Thanks Olly for reminding me to look at the obvious first!  Checked my subs and much to my embarrassment discovered the 'smudge' only appeared on the last sub!!!!!

I'll have a careful look at the individual subs Olly.  There's not much light pollution where I live so can't think where an external light source might come from but will have a good think about that. . perhaps it's something about my imaging train but wouldn't that affect all /most of my subs?

Thanks

This is just 8x300sec  blue stacked in DSS of the Leo Trio but something has  obviously gone wrong.  It only appears on the blue filter not the red, green or luminance.  Imaged with Takahashi 106ed and Atik 460ex.  I've just done a quick process using auto Camera Raw to show the large smudge!  I've no idea what has caused this and would appreciate some help!

Thanks

Annie

Dave - just to say I ordered and have received the dual channel dew heater control as per your suggestion at: /www.dewcontrol.com/Dual_Channel_Digital_Dew_Controller/p3099125_13437758.aspx    It looks well made, and arrived quickly.  Looks just the job - thanks.

Annie

Super sharp image!

Thanks Alan - my diy has improved since I started imaging but still not great!  I don't need pc control  so may have a look at Dave's suggestion.  I did think the two I mentioned were a bit overpriced so am pleased you reinforced that.

Thanks Dave am going to look at your suggestion.

Am looking to buy a new dew heater control - a dual one is all I need so have been looking at the Kendrick and Pegasus one, £107 and £99 respectively.  Is there much to choose between them and are there any other options I might consider.  I have plenty of Kendrick dew tapes.
