September 19, 2020: 3.5 hours more data on M27

Got 3.5 more hours of data on M27 last night, and the GP mount was tracking like never before. Just stacking these 12840 s of data from the Meade SN6, with ASI183MC and Optolong L-eNhance filter got me this

M27-12840.0s-MSC_1_3.0_none-x_1.0_LZ3-NS-full-qua-add-sc_BWMV_nor-AAD-RE-MBB10-StC2.thumb.jpg.7326065654bfed482b5487f7d614e78c.jpg

Combining this with the previous 5 hours of data from the same combo got me this:

M27-30990.0s-NR-x_1.0_LZ3-NS-ref-qua-add-sc_BWMV_nor-AAD-RE-MBB10-StC2.thumb.jpg.46eeed54aa4cd9b4b7ea4730017395ee.jpg

And mixing this with just under 2 h of data with the 80mm and same camera and filter gets me this:

M27-37650.0s-NR-x_1.0_LZ3-NS-ref-qua-add-sc_BWMV_nor-AAD-RE-MBB10-StC2.thumb.jpg.23a893404c05fb1f24f974b8425b0bd7.jpg

Hopefully, I can add more in the coming two nights, to get even more signal in the outer shells. I might also want to do some unsharp masking to prevent blowing out the centre
