guys!
No, it is an old Celestron 100mm F/9 ED. It is way better than the 150mm f/8 Skywatcher achromat.

Re: Help tweak this PST + SM40II Double Stack?

Top of the prism should be parallel to the top of the black box. Just open it up, it is pretty straightforward.

Re: Help tweak this PST + SM40II Double Stack?

Did you check the pentaprism? Is it aligned properly? Visual it is a bit less crucial than when imaging.

Re: Anybody Using The Baader TZ3?

Hi Mark,
I am using one for CaK. Still more to experiment before I can say if it is really beneficial for CaK. The TZ-3 itself is a nice piece of kit. Does not weigh much, about 200 grams. CS! Bart.

They came out well Bart. What do you think an ideal focal ratio with this scope and camera setup would be?
Thanks Franco and Mark!
Hard to say Mark, but I think somewhere between f/14 and f/16.

That looks beautiful Stu! And interesting to compare your CaK image with mine. Even the image scale is almost the same.

AR2738 in CaK

The idea for today was to image the sun in 5 wavelengths: CaK K-Line Solar Continuum White Light H-alpha But I only succeeded in taking one (1) AVI when the clouds rolled in.... So here is AR2738 in CaK. 100mm ED f/9 _ nosepiece of Lunt filter _ single K-line _ 2 PST#1 filters _ ASI290MM https://liv...

Thread of Coronado diagonal

Hi everyone,
Does anybody know the thread size of the (black) part of the coronado diagonal? So the part where the blocking filter is mounted. I would like to ditch the diagonal and use it as a straight through.
Thanks!
Bart.

Nice! And beautiful HR CaK! Did you use LR and UM? I used Christian's advise to use only UM. 1,3 - 8. It works for me.

Re: CaK and H-alpha, 07042019, new AR

Thanks guys! I agree with you Frank about the second one. Saw that the mosaic was not perfectly round. Tried another program: https://www.microsoft.com/en-us/research/product/computational-photography-applications/image-composite-editor/ Freeware and very easy. Results were better than with Photoshop.
