Sketches

My Son's first go at M31 for GCSE Photography

Hi, I helped my 15 year old son to capture some images of Andromeda during the summer.  Images were taken on a guided Skywatcher Esprit 80ED using his unmodified DSLR. He's been processing the images in Pixinsight whilst learning to use it - with more success than me so far!  

He wants to use the image as part of his GCSE Photography exam next year and asked if I could post the image up here for comments.  He wants to know if there are areas he can improve so looking for any advice that's out there.....

Excellent image. Well framed, round, tight stars, background not clipped.

He could apply a pass of scnr noise reduction. This will "warm up" the colours. Atm, the galaxy has mostly cool colours. The core could do with more yellow/reds.

First class image, nicely framed, sharp focus and wonderful detail in the dust lanes. I would agree with Wim, perhaps a little more red/yellow in the colour balance.

I would give that a grade A or 1 or whatever the mark is these days?

Thanks, so far he’s been following lots of YouTube Videos, presumably there’ll be one for that as well.  Just need to get the PI process flow from him so I can have a go at a few of my more pathetic attempts...

Really excellent work.  I agree a quick use of SNCR process in PI to remove any green thats in there will help.  How many shots did he take and what settings ?

Tom said "Thank you but what am I supposed to do with the SNCR?"  Images were captured on his Canon 750D which is unmodified.  He took about 60 Lights and then calibrated and integrated 42 of the best in Pixinsight along with Darks, Bias and Flats.  Lights were 42 x 300s at ISO1600.

In Pixinsight load the final image you have posted here  and then open the SNCR process. I think it defaults to remove Green.  then drop the triangle on the image any green tint willl be removed.
