Expect SpaceX will try to docked their ASDS early in the morning to have more daylight time to disembarked the F9 cores and transferring them to the transporter afterwards.

Looks like crew transfer is happening, look to bottom right of the booster you can just barely see GO Quest backed up behind OCISLY. #SpaceXFleet #SpaceX

Starlink Mission Ten comes to a close as OCISLY arrives at Port Canaveral with B1051.5. This is the second booster to have been recovered from five launches, including DM-1. Scorch has made this booster deep shades of grey with customary leg tan lines. #Starlink #SpaceXFleet

Looks like they're all prepped to lift Ms. Chief's fairing half.  Ms. Tree's half is still tarped and Ms. Tree has moved to make room for OCISLY. #SpaceXFleet #SpaceX

SpaceX's B1051.5 on board OCISLY made its way into port this morning. The booster has made five round trips now and will be returned to the hanger for refurbishment for its next mission. Its difficult to make out the logo on the sides at this point.   #NASA #SpaceX #Space

While Falcon 9 B1051 was being berthed, GO Ms Chief’s fairing half was being hoisted off her deck.

Thanks to @Kyle_M_Photo for shouting, “Fairing!” while I was busy yammering away with my fellow port stalkers. 😂

Falcon 9 fairing half with people for scale. Imagine piloting a ship to get under this as it parafoils down towards you. There is guidance involved, yes, but sometimes things don't go as planned and the Captain has to be ready for abort and scoop.

They are still working at the legs, but they haven't made too much progress that I can tell.  They're also doing a few things I've never seen done before like that panel in the center of the leg well is open.  #SpaceXFleet #SpaceX

Starlink V1.0 L4 - L8 all inserted into their coast phase at around 216km altitude. L1 - L3 however inserted at around 168km. Starlink V1.0 L9 marks a return to the earlier insertion altitude, at a slightly higher velocity, but with only 57 Starlink satellites on board.

Why? The 60 L3 satellites were deployed at an altitude of 302km, close to a circular orbit. The 57 L9 satellites were deployed at about 400km, also roughly circular, because that is the required orbit for the BlackSky rideshare satellites. Achieving this orbit required a small reduction in overall payload to 57 Starlink satellites.

Are you sure the orbit is the reason for reduction to 57 Starlinks?  The delta-V between 302 km circular and 400 km circular is about 56 m/s.  Getting rid of 2 starlinks (at 260 kg each), then adding 2 BlackSky (55 kg each) should increase second stage performance by about this amount using the usual assumptions (total payload about 15.6t, ISP=348, burnout mass=5.5t, including residuals), plus another 5 m/s from the first stage.
Aha - I see what I missed.   The above calculation estimates that the F9 could have inserted into the higher orbit with 58 satellites.  I think this is correct.  But SpaceX also needed to de-orbit the second stage from the higher orbit as well.  It's not much (about an extra 30 m/s is needed, and the stage is 4 times lighter after the payload is separated), but it's enough to require three Starlinks less, not two.
