Baby steps around the Crescent

Posted on January 15, 2020 by james

With all the miserable weather we’ve had I’ve finally got things organised to do a bit of processing. Well, organised to do a bit of learning about processing really. When Photoshop-wrangling is required, I am only an egg. So, this … Continue reading →

Adding the TSRED279 reducer/flattener to the Photoline 72

Posted on November 9, 2019 by james

I’m very happy with my little Photoline 72, but with a camera sensor of any size it becomes obvious that the field is far from flat. So much so in fact that it’s sometimes difficult to get Deep Sky Stacker … Continue reading →

M27 revisited

Posted on November 9, 2019 by james

I first imaged M27 quite some years back and it has always been a favourite, so it being the summertime this planetary nebula was an obvious choice for an early target. This time I used the Skywatcher ED80 and Atik … Continue reading →

Progress with the Dumbell

Posted on August 31, 2019 by james

After my efforts on the Dumbell Nebula a short while back I’ve been collecting more data. I actually threw away my luminance subs and collected 250 minutes of new luminance data as 600s subs, and 50 minutes each of 300s … Continue reading →

Since the last release of oacapture I’ve mostly been working on oalive, an EAA-type application that will share a large amount of code with oacapture. One of the new things I wanted to do with this was to add support … Continue reading →

Rassin’ frassin’ satellites!

Posted on August 29, 2019 by james

All astroimagers know they can be a pain, but was there really any need for this on the first sub of an imaging run?

A couple of galaxies

Posted on August 29, 2019 by james

A couple more images from the Photoline 72 and ASI174MM last night. No filters, as for the earlier image of the Iris. M51 is 30 minutes of 90s subs, stacked, stretched and cropped, but no darks. Looking at the full … Continue reading →

A quick snap of Caldwell 4, The Iris Nebula

Posted on August 29, 2019 by james

Whilst the 80ED was working ok M27 last night, I had a bit of a play with the Photoline 72 and ASI174MM. This is 75 minutes of 300 second subs. No filters as I only have one set, but I … Continue reading →

Start of a new M27

Posted on August 29, 2019 by james

Other than a couple of weeks back as my first test from the new observatory, I last imaged this six years ago. It’s one of my favourites, so an obvious choice to revisit as I’m getting everything together again and … Continue reading →

Waning Moon, 26th August 2019

Posted on August 29, 2019 by james

I took 100 subs (1/500th @ ISO800) for this image at the end of quite a long night last night. The seeing had been excellent, but I’m not really happy with the outcome here. I think perhaps the DSLR doesn’t … Continue reading →
