First time imaging the sun

[Nikolas (Nik)]

I've finally modified my eq2 mount and decided to give solar observing a go with my rarely if every used coronado solar scope (gonna sell it if anyone wants it)
Apart from reigniting my headache from the glare I managed to try my hand at solar photography with the asi224 and 174
There was high level cloud but managed to snag a few sunspots and prominences, Not sure about the red halo
Any tips would be greatly appreciated

The hot spots are difficult to avoid in PST's when doing full disk images. Doing a flat field can help. Whilst colour video cameras can be used, mono cameras do a better job. I suspect the spicule layer is where your camera is particularly sensitive and when you stretched the image (non linear) to bring up prominences, the red halo became even more prominent.

Thanks Ted, that makes sense, complete novice in solar but it's not for me it gives me migraines.
Cheers

Ted,
I think Nik is using an external SM40 etalon, which has little "hot spot" effects.
IMHO Coronado made a great mistake when they went to the internal " Rich View" design, the external etalon is much much better.

Thanks Ken, oops...I just noticed Nik's equipment list and the SM40 not PST.
