C4 NGC7023 Iris Nebula

2021-04-14T13:56:40+00:0014 April 2021|Caldwell, Nebula, News|

Another  for the ASE Caldwell Project. Horrible gradient to deal with but background is messed around with to bring out all the dust around it. Makes the rest of the background messy though.

Well the Soul Nebula Mosaic anyway. 5 panes in the end. First 4 panes (see below)  should have done it but I suspect platesolving failed and I had to do another pane the next night. APP is brilliant at stitching together and blending in panes – even from different sessions.

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!

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.

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

NGC 1977 test image

2020-12-24T12:08:48+00:0017 December 2020|Nebula, News, NGC Winter|

Testing out and configuring replacement laptop after old one got washed away in observatory leak! Took a few frames of the Running Man nebula. Topaz is great for removing noise in images with too few frames. This only had 4 frames and once stretched was very noisy. Looks great after Topaz-ing.

Last one was narrowband, this attempt is full colour with the CMOS camera. Also first time using NINA for capture. Looks a great tool.

The Iris Nebula is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487. The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star designated SAO 19158.

New QHY168c camera test on Eastern Veil

2020-09-17T08:01:27+00:0025 August 2020|Nebula, News, NGC Summer|

New camera testing. Different way of working with Gain and Offset needing to be chosen and probably using more shorter exposures than the CCD.
32Mb lights instead of 10Mb for the CCD means much longer processing in APP. Couldn’t use the flats as I moved the camera between flats and lights.

Imaged areas around this a lot for HOYs but never this actual part. First time back using the MPCC without the LP filter this time to avoid internal reflections. Stars are better at 3 corners but top right still off – probably focuser alignment.
