Thanks mate.  I am going for getting plenty of objects in the bag before really spending loads of time on one object.

That's really good. You've done a great job on flattening the background sky. In the short time you had you've pulled out a truly worthwhile image so I hope a lot of people are looking at this.

Thankyou folks.  I moved up to five minute exposures on the Ha data and I'm not even bothering with a luminance channel on the nebulae and capture all RGBHa all at 1x1.  

I really like this widefield lark.   Although I do guide the rig, guiding is very much less of an issue with wider field rig.

Whether widefield or with the TEC140/Atik telescope, I am going to limit my max time on an object to four hours of integration.  It is not feasible in UK for me, with my circumstances, to spend any longer on one object.  My exception will be a widefield mosaic of the whole constellation of Orion this coming winter hopefully.

May the Lord be with you. My psychiatrist says that, four years on, I can expect periods of five minutes at a time of partial lucidity and freedom from paranoia but I am not allowed to associate with Tom O'Donoghue or look up in the south at night between September and May...

Worth it though Olly..  it looks really good on your wall 😊

Great image indeed! I assume some of the secret of getting such a presentable result after only 95 min is that you are shooting at f/2.8. Is that not right Olly @ollypenrice or have I fallen for the myth (I forgot what the myth really was)?
