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.

Reminder:

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

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

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.

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 🙂

M42 for 2017

2017-01-02T12:55:02+00:002 January 2017|M31-60, Nebula, News|

Got to do it every year – this is the 2017 version. Also trying out my new Revelation x0.75 reducer for the RC8. Seems to work very well for a very reasonable price £69. Spacing should be 80mm +/- 5mm. I managed to get 75mm with my filter wheel and 460EX.

M31 core

Haven’t visited this one for ages. FOV obviously too small to fit the whole galaxy in.
Had to stop after 6 exposures because sky transparency was reducing and dew was becoming an issue.
Dust lanes show up nicely.
