NGC188 (C1)
Never noticed this one before. Very close to the pole so easy guiding as nothing moves very much round there.

Rosette Ha mosaic 6 sessions
Still a work in progress. APP is great for doing these sorts of mosaics.
5000 pixel size reduced to 2000 for this.
| Object ID | NGC2244/2237 Rosette Nebula Monoceros |
| Details | 6 sessions over Jan – March 2020 |
| Telescope | 250mm f4.8 Newtonian |
| Camera | Atik 460EX Baader 7nm Ha filter |
| Exposure(s) | Nominally 6 x 15 x 300s but probably fewer since some will be discarded |
| Capture | APT |

IC405 Flaming Star Nebula HOO
Been trying to do this one for a while and finally got it.
| Object ID | IC405 Flaming Star Nebula, Caldwell 31 |
| Details | Size 37’x10′, Mag. 6.0 Auriga |
| Telescope | 250mm f4.8 Newtonian |
| Camera | Atik 460EX -15C |
| Exposure(s) | 10x300s Ha and OII 2×2 darks, flats, bias mapped HOO |
| Capture | APT |
| Processing | APP, Photoshop |
IC349 Barnard’s Merope Nebula
Thought I’d try and get the Merope Nebula as the whole Pleiades don’t fit in my FOV. But saw a flaw beneath Merope which turned out to be another nebula.
| Object ID | IC349 Barnard’s Merope Nebula |
| Details | Size 0.5′, Mag. 13 Taurus |
| Telescope | 250mm f4.8 Newtonian |
| Camera | Atik 460EX -15C |
| Exposure(s) | 3x180s ea RGB 1×1 darks, flats, bias |
| Capture | APT |
| Processing | APP, Photoshop |
NGC 2024 Flame Nebula RGB
Wasn’t expecting it to be clear so this is a bonus. Only managed 5 of each colour though so quite noisy and Alnitak overpowers eveything.
| Object ID | NGC 2024 Flame Nebula |
| Details | Size 30’x30′, Mag. 10 Orion |
| Telescope | 250mm f4.8 Newtonian |
| Camera | Atik 460EX -15C |

IC410 Tadpoles in Hydrogen Alpha
The two tadpoles are about 10 light years long and places of star formation.
