20260304 NGC 1893 - Pillar mount connection changed - Comparing S30 and 533mc pro

I change the way the mount is connected to the pillar, should be more stable and consistent now.  That quick release bracket was removed.

Canon 200mm again, with Antlia quad band filter tonight.  The Antlia filter is creating bloating stars.

Recalibrated the guiding since it's quite erratic.

I then pulled out my Seestar S30 to point at NGC 1893 as well, the field of view is much narrower.  I shall compare them side by side later.

First up is taken by my 533mc pro, 300s exposure x 24 (two hours):

It should win hands down, better sensor, better optics and longer exposure.

Next up is taken by my Seestar 30, 30s exposure x 300 (1.5 hours):

The field of view is narrower, smaller sensor, smaller pixel, non-cooled, shorter exposures and shorter total exposure.  However, the result is still very respectable.
