  1. That's a fabulous image Carole - true dedication over several years to finally pull it all together. The colours and field of view are great. I've had a shot at this from my UK site several times and have only half-finished images and poor quality data, with the target being so low it's amongst all the murk in that part of the atmosphere. I'd be mighty chuffed though to deliver an image of Rho/Antares as good as what you have, well done!

  2. Hi Si, welcome to SGL. I live near Kentisbeare, so pretty close to Honiton. I've been a past member of the Norman Lockyer Observatory, it's a great place to meet people and learn. Like you I started off with visual kit but soon moved across to deep-sky imaging and have been doing this for the last 10 years. You'll enjoy the hobby, although as you'll find the frequent lack of good clear nights can be mighty frustrating!

  3. Ian, that's a brilliant version of Melotte 15, top drawer, the details in the nebulosity and the subtle but effective palette have come through superbly, I also like the handling of the stars, no halos, no sharp edges, just lovely and natural - overall an excellent image, take a bow!

  4. I've had several red lights of various types, but the one I keep returning to is a small hand-held one from Inova. It's small, which I like, and red light only, but packs a real punch, excellent brightness on first setting, which you can tone down by clicking again going to the next setting. It surpasses by far the red light I have on my Petzl headtorch by quite some margin, and the batteries last for absolutely ages. You can buy the Inova red light torch from Amazon where it's listed as 'Inova Microlight Keyring Torch'.  

  5. John, as a first narrowband image this is excellent. When you mention removing pinpoint red stars, I assume you mean aberrant red pixels, there should be no bright red stars alone in the field if the stacked master files are aligned properly. Hot red pixels are not uncommon though and can be easily removed with a hot pixel map and substraction process - usually these disappear anyhow with calibration frames so just check the settings for how you are using these. Nevertheless that's a mighty good HOO image of this target - not over-cooked, and very well executed - well done.

  6. Thanks for your comments. It's difficult to get a decent run of clear nights here in Devon, especially when there's no Moon light around, but I may add some more frames to this this image to widen the FOV even further, so perhaps end up with a 4 frame mosaic - will need the night skies to play ball though!

  7. Taken over several nights late July and early August, this is a 2 frame mosaic taken with a TakFSQ106/QSI690 on a AP Mach-1 mount, data for each frame collected using CCD Commander and consists of 12 x 10 minutes H-alpha, 9 x 10 minutes OIII and 9 x 10 minutes of SII. Processed using Photoshop in hubble palette. Thanks for looking, Martin.
