Session - 12/10/2023 ; Location - Horsens
Note: Wanted to test the new OIII filter for the first time, but was too lazy to do an alignment, so was not able to find the Veil nebula unfortunately. Interesting though, stars are green in this filter - so this answer the question "what wavelength is OIII?". Next time the weather and energy allows, I will do an alignment so I can use the GoTo
| Object | Observation type | Eyepiece/camera | Magnification | Filter | Note | |

| Jupiter | Explorer 150PDS (f5.0) | Plössl + Celestron 2X (fov: 0.4°) | 250X | Tried going max magnification, but a combination of low on the sky, and a semi-warm scope made the picture very fuzzy. Definitely should have cooled it of before the session, but didn't have the time. Still a nice view though, and was able to see the moons too |
|
|
| Saturn | Explorer 150PDS (f5.0) | Plössl + Celestron 2X (fov: 0.4°) | 250X | Tried both with and without the barlow. Same story as for Jupiter - very fuzzy. But still easy enough to see the rings. |
|
|
| M31 | Explorer 150PDS (f5.0) | Plössl (fov: 2.77°) | 18X | Tried also with the 6mm. Not really sure which I prefer. Probably I just prefer better observing conditions |
|
|
| M45 | Explorer 150PDS (f5.0) | Plössl (fov: 2.77°) | 18X | First time seeing them since winter/spring earlier this year. Felt like a warm welcome in the cold evening. Can't wait to see more of the winter sky |

|
| Mirfak | Explorer 150PDS (f5.0) | Plössl (fov: 2.77°) | 18X | After listening to the latest episode of Actual Astronomy about fall stars to know, I got inspired to have a look at Mirfak and Algol. Mirfak in Melotte 20 was really beuatiful, and I'm happy I had a look here. Open clusters are quite impressive to look at. |
