That doesn't sound quite right!
In any case, not very deep, but a little long at ~1480mm. Only 2m exposures taken tonight in Ha (90 mins total) + 30mins of RGB from RASA session a few weeks ago. Pretty quick and dirty!
The trade-off are the colour halos on the RGB layer which has to be upsampled to match the Ha resolution during registration. But it's a small sacrifice to turn around an image like this with only 2 hours total integration. The lepus focal reducer causes some minor coma on one edge.
