Re: PST Mod C11

Ahhh, understand. There is no obvious way to do this, maybe a tilt tuner on the camera nosepeice and try and orientate so it is looking off axis into the direction of the sweetspot offset, but, I don't know if this would work and it would be a faff. I bet if you look on the exit side of the etalon, ...

Re: Eyepiece, and focuser for camera

Hiya. Regards eyepeices, i've always found the plossls work best, indeed I use Televue, my favourite is the 15mm. I'm assuming you have the Bf3400 blocking filter? A 41mm panoptic is only going to give just over 20x magnification with the Lunt152, and is going to give a very small disk relative to t...

No probs with the blocker.

Whether the DS etalon will work as a SS is a different matter, but, try it...

Re: PST Mod C11

You can set the position of the ROI manually in Firecapture by click and dragging the red box. It shouldn't matter the orientation of the offset sweetspot, you can just drag the box to fit.

Re: Sun part 2 Friday 31st July WL & CaK

Mark, it is a Dell Precision 17 inch laptop with 4 K screen. It cannot display black at all even in video or photograph, it condenses it to solid blocks of greys. In full colour it is wonderful, for black it is hideous. I see no way round the problem. Trying to capture a prominence is like looking ...

Cool, we have another one coming. A wonder whether it will be cycle 24 or 25?
It's another in high latitudes, it's 25.

Ha Views - 3rd August

Mondays weather did exactly the same as Sundays weather did for me - crystal clear blue skies first thing before the instability kicked in and the sky clouded. Given the good seeing first thing I decided to try the HaT out and see if it would hold up; it just about did and for a change I got some us...

Re: Calcium Sunday 2nd August

Hi Raf, have you had any experience with the Technosky 152/8 fpl-51 triplet? there's one here in the UK going at a good price... yes but not for solar, I looked into the scope of a friend of mine, cant' tell nothing about H-alpha or calcium. However I wouldn't consider it unless you can look at the...

Re: Sun part 2 Friday 31st July WL & CaK

Lovely images, ooodles of detail in the CaK closeups.

Have you tried different display settings with your new monitor? The posterisation sounds like it's running on fewer bits than it should be... Do you have a new PC and running a secondary 4k monitor?

Thanks everyone for the kind words, going to get out observing in the next hour or so when the sun is high enough in the sky. Cristal clear images, Mark, with superb definition. Long focus achromats have very low spherochromatism and are perfect for CaK. More difficult is to find suitable seeing con...
