74. M42 (another wide field)

Taken with Vixen FL55SS (Baby VSD) + flattener + LPS + 100Da @PTC in 2018 @315mm F5.7
20x120s @iso1600, autoguided with Vixen AP mount
Stacked in DSS with darks calibrated only
Processed in PI and PS

That is a re-processed one. If interested, you may compare this one with image #72. Because they look a little bit similar, both image scale and resolution, I think.

75. Horse Head

Taken with VSD + LPS + 40Da @TMS in 2014 @380mm F3.8
3x180s @iso800, autoguided with Vixen GP2 photoguider in RA direction only
Stacked in DSS with darks calibrated only
Processed in PI and PS

The transparency at that night was very high. After shooting M42, only 3 lights of this object could be captured before the cloud came.

VSD + LPS + 40Da @TMS in 2014 @380mm F3.8
Stacked in DSS with darks and flats calibrated
Auto stretch in PI

Thanks to the very high transparency of the sky at that night. To me, that is the best nebulosity around M42 image obtained from TMS even up to now.
