Amateur Astronomy from Edinburgh

This website is a place where I can post my images purely for the fun of it. You can find more information about the equipment I use on the About/Equipment page. Some of my best images are on display on the Showcase page.

To give me something to aim for, I have set up pages to get as many Messier and Lunar 100 objects as I can. The Deep Sky page is for objects not in Messier’s catalogue and includes some more recent lists such as the Caldwell and Finest NGC catalogues.

Light pollution is a serious problem for amateur astronomy here on the edge of Edinburgh, Scotland, so this is a battle of photons vs sodium! Please come back and visit as the site develops, I make lots of mistakes, the weather gets worse and the skies get brighter.

Updated 2015-10-09 using the 460EX. Older one below.
Low surface brightness. Hard to image effectively.

Second attempt at this with the 460EX. 2 nights of data. Meridian flip reduced time.
This is the first time I’ve tried final processing and touch up in Adobe LightRoom.

NGC 7635 Bubble Nebula (C11) with 460EX

First real LRGB image with the new 460EX. Still need to improve processing. I have some Ha from previous night to add in too but not sure how to do it.

First chance to try out the new 460EX properly.

A “mucky” night with low transparency. Lots of star bloat but the camera has almost no noise at -10C. Processing still needs some work. Too many very red stars. Could be caused by the DS filter?

Cocoon from multiple dates and telescopes

First successful attempt at using different focal ratios. Not bad!
Using subs from 200mm f/5 newtonian and 2 different sessions with the RC8.

200mm f/5 newtonian 10x180s 4x240s, darks, flats,  ISO 800 2008-08-19

200mm f/8 RC 10×180, 20×240, darks, ISO 1600 2014-08-26

And this is what the stack looked like:

Update to M53

Finally got a chance to get outside. Bad weather for ages. Unfortunately the darks were duff, horrible hot pixels everywhere, so had to use old ones – not ideal. No chance for flats either.
