Rosette Ha Tuesnode

[Rocket Pooch]

Hi,

Here's a quick Rosette from Tuesnode, could have done with a lot more data, but the mount decided to flip....

How many subs was that then?

Was it a crop or full frame..

That's not at all bad for the small amount of data you had.  The dark lanes are beginning to come out well.  Again, it's a good scale.

Nice image Chris, very smooth and detailed for 7 subs.  Was that the 6" Newt ?

How long were the subs?

Hi Robert,

It was the ZS66 with a .67 Reducer (hence the coma) so the scope was at F4 approx and 7x5 minute subs.  I need to decide if I'm going to get a WO Reducer or maybe a Tak FS60, need to decide, I'm not over impressed with the ZS66 nowhere near as good as an ED80.

That coma looks suspiciously like it needs collimation, if it was coma due to the reducer I would expect it to be pointing away from the center rather than towards the lower right.  That was exactly what I had with the Sky90 (but worse), after you pointed it out and I adjusted the images were a world apart.  What's the coma pattern like without the reducer?
