A return to planetary with Venus

With the planets being morning objects and low to the horizon, it can be challenging to get a decent planetary image right now. I had the first clear morning in ages recently and whilst the seeing impact on the other planets I tried (Saturn, Mars & Jupiter) was pretty severe I had some moments of reasonable seeing for Venus.
I am really pleased with the purchase of the ZWO ASI 178MM and what it has done for my Venus imaging. My ASI 174MM is quite insensitive to UV and has large pixels (5.9 microns), where the ASI 178MM is ~ 4-5X as sensitive to UV and has much smaller pixels (2.4 microns). When imaging in UV a barlow will usually knock out most of the radiation, so imaging at Prime Focus is the preferred option. However, I had suffered with a poor image scale previously and a loss of detail. The 178MM has a much improved image scale of 0.13 arc secs per pixel and allows me to resolve detail down to perhaps 0.4 arc secs. That is a big improvement versus the 174MM which has an image scale of 0.3 arc secs per pixel and a resolution of closer to 1 arc sec.
I was also pleased to see good resolution of features with the 850nm BP filter.
I produced this false colour image following the IR (G) UV convention, but also showing the component images..

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
