The night Blitz is basically defined as later than the BoB itself, - BoB being from the channel skirmishes after Dunquerque untill the LW gave up daylight bombings, - some define it to a narrower dayframe as well.
BoB daylight ops from the British side go almost just to Spits and Hurricanes, but there were some Squadrons of Gladiators and I think Defiants showed up a time or two.
At night, Blenheims mostly. (600 sqn at Manston was in the nightfighting business)
From the Axis side, 109's were the common fighter with some 110's, then the mainstray of the bombers were He-111's, then the flying Pencil (Dornier), then the rarer but excellent Ju-88, and then Stukas, which were mostly active in the beginning.
Then once the Eyties showed up, but had a bad day, so.....
110's would do some low level bombings (Hit & run) with quite some success as well.
On the Britishg offensive side, there were Welliongtons, Blenheims, HP Hampdens and some more. Actually, Göbbels had his garden bombed by RAF in the times of BoB.
