NGC 3324 is a star forming region at the northwest corner of the Carina Nebula. It is called the Gabriela Mistral nebula, because of the resemblance with the Nobel Prize winning Chilean poet. It’s shown in the center of this image, with Eta Carina Nebula to the left and NGC 3293 upper right.
Dark cosmic dust spreads across the Corona Australis constellation, with light from hot blue stars reflecting a blue glow. Top right of the image also contains NGC6723, a globular cluster in Sagittarius. There’s a lot happening in this image, I have to thank Cory for giving me this target idea to shoot as it […]
In May 2013 I photographed M16, acquiring 21x 180sec exposure images to total 63min. I initially calibrated and stacked in Nebulosity, and edited in Photoshop. Since end 2013 I’ve moved over to processing in PixInsight, and have been wanting to reprocess some of my previous images.
Tanja & Cory will be speaking at the West Rand Astronomy Club February 26, 19h00 Venue: Dutch Reformed Church, 844 Corlette Avenue, Witpoortje. Telescopes will be set up for viewing (weather permitting) Cost: Donation of R10 for use of the venue which includes tea / coffee (Unable to attend? Leave your question in the comment […]
To connect your DSLR to a telescope you simply need a T-ring and T-adapter. The T-ring attaches to the DSLR and the T-adapter to the telescope. The T-adapter 42mm thread is a worldwide standard to connect cameras to other devices, but T-rings are brand specific, like lenses.
I recently did a blog about acquiring and processing M42, “Processing the star factory”. Revisiting my image, as one does when it’s cloudy for months…. I realise that there is more data buried in the image. I fear over processing, and I hate adding noise to images. My approach is always a little reserved and […]
By Tanja Sund and Cory Schmitz The magic of long exposure astrophotography reveals so much more of our universe: a plethora of colours and structures that tend to go unseen by the naked eye. From wide field lens photography to imaging through a telescope, astrophotography remains the pinnacle of long exposure photography.
The German Equatorial Mount Static photographic tripods offer vertical movement and head rotation, but they lock into place. Telescope mounts work in a similar fashion, but can move in right ascension and declination – the coordinates of the sky.
During my May 2013 Sutherland trip I photographed a lot of targets. As the Milky Way core was rising, Carina was setting. I managed to get a few images in before she set but left the data unedited the last few months as I was frustrated with some PixInsight processes. I revisited my last edit, […]
With clear nights limited during my summer months I took the opportunity to image the Carina Nebula from home with a gap in the clouds. Unfortunately imaging time was limited on this as I could only photograph it from 2am onwards, with sunrise before 5am and clouds at 4am…. and light pollution in the mix. […]
