Hi Guy’s,

To help us celebrate our first year of business we are holding an astrophotography Workshop with Tom O’Donoghue. Please book your seat by sending me an email at This email address is being protected from spambots. You need JavaScript enabled to view it. to guarantee your booking.

Tom O’Donoghue has been an Astrophotographer for 9 years. Tom began imaging with an 8 inch SCT and DSLR from the suburbs of Dublin in 2005. These days he uses 4 inch Takahashi refractors coupled with full frame CCD cameras, from the South of France, and shortly again from the Wicklow mountains. Tom spent 3 years imaging from the Almanzorra valley in the south of Spain, where the weather allowed for the many nights of data needed to build up the large scale mosaics that is favoured style, wide field imaging.

In 2013 Tom was the Runner up in the deep sky category at the Royal Observatory Greenwich, Astronomy Photographer of the Year. He was also the Overall Runner up in Spain's Las Palmas Observatory Spain Imaging Competition 2013. (See image below)


Tom has held 2 exhibitions in Dublin in 2010 and 2012. He has also given various talks to camera clubs, and has exhibited his large size framed prints at Star Parties in Ireland.

This will be an intensive one day astrophotoghphy course. Please feel free to bring along your own images and we will show you the best way of processing them.

• What is a dark frame? DSLR and Long Exposure NR.
• Taking dark frames. Same exposure and same temperature.
• What is a flat frame? Flat box and Luminescence screens.
• Taking flats at the same focus.
• Keep the ADU to approx. 30-50%
• Bias Frames.

Pre Processing:

• Different types of software available.
• Stacking the Darks with Median settings- Master.
• Stacking the Flats with Average settings- Master Flat.
• Making the L, R, G, B stacks. FIT - Dark / Flat.
• Delayering CCD / DSLR Colour images
• Aligning RGB to Luminance in astroart

Processing:

• Screen settings in pixinsite and Photoshop. Adobe RGB
• STF in pixinsite. Linear verses Non Linear mode.
• Crop both images to match pixinsite.
• DBE / ABE in pixinsite. Gradient Xterminator in Photoshop.
• Histogram in pixinsite. Masked stretch in pixinsite.
• Levels Curves Photoshop. Flat to finish, Dim, Mid, and Bright zones.
• Contrast boosts Luminance. Micro curve adjustments.
• Masked sharpness for Luminance. Object masks to blend in bright areas that were sharpened.
• Noise Reduction and Smoothing. Pixinsite and Photoshop.
• HDR pixinsite and Photoshop with masks.
• RGB Background Neutralisation, Colour calibration pixinsite verses Colour Balance Levels and Curves Photoshop.
• Masked Saturation pixinsite and Photoshop.
• LRGB combination. Pixinsite and layering in Photoshop.


Processing Tips:

• Stacking Star Trail images in Photoshop to show through each layer.
• Star Minimising pixinsite morphical Transformation v Star Min in Photoshop. Star minimum for Blue channel if your scope isn't an APO.
• Correcting non round stars in Photoshop.
• Image Clean up. Pixels and colour range select and remove.

Hi All,
Yes I'm really looking forward to this. There is a lot in that list above, so hopefully we can get through it all or most of it.
I'll be concentrating on the processing side, both in Pixinsight and Photoshop. I can do parallel runs in both pieces of s/w to show how to take the FIT files to a final version. Bring your laptops and images, we may get a chance to play with the images in class as a tutorial. I hope to bring some of my data which I could give to people to practise with, either in the workshop or later themselves. There are only 8 seats left I believe, so its great to know there is an interest in this. Looking forward to seeing you there next week.
Thanks Tom.

Thanks for the messages guys, glad you enjoyed it.
There was too much to go through I didn't get to show all that I wanted to on the day.
Don't forget to send on any questions you might have on your processing. I'll do my best to help you out.
Tom.

Hi Tom/Carl,

Many thanks for organising and presenting the workshop last Saturday. I'm pretty much a newbie to astrophotography but learnt a lot about the software. Sorry I had to skip off early as I was pretty tired after a crazy week of late observing, meetings, and more.

Talk soon,

John

Hi Guys,

First of all we would like to thank everyone for coming along to Tom’s workshop. Sorry of the late post as I’ve been under the weather all week and just back at work today. It was great to see so many people from all around Ireland; it just goes to show the popularity of astrophotoghphy in this country. We’ll be holding loads more talks and workshops over the coming months so keep an eye on our IFAS page for dates and times.
