Solar Sunspot Group AR2795 and AR2794 WL & Ha 27/12/2020

Post by Martin_S »

A perfect day in Brisbane this morning so I set up early, before the atmosphere started to boil. I managed to get some close ups that were close to the limit of my seeing.

Captured in SharpCap, stacked in AutoStakkert edited in Photoshop

White light captured with my 180 Mak ,ND3.8 solar film IR cut and solar continuum filter. ASI120mm camera

H-alpha captured with my Lunt DS 50/60 2x Barlow and ASI290 mm camera.

Very well done. The white light images are some of the better ones I’ve seen. Do you feel like your Mak is affected by tube currents? Have you done anything to mitigate them?

David, for night time work I let it cool, for solar I image early in the day before everything heats up. I also try to get as short exposure's as possible when imaging. My solar filter is made from plywood and is wide enough to keep the suns rays off the tube. I would not even consider imaging with a Mak that is not close to the ambient temperature.
