And then there was a GPC

[Rusted]

In my quest to become a real solar imager I have added a Baader 1:1.25 GPC to my 6" f/8 PST mods.

This morning [Sunday 27th] before it started raining  I captured some videos with and without the GPC.

Here's the result of a couple of swift bits of processing: The image scale is the clue to whether the GPC was present.

Always good to experiment. are you taking flats ?

Thanks Dave.

Not yet. Now I have the license from SharpCap I could give flats a try to clean the debris from my images.
I just need a simple [enough] guide to taking flats. Then I can be let loose on a startled world.

I use Firecapture and take flats using a bit of cling film stretched over the objective, then load them into AS3 for processing, well I do when I remember to take them 😂

Thanks Dave.

Do I continue pointing at the sun to capture flats?
Given my tendency to fire starting...
Same settings as for video capture?

Yes I leave it tracking at same settings, never managed to set fire to the cling film, perhaps it's fire retardant ?

What about using baking paper?

Needs to be translucent, I've  used those little plastic bags you get in UK supermarkets to put veg, in.

Thanks Dave. I was joking about baking paper on the "fire-starter" theme.

I have a very hot cone of light out in front of my 6" objective reflected back out by the internal filter.

I shall just have to experiment to see what is feasible. "Translucent" might transmit enough heat and light to survive.

Very nicely done.
