Image Database

[Alan Thomas]

I have recently finished posting images of the 15 Palomar globular clusters. At present ‘Palomar’ does not register as a search item. Would it be possible to enable this?

Hi Alan,

Thanks for posting these images – and well done on completing your observing project!

Currently I seem to release updates to the image gallery object database roughly once per year – with the exception of comets, which automatically get added when they first appear in the Comet Section archives. It’s about a year since I last added a bunch of extra deep sky catalogues, so it’s probably about time to think about a new update.

The criteria I generally use to decide which catalogues to add is to look through the list of untagged images, and see which catalogues are easily available for download from reliable online sources like CDS / Vizier.

As it happens, the Palomar catalogue is already my top priority for the next update.

It won’t happen right away, but perhaps by the end of the summer.

Best wishes,

Dominic

I would certainly love to see the Palomar clusters added to the catalogue, some interesting images from these difficult-at-times to get clusters.

I also support this, having imaged several of the Palomar GCs.

While on the subject of GCs it would be nice if one could tag extra-galactic GCs (for example, Mayall II) with both “globular cluster” (term not yet included in the dictionary) and the host galaxy “M31” (already present). Would make finding images of GCs much simpler.

Of course, the same approach would be helpful for other classes of objects, such as “double star” and “planetary nebula”.

Thank you very much, Dominic.

I cannot really claim much credit for obtaining these images: I used the OU’s robotic telescopes at Tenerife, and they do most of the work for me.
