made a sheet for each version

Chris B, while commenting in the forum on the situation with the Deep-Sky Gems list, found in the RASC Observer's Handbook... he hinted at that separate lists should be made.

Oh boy.

So I made them!

And, curiously, seeing them all laid out beside each other, tabs in the Excel workbook, revealed the extent of the changes.

There's a version for 2008, 2009, 2013, 2020, 2021, and 2023.

The original and then 5 revisions!

That ain't right.

OK, hold up. To be fair, the DSG observing certificate program was launched a couple of years after the list first appeared in the handbook. I believe it was unleashed in 2010. So, in theory, people started working from a list after the first revision.

And then no changes happened until 2013.

It's really 4 revisions, I believe, that might affect RASC members in the middle of their observing campaigns. 

Still, the frequency of change sure appears to be accelerating! Some nasty dark energy there...

And the last one, for the 2023 edition, was completely unnecessary!

That was upsetting.

Hopefully—hopefully!—in all of this, we can clarify things for members. The Observing Committee needs to assure members they are not going to need to go back and do more work...

We're ramping up to publish our findings. Then we can breathe easy.
