This is one of those retrospective posts of an image I took way back in 2019. IC4604 Session Data Date: 15/04/20219 Time: 17:09 – 17:52 UT Seeing: Unknown Transparency: Mostly Clear, Temp: Unknown Air Pressure: Unknown Humidity: Unknown Dew Point: Unknown Wind Speed: Unknown Scope: Televue P127 APO f/5.3 Camera: FLI Proline PL1608 Filter: Astrodon Ha Calibration: Dark and Flat subtracted. A remote imaging session using T9 in Siding Springs Australia. I know this…
NGC 224 -M31
I finally managed to get a good spell of clear weather in New Mexico. M31 is such a popular target for imagers and we see so many images of it, but it really does suit this scope and camera combination. I also wanted to practice my processing skills in Pixinsight, especially as colour is not something I have done much of. This is an assembled LRGB image. The luminance consists of 11 x 300…
IC 5146 Colour
I’ve managed to acquire the colour data for the Luminance image acquired last January. The RGB date comprises of 7x 3min subs for the R,G and B channels. I initially processed this as an LRGB image, but wasn’t happy with the result, so I overlaid the RGB data over the top and created a hole in that layer for the LRGB section of the nebula to show through. Yes, the stars are a little…
iTelescope
My first deep sky image using the scopes on the iTelescope remote network. The images were taken over two days on the T14 and T20 scopes in New Mexico. Both scopes use the same Takahashi 106mm refractor and SBIG camera. The great thing about the remote iTelescope network – apart from the obvious dark and clear skies in places like New Mexico and Siding Spring, is that the raw FITS files you receive are…
I’m Back….I think!
It’s been a while since I last posted. The weather here has just been terrible and to be honest I have given up on trying to do Astronomy here in Cornwall. Since my last post I have given variable star observing a go using the remote telescope network in the US. Yes, it’s expensive at about one US dollar a minute, but if added up what I have spent on my observatory over the…
Winchester Weekend 2017
The Winchester Weekend is the astronomical equivalent of Ascot to horse racing or Le Mans to endurance car racing and Wimbledon to Tennis…You get the picture. Held once a year around Easter, it’s a three day event where we all camp out in the student accommodation at the Agricultural college at Sparsholt in Hampshire. The weekend starts on a Friday morning, where a number Kernow Astronomers all bundle into cars and head East. Well…
