Rassin’ frassin’ satellites!

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 →

Waning Moon, 24th August 2019

Posted on August 29, 2019 by james

Another clear night, another moonshot… Pleased with this one. Copernicus seems to have come out well and there are plenty of hints of high peaks beyond the terminator. Lack of sleep means I can’t recall the exact circumstances at the … Continue reading →

Waning Moon, 23rd August 2019

Posted on August 29, 2019 by james

I’m such a martyr, I really am 😀 It was mostly cloudy last night so I’d abandoned all hope of imaging and got into some development work on oacapture/oalive. Time passed quickly, as it does, and before I knew it … Continue reading →

Waning Moon, 21st August 2019

Posted on August 29, 2019 by james

Three nights on the bounce! But this one was a bit of an adventure. What was foreast as a few of hours of clear sky after the Moon rose stopped about two minutes after I kicked off the run to … Continue reading →

Waning Moon, 20th August 2019

Posted on August 29, 2019 by james

Two nights in a row clear enough to get an image of the Moon! Best 45 of 100 frames from the 450D and 127 Mak again, but this time 1/500th sec exposure to try to reduce the effects of wobbly … Continue reading →

Waning Moon, 19th August 2019

Posted on August 21, 2019 by james

So, a newly-aligned mount and just past full Moon, what’s a chap to do? Well, when the sky gives you moons, make moon images! I broke out the 127 Mak and 450D and dropped them on top of the HEQ5. … Continue reading →
