Christmas Tree Cluster NGC2264

The Christmas Tree Cluster and Cone Nebula (NGC2264) is located in constellation Monoceros and is about 2700 lightyears away from Earth.

Setting : Nikon D7500 and TLAPO80/480 f/6; lights 32x60s ISO2500 and H-alpha 21x90s ISO6400. Camera control with DigiCamControl and stacking using APP. Final editing with CS4 and DeNoise AI.

Collinder 69 Lambda Orionis Cluster

Collinder 69 (Cr 69), also knows as the Lambda Orionis Cluster in constellation Orion is an open star cluster and about 1300 lightyear away from Earth. The bright stars in the picture are Meissa (λ Ori) and Heka.

Setting : Nikon D7500 and TAL200K f/8.5, ISO800 and single shot of 30s. Final editing using CS4 and Denoise AI.

Planetary Nebula NGC2022

Planetary Nebula NGC2022 is located in constellation Orion (east from the star Meissa) and about 8000 light years away from Earth.

Setting : Nikon D7500 and TAL200K f/8.5, ISO1600 21x30s. Stacking with APP and final editing using CS4 and DeNoise AI.

Focussing with H-Alpha

Focussing with a H-alpha filter isn't easy when you compare it without a filter. I'm using a bahtinov mask everytime when shooting pictures. When using no filters, I'm using live view of my DSLR to see whether the star is focussed. In case of using my H-alpha or OIII filter it's getting difficult using live view. Even when I increase ISO levels and shutter time. 

To conclude : I slew to a sharp star (eg Sirius, Vega, ..) with either the H-alpha or OIII filter and bahtinov mask and take a picture. Based on the picture I'm adjusting the focus and take another picture. I repeat this workproces untill the star is focussed.

Orion Nebula and surrounding NGC and IC objects

Using astrometry.net I was able to localize 7 NGC objects and 1 IC object from my M42picture : 

        NGC 1981 Upper Sword

        NGC 1975 

        NGC 1973

        NGC 1977 The Running Man Nebula

        NGC 1982 or M43 Marian's Nebula

        NGC 1976 or M42 Orion Nebula

        NGC 1980 Lower Sword

        IC 420

Orion Nebula M42 & Running Man Nebula NGC1977

In total I run two sessions to capture the Orion Nebula, Messier M42.

First session : OIII en Lights

Second session : H-Alpha and Lights

Both sessions using Nikon D7500 on TLAPO80/480f/6. Camera control with DigiCamControl. APP software to stack all pictures and final editing using CS4 and DeNoise AI.
