The histogram settings are very intuitive and responsive

Thanks Martin.
I have identified the cause of the oval star shapes..the camera etc was not tightened down..I meant to put some boot polish on the threads and had left it slack...and remembered that after I had tightened everything tonight...I got excited knowing that I had found the problem....there is still something a little off but I wont panic until I fix everything and fixing tilt does not worry me ..I will pull it apart tomorrow and boot polish where appropriate...so a step forward..I took about 100 at 30 seconds at zero gain ( of ETA) and staking them now to see how things look...no flats as I have to get a T shirt or tshirts..all mine are black..'
the batinov mask I have does not work but I can focus by blowing up the field and picking a big star and a little star very close and to see each focus has to be just right..I am getting used to it ..why the mask does not work is beyond me..my mask for the 8 inch seems to work but I was hand holding it so I will make something to hold it and give it a fait trial.
So as usual I get everything running and come up to the van for some coffee etc and of course finish that ready to go down and change the filter and it has clouded over and the dew is horrific...so good because it means I can shut things down and watch youtube...make the best of it...however I am getting things done..baby steps but heck I really did not think I would be around so.....very happy dew and all.
Thank again to everyone...I know that without the help I get here I would not be able to do a thing ...
