Lagoon M8 and Trifid Nebula M20

Lagoon M8 and Trifid Nebula M20 captured with an 80-210 mm Tamron telephoto lens set at 210 mm f/5.6, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera on a 30 mm f/4 guide scope. This photo was imaged and tracked using a DIY go-to telescope … Continue reading Lagoon M8 and Trifid Nebula M20

Trifid Nebula M20

Trifid Nebula M20 captured with a Vixen R114 reflector, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera on a 60 mm f/5 guide scope. The dark dust lanes that divide the nebula into three sections are visible in this photo. This photo was imaged and … Continue reading Trifid Nebula M20

DIY Upgrades for a Newtonian Reflector

This post features all the DIY modifications I have made with a Vixen R114 Newtonian reflector on a Grand Polaris equatorial mount. Buying a Telescope in the PhilippinesAcquiring a telescope for astrophotography may be very costly if it is to be purchased brand new, with prices usually costing (in the Philippines) more than 35,000 pesos … Continue reading DIY Upgrades for a Newtonian Reflector

DIY Telescope Controller | OnStep

I have built a controller for my Vixen Great Polaris mount using the OnStep go-to telescope controller. I used an Arduino Mega 2560 as the main controller board, a pair of LV8729 stepper motor driver, and an HC-05 bluetooth module (which connects to the OnStep Android app). I also built a Smart Hand Controller (SHC) … Continue reading DIY Telescope Controller | OnStep

Vixen R114 on Great Polaris Mount

I have recently acquired a Vixen R114 Newtonian reflector (114 mm aperture, 900 mm focal length at f/7.9) on a Great Polaris equatorial mount. The mount does not have motors, but I have converted it into a fully-automated go-to and tracking mount capable of unguided exposures of at least 60 seconds (field-tested without guiding). The … Continue reading Vixen R114 on Great Polaris Mount

DIY Microfocuser for a Telephoto Lens

I’ve built an electronic automatic focuser (EAF) for my Tamron 80 to 210 mm telephoto (zoom) lens for automated and precise focusing. The focuser was built with a stepper motor, an A4988 stepper motor driver, an Arduino Uno, and a repurposed azimuth adjustment mechanism of an old Vixen mount. Vixen’s alt-az mount azimuth lock mechanism … Continue reading DIY Microfocuser for a Telephoto Lens

DIY Tamron to Astrocam Adapter

I have a 1980 Tamron 80 mm to 210 mm telephoto (zoom) lens that I intend to use for astrophotography. I could not find a dedicated astro camera adapter for this particular lens so I just improvised one. I used epoxy to connect a Tamron to Canon EOS adapter and an M42 connector for my … Continue reading DIY Tamron to Astrocam Adapter

DIY DSLR Filter Modification

I have performed filter modifications on a number of DSLR cameras (Canon 450D, 700D, 1200D, 500D, 1000D, 1100D, Nikon D3100, and Fuji X-A1) for me and my colleagues. It involves the removal of the stock UV-IR filter, making the camera more sensitive to H-alpha wavelengths. This modification is helpful only when shooting targets with H-alpha … Continue reading DIY DSLR Filter Modification
