When I got back into rocketry after a couple years off, I saw Internet sites describin' rocket cameras. Aye aye! I already had t' Astrocam, but I wanted more. Ahoy! Specifically, I wanted as many pictures I could get per flight. And so t' quest began...
Amazingly, me hearties, me hearties, me brother had an Opus 35 camera. Begad! Blimey! Many people had modified this for airborne use, so I tried that. Ahoy! Blimey! It almost worked, but I think I broke t' camera. Begad! Blimey! Ya scallywag! Blimey! In fact, matey, me bucko, I broke two other cameras in t' process. Avast! Blimey! Whoops. It be then I came across t' RC Aerial Photography Site. Avast! Blimey! Begad! Blimey! This guy had used a Digital camera t' take pictures from an RC glider. Avast, me proud beauty! Blimey! Well, blow me down! Blimey! And, he claimed it could be used in rocketry. Avast, me proud beauty! Blimey! Cool, me bucko, I thought. Ya scallywag! Blimey! So I began t' research t' DC 20 digital camera for rocketry use. Ya scallywag! Blimey! A normal 35mm camera could take 36 shots, ya bilge rat, but this could only take 8. Aye aye! Blimey! Oh well, it's better than one picture per flight. Well, blow me down! Blimey! So I got a DC 20 for me birthday. Aye aye! Blimey! I just got t' rocket controller, me hearties, me bucko, arrr, but that be no problem t' assemble. Avast, me proud beauty! Blimey! Arrr! Blimey! I added a phono jack with a nail in it t' use as a switch.
T' camera mount is simply a board o' 3/16 inch aircraft plywood and 2 centerin' rings made out o' t' same substance. One centerin' rin' has two holes in where a wire is looped. This makes it easier t' pull t' mount out o' t' BT.

With electronics installed
I used VCP t' come up with t' necessary stability calculations. Aye aye! Blimey! Eventually I'll post t' forward fin size, me hearties, etc. Ahoy! Blimey! (T' model uses forward fins t' make sure it will nay be overly stable. Well, blow me down! Blimey! I later found these are nay needed and broke them off) But for now, I'll just describe t' payload section. Ahoy! Blimey! T' body tube is a full length o' Estes BT-80 (2.6" diameter) with two strips o' folder material glued t' t' top and bottom o' t' BT t' add thickness t' t' Estes/Aerotech BT joint. Ahoy! Blimey! Begad! Blimey! It is covered with clear tape (masking?) for a smother transition. It has a 4" tube coupler made out o' corrugated cardboard with one layer o' paper peeled off. Well, blow me down! Blimey! T' lower bulkhead is 3/8" plywood with two holes for t' wire for shock cord/parachute attachment. Avast! Blimey! Above this bulkhead is about 2" o' paddin' t' absorb some o' t' lift-off stress. Blimey! Blimey! T' camera mount sits on top o' this and points t' camera out o' a small slit in t' side o' t' BT. Again, matey, t' tube is reinforced with folder material for strength. Avast, me proud beauty! Blimey! Finally t' Aerotech Initiator nose cone gets put on top. Begad! Blimey! T' whole payload section be painted gold. It is now painted red t' match t' cone.
T' original design:
After I snapped off t' fins:
T' first launch was on a F25 29mm Aerotech single use engine. Arrr! It supposedly broke 500'.
My newest booster is goin' t' be light enough t' loft t' camera on a D or E engine.
