Cassiopeia with a lot of Heart and Soul

[geeklee]

A recent run of sessions (mainly short ones) has allowed me to accumulate a mixture of data - primarily focused on the Heart and Soul nebula.

First though, lets start off with the big picture.  This is a 24 pane mosaic of the Cassiopeia constellation in Ha.  Taken with the Samyang 135 @ F2 and 183MM - just 5 minutes per pane.

Here's the annotated version showing the wealth of objects around this region:

 

Coming in a little closer, here's a 6 pane SHO mosaic of the Heart and Soul nebula together with the double cluster.  Taken with the RedCat 51 and 294MM.  Each pane has 2x600s Ha, 1x600s OII and 1x600s SII.

Taking just the Heart and Soul nebula, here's an image taken with the Samyang 135 @ ~F2.8 and 183MM.  It's around 11 hours of Ha and 4 hours of OIII.  Palette is from here.

Lastly, in the centre of the top "big picture" there is IC59 and IC63.  Here, it's taken with the RedCat 51 and 294MM - an HaRGB image (90m Ha, 60m R & G, 27m B).

It's such a rich region and I'm barely scratching the surface here.  Thanks for looking.

Additional technical detail can be found via my Astrobin link in sig.

What a project! Brilliant job all round. I love the annotated image showing the wealth of targets you've captured.

My favourite is the 6-pane SHO of the H&S and double cluster.

Thanks for sharing.

Cracking set of images Lee, particularly for such short integration times.. well done

These are sooo good!

Excellent work.

Amazing collection. I really need to get my ASI294MM attached to the Samyang 135mm F/2

These are great images Lee. The top one is really fantastic.

I seen the Heart and Soul plus double cluster image over on Astrobin and it really is rather nice, great work

Brilliant images and the effort taken to present the information is top notch too!

Excellent images Lee, you've done a great job on each of them 🙂

Wow, that’s a pretty good catch you’ve got there.. amazing results.

I loved everything about this, from the large mosaics to the deep HOO.

@geeklee Love the thought, execution and presentation!

Thanks again everyone ( @Adreneline @Laurin Dave @vlaiv @michael.h.f.wilkinson @mackiedlm @Stuf1978 @scotty38 @nephilim @Sp@ce_d @jjosefsen @clarkpm4242 ) for your comments and feedback, it's really appreciated and I'm glad each person could enjoy a particular FOV / image (or everything).

Some feedback from Adrian (@Adreneline) on the "big picture" mosaic got me thinking and onto an interesting way of bringing together these recent images.

Takes your breath away those images

Brilliant

Fantastico!  Too much goodness for one thread!
