Captured the Carina Nebula last night probably for the last time until next summer
Conditions were reasonably good ( no wind, no dew , no moon , no mozzies ) although seeing and transparency were average

Yes all newtonian reflectors project diffraction spikes caused by the spider vanes on the brighter stars when you observe or image
Some folk don’t like them but I feel it adds a bit of character to images
Hi Martin,
Really good images you have captured of Eta.
Sharp, spot on colour, stars are tight as of all your work. You keep producing these great images and lots of them.
Love the detail.
Have you put these into a mosaic?
A 5 inch scope is the perfect framing for Eta so with your 8 inch you get really good detail but of course cropping.
If you haven't all the data you still have a little bit of time to get the rest as in Sydney it crosses the meridian at around 8:40pm.
It would make a really sharp mosaic with an 8 inch.
Hope i'm not putting you under pressure but with your record of brilliant images a few more will make a perfect a really great shot.
Cheers
Andy
Thanks Andy
I was just seeing much detail I could see when cropping and resizing
You do lose resolution but there is a fair amount of detail there
I wasn’t planing doing mosaic
Thanks for your kind comments
Cheers
