M42 CCD Rc

2022-01-06T18:35:47+00:006 January 2022|M31-60, Nebula, News|

Was setup for an exoplanet transit but cloud got in the way, so took 4 frames M42 with the R-Cousins filter and CCD camera again. Not bad!

M31 tri-band test

2021-09-24T21:10:18+00:009 September 2021|Galaxy, M31-60, Narrowband, News|

Test to see if imaging M31 in tri-band is worth it. Yes! Detail in there that I haven’t seen in other images I’ve taken. Planning a 6 pane mosaic of the galaxy.

Didn’t expect to get too much out of this because of the high wispy cloud and only got 9 subs, but not too bad.

M42 Ha with Telescope Live in Chile CHI-1

2021-02-08T17:59:06+00:008 February 2021|M31-60, Nebula, News, Robotic Telescope, TelescopeLive|

Free trial of Telescope Live using one-click imaging (basically piggybacking onto other observations). It’s really not the same as doing it yourself, with your own equipment, from you own garden, with all the challenges. But when the weather is dire – it’s fun! Advanced, full control of the telescopes costs A LOT more. though!

M42 & NGC 1977 mosaic Dec 2020

2020-12-22T20:50:31+00:0020 December 2020|M31-60, Nebula, News, NGC Winter|

The annual M42 this year is a mosaic with the Running Man. APP dealt with the gradients really well after messing with the Normalisation and Integration parameters.

Mosaics in APP – defaults unless otherwise stated
1. Load – all as normal – you don’t need to use separate sessions for each frame if you did it all at the same time
2. Calibrate as normal
3. Analyse stars – I needed to increase from 500 or it wouldn’t work – went 1400 – might have been the subject but I suspect it helps to stitch the mosaic together
4. Register – Registration mode – mosaic, use dynamic distortion model, uncheck same camera and optics (will be suggested if you don’t)
Scale stop = 1 (for a 10% mosaic overlap)
5. Normalize – Mode – advanced – neutralize background
LNC degree – 2nd degree, iterations 3
6. Integrate – Enable MBB – 10% because I did 10% overlap in the mosaic
INTEGRATE – and if you’re lucky it all works

M42 for 2019 narrowband

2019-01-29T21:36:10+00:0029 January 2019|M31-60, Nebula, News|

This year in narrowband. Two attempts at colour mapping.
Need to get rid of the MPCC with this telescope as the image is better without. Too much star trailing with.

Poor night of transparency and seeing so just got this in the passing. Lots of sky fog that got processed out.

M31 first test of old 10 inch Newt

2018-11-06T15:51:38+00:0012 October 2018|Galaxy, M31-60, News|

First test of the old 10 inch Newtonian I picked up. Focuser and dovetail were a mess, but with some work it could be good. Optically pretty sound though.

M40 (Winnecke 4)

2018-09-14T22:06:56+00:0014 September 2018|M31-60, News|

Messier 40, also known as Winnecke 4. Basically it’s a double star, and an optical double at that!

It was discovered by Messier while he was looking for a nebula reported in the area by Johannes Hevelius. He couldn’t find it so he catalogued this double star instead. Most have been a slow night or something…

And why did I bother imaging it? Well it was in the only patch of clear sky there was and I only had a few minutes before it clouded over. Still, it’s another Messier object to add to my list 🙂
