This is how i objective

On a less serious note.

It is hard to get good objectives, you have a narrative campaign, or you're just trying to get into the overall mood of your match, and you want a good objective marker to tie into the the spirit of "your guys"?

It might be just me, but i'm pretty happy with the way these markers worked out.

The first one is simply a plastic frame that we cut up with pliers, and then glue gunned onto some architectural construction foam, then i took the banner from the terminatour librarians back (overall i'm not that fond of the carrying of coat of arms on my models, they break of easily, and the detail is FAR beyond my skill to execute decently) and painted gold twice over.

The second one is more or less the same, except that i used a spare part leftover from the Dark angels Veterans sprue. 

Both of them have served with distinction in a campaign where the Dark angels where trying to locate their hallowed relics in the face of a tau expansion. Just small touched like the implication of a chapters specific involvement tends to help with the immersion when playing. 

The third one is probably my best one to date. It still needs sprucing up and "The relic" that is going to be placed on top. But all in all it feels pretty solid, these kinds of objectives are easy to do,fast to do and are easily customized to your needs. Just my reccommendation.
