DWARF mini: A Compact Smart Telescope With Autofocus
DWARFLAB
describes the DWARF mini as a compact smart telescope for birdwatching, scenic
viewing and beginner astrophotography. A smart telescope focuses, aims and
tracks automatically and is controlled through an app. The DWARF mini weighs
840 g, and users can control the lens manually, with a joystick or through the
app, which handles capture, scheduling and in-app editing. Setup is described
as taking about three minutes from unboxing to shooting.
How the Smart Telescope Works
The
telescope automates operation with autofocus, GoTo navigation and star
tracking. In equatorial mount mode, it compensates for Earth's rotation so long
exposures do not trail, and the page lists a 90-second long exposure. A
built-in IMX662 sensor, in a 1/2.8-inch format with 2.9 μm pixels, captures
2-megapixel RAW images. The lens barrel rotates 225°, and the gimbal allows
unlimited 360° rotation. Subjects named include the Milky Way, star trails,
nebulae, the Moon, the Sun, ISS transits, lunar and solar eclipses and
wide-field mosaics.
Filters and Scheduled Shooting
Built-in
filters include a dark-frame filter that automatically captures dark frames to
reduce thermal noise, an astro filter that passes 430 to 690 nm and boosts
nebula contrast, and a dual narrowband filter for Hα (hydrogen-alpha) at 656.3
nm and O III (doubly ionized oxygen) at 500.7 nm that reduces moonlight and
city glow. For scheduled shooting, users set a time and a target and the
telescope captures unattended, with the Andromeda Galaxy as an example.
App and Processing
In the
app, Stellar Studio offers automatic star correction, noise reduction and
nebula enhancement. The app supports dark, bias and flat field calibration,
frame-by-frame selection and multi-night stacking, which combines images
captured on separate nights. RAW files can be exported to Photoshop, Siril or
PixInsight. Social features include custom watermark signatures, collaborative
mosaic building with other users and eight achievement badges.
