Observing Diary – Supernova sn2017cbv

Date: 18th March 2017

Location: My Backyard, Melbourne Australia

On the 10th of March a new supernova has been reported in the galaxy NGC 5643. It has received the designation SN2017cbv and is reported to be a Type Ia event.

I took this quick shot of NGC 5643 during an observing session last night to see if I could spot the Supernova.

More Messier objects through messy skies

High, patchy cloud over my backyard in Melbourne lead to a challenging imaging session.

Each image was taken using my 10 inch RC scope and QHY 9s camera, 2 exposures of 300 seconds LRGB.

Observing Diary – At last there’s a hole in the clouds!

Date: 31 July 2016

Location: My Backyard, Melbourne Australia

A short window of clear skies allowed a couple of images of Messier objects, although I ran out of time to image M20 in Blue.

Each image was taken using my 10 inch RC scope and QHY 9s camera, 2 exposures of 300 seconds LRGB.

Observing Diary – The Tarantula Nebula

Date: 16 November 2015

Location: My Backyard, Melbourne Australia

The Tarantula Nebula
The Tarantula Nebula – Camera: Canon EOS 500D mounted on my 250mm RC scope f/8. Single 2 minute exposure at ISO 800.

A beautiful clear, warm night in Melbourne, allowing comfortable observing until the clouds rolled across at about 11:00pm

Here is a single exposure of one of my favourite objects, The Tarantula Nebula.

It really does look like a giant spider, hanging in its web, especially when you look at the wide angle view of the surrounds. The web of the spider spreads quite a way.
