Astrophotography auto guiding setup with a Mac (Part 1)

I know, I know.... it's been a while, sorry. Of course I did not intend to be away for quite this long, but heh, I'm back now.... I am slowly upgrading my kit. I guess you can never truly "stop". I have acquired a ZWO ASI camera and I have decided to tip my toe into the murky waters of auto guiding with this caveat - it will be Apple Mac based.I have found that this topic also gets forums alight from time to time and I hope to simplify the process and may be help to relieve people's pain. This is not an "Apple Fan Boy" post by any means, it is just that the Mac has been my machine of choice for a while and see no reason why I can't use this for my astro stuff.I have already got my eye on other software for image acquisition and processing too which I will hopefully follow up in later posts. So ...... onwards ........ My goal was to get PHD2 auto guiding working using an Apple Mac with a SkyWatcher HEQ5 Pro mount and a ZWO ASI120MC-S camera.

IC1396 - let's do a re-process.... erm.... are you sure.... yeh, come on....

For a while now I have been wanting to get more colour from my images that have been taken using a One Shot Colour (OSC) camera and a filter like the l-enhance narrowband from Optolong, and what do you know - I found some information to do just this. I came across a post on YouTube by a bloke I've been following for a while - Luke from Lukomatico ( https://youtu.be/YkxhGhuj3YQ ). He goes through a very detailed process of obtaining a Bi-colour/Hubble type image from an RGB capture using a software application called Siril (which I have used and mentioned on the blog before). I did use Affinity Photo to do some final tweaks too. All-in-all some very powerful image processing techniques that I will be using in future and playing around with much more too. Thanks Luke! :) IC1396 Elephant's Trunk Nebula in Cepheus Clear skies MJ

I just can't sleep!

Well. I woke at about 2:50am last night and popped my head around the curtain and they were there in all their glory. What? Noctilucent Clouds of course, or NLCs for short. Those really (and I mean really) high "night shining" clouds at approx. 80km in the mesosphere. So I stuck on enough clothes and a warm jacket, grabbed my camera and ran out the house to a fairly dark location down a narrow country lane near where I live. Noctilucent Clouds Canon EOS 5DMk2 ISO640 f/7.1 8sec. 135mm 2 panes stitched and processed in Affinity Photo Clear skies. MJ.
