C-2022 E3 (ZTF), LRGB

[Yawning Angel]

Early hours of this morning for a crack at Comet C-2022 E3 (ZTF), 15 x 60 sec for LRG & B.

Acquisition in NINA, using the Orbitals plugin for the location and changing the 'Sequence Mode" to 'Loop' rather than the default 'One after another'.  Library flats and darks

asi1600mm + APM 107/700. Processed in PixInsight:

• Initially just stacked the data as normal, ending up with a 4 mono starscapes and comet-ish smear
• LRGB combine and tidy up of the stars, stretch and then StarXterminator, keeping just the stars image
• CometAlignment on the registered images, output to a folder
• ImageIntergration on the LRGB groups, with some aggressive rejection
• LRGB combine on the comet images, stretch and background clean-up (a slight detour into PS for that)
• PixelMath the stars back in

Nice shot! I've been battling clouds non-stop over the past month so I haven't gotten a great look at it yet, but maybe tonight 🤞

Can you clarify what you mean by this? The only setting I see anywhere related to Orbitals is the refresh interval. I've tried to use the plug-in on two occasions and the comet has ended up in-frame but pretty far off to the side. Would you mind sharing a screenshot of your sequence entry?

These are 2 separate things:

The Orbitals plugin, remember to update the data :

The hit frame, and from the framing screen slew and centre then update your sequence

The loop option is on the sequence tab, and just makes it do L-R-G-B-L-R-G-B-L-R-G-B etc rather than L-L-L-R-R-R-G-G-G-B-B-B

I hope this helps

The data is here, if anyone wants some to play with : Google Drive Link

Thanks for the response - I didn't realize you were using the Basic Sequencer, so that makes sense. Looks like when I imaged on 1/24, I hadn't refreshed my data since 1/18 so that probably explains why it was off-center.
