Some Marseses…

… as Gollum might put it.

Reprocess of my data from 13 September,



From Thursday last week:

More Mars
More Mars

And the day after, Friday at Rosliston, the seeing wasn’t as good and Mars wasn’t as high in the sky:


All with the same equipment, so sometimes it’s just down to the conditions… Andy’s to be congratulated for getting recognisable images on his first go under such poor seeing.

Photographing Mars during RAG observing session

With Neil Wyatt’s help, I have managed to take my first photograph of Mars – I am very excited!

  • ZWO ASI174MM camera
  • Sky Watcher Equinox Pro 100mm OTA
  • HEQ5 Pro mount
  • I used Pole Master to polar align.
  • I learnt that SharpCap to take the photos – I discovered this is better than FireCapture & ASICapture.
  • The image on SharpCap needs to be quite bright – so change settings so histogram about 75% – initially I took video which wasn’t so bright & then AutoStakkert would not recognise the planet.
  • I also need to use 5x Barlow to reasonable image scale.
  • To focus – need to focus on star first as difficult to focus on planet.


Sky watching in Flamborough, Yorkshire

Had a couple of chances to do some sky watching when on holiday last week. Mars was clearly visible when the sky cleared. It seemed that it took quite a while for the sky to get dark enough. The moon was looking good. I was able to look out of the velux window in the bedroom, and see the moon out there. On one evening the Milky Way was visible, not too clear, but you could tell it was there.

My favourite version of this image:

In image below, I have taken sharpening to an extreme – brings out some extra detail but at expense of making image seem unreal:
