AR3107 and AR3105 comparison 25 September 2022

This morning through thin high cloud we imaged AR3107 and AR3105 in white light and Ha both single stacked and double stacked. There is a large number of sun spots in these two interesting regions. The double stacked set up is only new and still experimental. We think there is potential to do better than this image. Also thrown in is a white light of AR 3110.

White light images taken with 6" SCT, 1.8x barlow, ASI178MM and 540nm filter.
Single stacked Ha image taken with 72ED, Solar Scout Quark and ASI178MM.
Double stacked Ha image taken with 72ED, Solar Scout Quark, Lunt 40mm etalon and ASI178MM.
