That is some image for such short exposures.

Quark chromo first light
Well the Quark Chromo arrived and this morning I got a very brief look and imaging session between clouds. Oh my goodness, I was not expecting the visual delight at all. No time to play with tuning, but could easily see the surface detail and proms. 32mm meade plossl, in a skywatcher 102/600 stopped...

Re: My first live stacks.
Nothing like a healthy discussion 😃 The thread summarises my position, my CCD viewpoint of old, compared to the new Viewpoint given by Robin in his talk. I intend to do some experiements therefore, to see the results. With the colour CMOS, using Robins equations, and my usual sky conditions, I will ...

Re: My first live stacks.
Well Rob, I cant give much of an argument against all those shots! To get F4 onthe CMOS, im using a 0.5x screw in reducer for the altair, cant use it on the QHY, so best is F6 for that at 1200mm. thanks for all the input by the way, I am flip flopping around I know. having gone through Robins equati...

Re: My first live stacks.
Brian, My view is to use the QHY10 for wider field stuff, at F6 , 1” pixel. But For galaxies and planetary nebs, globulars,I am trying to get either my CMOS mono/CMOS colour working well for LRGB, or if its up to it, just the colour CMOS on its own. ive learnt alot about CMOS use from this forum. Ju...

Re: My first live stacks.
1600mm Rob, but thats at F8 , that gives 0.77” pixel which is OK, but slow. With the reducer gives F6 ish around 1200mm or just over 1” pixel, great from nebulae etc The CMOS gives 0.8” pixel at F4 , which is why id like to get it working good, no wasted FOV on galaxies and planetary nebs, ideal res...

Re: Yet another guidescope question
yep thats about the size of it Bob.
I find that Sharp cap doesn’t need a full 90 of the RA axis rotate to work either,
Just gives a bit of breathing space by setting the camera portrait.

Re: Yet another guidescope question
I use a 285mm focal length with the Altair 1280x980 pixel chip,
Which gives only a 1x0.7 degree field I think.
Works fine, but i have to orientate the camera so that when i rotate the Ra axis, it moves horizontally on the longer side of the field, if you get my meaning.
Has never failed yet.

Re: My first live stacks.
I registered years ago Dave,
Haven’t used it much though.
I like the QHY10, but with 6.01 pixels, its not good on high res for galaxies.
I am going to try the shorter exposure but many more of em approach on the next outing,
See how it copes.
