Why are the stars I shoot always blurry while others' stars shot with DWARF II so clearly? Thanks to the Astro autofocus feature being released, this article will help you understand how to take clear pictures of stars.

Use Steps
1. Attention
The logic of Astro autofocus is as follows:
-
Find a naked-eye-visible bright star.
-
Roughly align the DWARF II lens with the bright star.
-
Find the bright star on the telephoto screen in the DWARFLAB app.
-
Use the astronomical auto-focus function.
-
After completing the auto-focus, proceed with astronomical photography.
Note: Please follow the following tips strictly before autofocus:
- Please find the brightest star visible to the naked eye to complete the Astro autofocus. The brighter the star, the easier it is for the astronomical autofocus to succeed; when the star is a bit dim, the Astro autofocus may fail.
- Please upgrade the firmware to version 1.3.23 or above, and the DWARFLAB app version needs to be 1.1.0 or above.
2. Use Steps
2.1 Use your eyes to find the brightest star you think in the sky (for example, Sirius).
2.2 Point the DWARF II lens towards this bright star.
2.3 Open the DWARFLAB app, connect with DWARF II, and switch to Astro mode.
2.4 Switch to a wide-angle view, and adjust the wide-angle camera parameters to the highest exposure (1s) and the highest gain (164), which can help us see this bright star in a wide-angle view.
2.5 Using the virtual joystick or dual-camera linkage function, adjust the bright star to the green frame in the wide-angle view (that is in the telephoto frame).
*The moving speed of DWARF II lenses can be adjusted by setting up the virtual joystick's moving speed.
2.6 Switch to telephone lens view and Astro mode, tap the 'FOCUS' button and then tap the 'Auto' button to complete the astronomical autofocus.
