This is an mixture of the 4 pane Ha data taken with the ODK10 and the OIII data taken from a 4 pane mosaic that I did with the Takahashi FSQ85 about 2 years ago. This has saved me collecting equal amounts of OIII data to directly match the Ha data.
This is totalling 44 hours worth of total data (36hrs of Ha and 8 hours of OIII)
Sh2-101 the Tulip nebula
Ever since first capturing this target I've always wanted to go in closer.... This year I decided to do it and so here is the start of the Tulip nebula...... I'm hoping to gather OIII and SII data and make this a Hubble palette image.
So far this is 14x1800s in Ha.
The Cygnus Wall complex in mono
This is my completed mono 4 pane mosaic of the Cygnus Wall complex. Taken with the ODK10, it needed a 2x2 mosaic to fit it all in. This is 18x1800s on each pane, so 36 hours so far.

After capturing 101x1800s combined in Ha and OIII for the Crescent nebula, I thought it may be of interest to show a comparison between the two lots of data.
I know that the outer halo is something of a difficult capture and it really does only show up in OIII........ The comparison is 50x1800s in Ha and 51x1800s in OIII. There really is some quite pronounced differences.
Here's an Ezine written by Orion Optics featuring a short article about me and why I picked the ODK, with some images and information from Barry at OO.
Enjoy the read!!
This is my final version of M16 - The Pillars of Creation. It has been taken in bi colour and so only uses the Ha and OIII filters.In total this is 22 hours worth of exposure..... The data was pretty good and I didn't feel that I needed any more.
This has sat on the PC for days and day - It's such an iconic image - Can I compete with the Hubble image out there? I welcome your thoughts as I'm still not sure!
