The Horsehead and Flame nebula in a more widefield context, This is a mono image, consisting of 27x1800s (13.5 hours of total exposure) - It;s interetsing to see the FOV differences between the Tak FSQ85 and KAF8300 chip and the Sony ICX814 chip with an 8" RC scope. Take a look here
Here's a target I have avoided for 5 years.... It was one of the first images I ever took and after a while relaised how difficult it is due to it's huge dynamic range... so there was no way I was going near it!! This year I submitted.... Here's my take on the Great Orion Nebula totalling over 26 hours of data mixed from different cameras, mounts and scopes!
Here's the best bits from 2016!!
Taken with a combination of scopes at different focal lengths (330mm and 1700mm) this has been a fun year. There's hundreds of hours of data in this montage. In trying to set up a dual side by side system I have come up against the enemy, differential flexure. This is some form of often miniscule movement between the two scopes that leads to elongated stars. Until now i have been using the Takahashi Clamshells. It's been suggested that these could be causing the small movements and so I've moved to scope rings.
Unable to easily find 95mm scope rings, I have bought and fitted Prima Luce rings and a Losmandy dovetail. An excellent and well made product I am hopeful that this will resolve my flexure issues. Read the equipment review here Finally after weeks......a clear night.
The moon is MASSIVE and the conditions with high humidity are far from ideal, but as this is a 2 pane mosaic I knew that I'd get away with it..... 9x1800s in each pane, more data needed but it's a start. This has been an interesting image to complete! This is a 2 pane mosaic of Ha data from the ODK10 and a 2 pane mosaic of SII data from the Takahashi FSQ85.
This is a total of 39 hours worth of data in total. You can see all of the information on Cederblad 214 and NGC7822 in this link. I've imaged this a number of times, and each time with a different focal length or style the image is different! Following on from my written guide on how to create an inset box in PS to highlight an area of interest, I was asked if I'd make a video of the process. Here it is .......
IC417 (The spider nebula) has been used as the front cover for the online magazine 'The Star Formation newsletter' published by the Institute of Astronomy in Hawaii.
You can see the magazine here Have you ever wondered how to create a magnified inset in an image so that you can highlight a specific area that may otherwise go unnoticed?
I've written an easy to follow guide so that you can do exactly that. Creating an inset in Photoshop Here you can follow the guide or download if it you prefer to print it and keep a copy. |
