May 21 AR and Proms in H alpha
Hi Everyone.
Another opportunity to image the big AR and prominences. Spells of reasonably good morning seeing allowed me (finally) to capture some more detail in the proms. I had high hopes of imaging in CaK but a cloudless sky turned rapidly ugly.
Equipment used: Aries ERF, C8 Edge, Moonlite CHL focuser, ~4.4x Telecentric, Daystar QPE 0.6A, ~0.7x FR, Point Grey USB3 Grasshopper IMX174 2.8Mpx CMOS
Cheers.
Peter

Terrific details when viewed in full resolution! This looks like you had really good seeing! What was the exposure time?

Re: May 21 AR and Proms in H alpha
Thanks everyone!
Frank, I was pretty lax about recording my camera settings ...bad scientific form for sure! I think I pushed the exposure time to about 8ms for the proms (full gain on the camera!). Exposure of around 5ms for the surface image.
Cheers.
