Nebulae
IC 1805 Heart Nebula and IC 1848 Soul Nebula in Cassiopeia

Modified Canon 1100D through an Altair Astro Starwave 70mm ED refractor with AA 0.8x flattener/reducer. A Hutech IDAS-LPS-V4 nebula filter was used.
A total of 43 x 5 min exposures at ISO 400.

The FOV is approx 2.5 x 3.75 degrees, the reducer having converted the refractor focal length from 420 to 330mm. The focal ratio decreased from F6 to F4.8

The Heart Nebula (IC 1805; Sharpless 190; 100 x 80 arcminutes) can be well seen at lower left, with the Melotte 15 (Collinder 26) open cluster (mag 6.6; 21 x 21 arcminutes) at the centre.
The open cluster NGC 1027 (20 x 20 arcminutes; mag 6.7) can be seen just to the left of bottom centre.
The Soul Nebula (IC 1848; Sharpless 199; 105 arcminutes) is to the upper right.
