IC 410 Tadpoles Nebula with a smart telescope

IC 410 Tadpoles Nebula is a emission nebula about 40 arcminutes (0.67°) across. It is highest around midnight in December, best placed for the northern hemisphere, and works from a suburb; a darker site gives a much cleaner result. Of the 14 smart telescopes we track, Seestar S30, DWARF mini, Seestar S50 Pro frame it best.

Imaging tips

This type glows in the specific colours of hydrogen and oxygen. If your smart telescope has a dual-band or light-pollution filter, use it: it blocks much of the city glow while letting the nebula through. Tadpoles Nebula is a reasonable target from the suburbs.

Mosaic planner

Tadpoles Nebula is larger than the frame of some smart telescopes. A mosaic covers it with several overlapping frames that are stitched together afterwards. Pick a telescope to see the layout.

12
Odyssey · 0.75° × 0.56°: 2 × 1 = 2 panels Each panel needs its own exposure, so plan about 2× the imaging time of a single frame.

Calculated with 15% overlap between panels and a 10% margin around the object, with the frame lined up along the object's long axis. When the object is longer than the short side of the frame we always count at least two panels, because on an alt-az mount the frame turns during the night. Whether a telescope has a built-in mosaic mode depends on its app and firmware; you can also shoot the panels separately and stitch them yourself.

How high it gets from where you live

Highest altitude above a flat horizon. Below about 20° the image suffers from haze and light pollution; trees and roofs often block it completely.
