Hi all,
Christian Sasse, astronomer in charge at iTelescope.net shared this beautiful data set of Comet Leonard. It was shot with T56 from Australia.
It is RGB filter data and processing was very easy in APP 1.083.
I processed it in multi-channel mode, and the comet registration worked perfectly on the bright comet nucleus.
It gave me 4 integrations:
- Red
- Green
- Blue
- and I integrated all channels into another stack, so that is RGB combined to get a Luminance stack.
With the RGB Combine Tool, I used formula LRGB2. Then removed the gradients with the Remove Light Pollution Tool and finally made a very nice stretch with APP's preview filter 🙂 Please click on the image to see the full resolution image.
Hope you like it!

Really great picture, Mabula! Such detail. Appreciate the overview on the workflow. I used a more direct stacking workflow and then ran post-processing through Adobe Photoshop and Lightroom a few weeks back. This is a wide field view of C/2021 A1 from Suburban Maryland, just north of Washington DC taken using a RedCat 51 and a ASI2600MC-Pro. About 30 minutes of total integration time, 30 seconds per exposure.
~Clear skies!
Thanks @cpear004 and you are most welcome !
Thanks for sharing your result as well, it is very nice 🙂

I had a few Comet Leonard encounters - including one where I have stacked with the Comet Registration process from 1.083
Herein attached is One without the Comet Stacking (shows elongated Nucleus) - Slightly different processing in each, as the Comet registration also seemed to change the end result in overall colour data.
These were from Green Point, Brighton, Vic - travelled down there on the night from our place in Ringwood East specifically to nab the beasty
Hi,
is it now possible to register on the comet AND the stars at the same time? So that in the finished stack the comet and the stars are sharp.
@daniel_n Yes, it is on the TODO list for a future version but not for APP 2.0.0.
