MiniSHG and DIY CaK results 16th Sept 2021

[Merlin66]

The usual CaK DIY image - the AR is almost gone and the disk is quiet.

The MiniSHG - some interesting results.
1. The "usual" result of a 9sec scan tuned to the centre of Ha wavelength

2. Selecting a wavelength about 0.4A into the Ha wings

3. Selecting the Prom image from the scan (may be a little overexposed??!)

All these results from a single 9sec scan. (much shorter than the conventional CaK exposure!!)

4. The results of a 4 image stack (AS3!) I have to say, very impressive! Compare this with #1 above.

I think a stack of even more images would give a excellent result.

Onwards and Upwards

Enjoy..

That last image has almost a 3D "alive" feel to it 👍🏾 (almost as if its inviting you to hold it in your hands & feel the texture...)

[Merlin66]

Yeah, I agree!

Notice the filaproms.....

I did a colourised version - just for fun.

Enjoy

Same here (well apart from holding it in my hands!), the last image has a really nice feeling of depth.

Thanks for the views, I can skip the vitamin D tablet today.

how many hours would it take to produce a 100 frame full disc timelapse

[Merlin66]

Apollo,

Each scan takes only 9sec.

If your SSD drive is big enough you could record 6 images/ minute or 360 per hour.

The SER video file is about 4gb and each image is roughly 2500 x 2500 pixel and 12mb.

Nice sharp images, hopefully some new activity is around the corner.
