The comet from Ipswich on 10/05/2024 at 18:30. Stack of 30 x 15 seconds images using the Dwarf 2. No processing. The field of view is 3 degrees.

Another good result for the record.
I've been quite distant from Astro for a few yrs now, but went to the local meet recently and saw some these new little 'Smart Scopes about, interesting times indeed, that said I googled the Dwarf 2 and see it's a 100mm F/L, is that correct ?
Im now wonder why the field-of-view of your image appears quite small, unless Im missing something, have you cropped the resulting image after processing, or has the Dwarf 2 some Pre-Sets when capturing. like optical zoom or Region of Interest or scaling effect adjustments ?
Cheers..

The Dwarf II does have a 100mm F/L.
The field of view of the image is about 3 x 2 degrees, which I think is quite reasonable.
The image is not cropped, but resized to 1000 x 563 from 3840 x 2160 pixels and compressed to get it down to the 200K image limit.

Can you tell me why you think the FoV is small and compared to what?

Just seems like the comet is taking up a fair bit of space in the image,
Ive just done a Stellarium simulation of your field of view and its stating 2 degrees, Id assume in horizontal, but no drama if 3 deg...
I have simulated my 135mm field and stellarium stating 6.8 degrees..
That said, all i can guess is that your chip is really small with super tiny pixels unless im missing something,,,
With all due respect :)
