The imaging sensor in the DSLR is actually just as sensitive as most other astro-cameras to the hydrogen-alpha wavelength; however, for daytime use, DSLRs are manufactured with a filter that blocks deep red through infrared (IR) light in a way that a typical astro-camera with an IR/UV cut-off filter does not. Fortunately, there is a way to make your DSLR more sensitive to this light and bring out these details in your deep sky images.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
