Hi Callum,

Another stunning image (from London!) but can I ask the same question again...how big is the field of view?

It would be really useful if anyone submitting images of deep sky objects could put a scale on them.  And for the more obscure or less well known objects a location and/or catalogue designation, i.e. NGC, IC etc.

Thanks, Mike.

Hi Mike - Have added this in the exposure settings and added the catalogue ID.

Thanks Callum.  Good idea to put details in the "About this observation" box,
