3D Printed Accessories for Astrophotography 

Here is my latest Youtube  video on 3D printed accessories for astrophotography. I have designed and printed quite a few items that have been extremely useful, and saved me a load of money in the process. It’s not that expensive to own a 3D printer, and it would pay for itself really quickly in this expensive hobby, so what not give it a go. The software of choice for me to design my accessories is Tinkercad, which it totally free and available as an online account, so your account can be accessed from any PC on the internet. Please take a look at this video for some ideas from myself and others.

4D Balancing of CEM Telescope Mounts

Check out my latest YouTube video. Balancing any mount is really important, when you want the mount to track the night sky as well as possible, and as accurate as possible. Balancing a GEM mount in 3D is a well known procedure, but Centre Equatorial Mounts or CEM for short, are a different beast altogether, in this video I show you how I balance my mount in all 4 dimensional axis, and also how to add a DIY counter balance weight for mounting on the saddle of my CEM70 mount, and links to the parts needed on Amazon.

Touptek Toupcam IMX571 Review, Part 1

Touptek very kindly sent me this fairly new camera to use for a short period. So due to the very poor weather we are having here, I decided to split the review video into two parts, the first part showing the unboxing, connection to PC and some very basic indoor testing on the PC.

Hopefully in a few weeks I will get the camera connected up to my imaging telescope and get some real world testing done and hopefully some images, and this will form part 2 of the camera review, so stay tuned for that.

NEW Mele Overclock 4c full review

Mele computers reached out to me a week ago after seeing my review on their superb Overclock 3c mini PC. They have sent me their new Overclock 4c to do a full review on. Well, it arrived a few days ago and so I have been using and testing for the last 48 hours, and i am very impressed, the video is here on youtube YouTube, and also in the YouTube videos section of this website…

This is the first item that has ever been sent to me free of charge and I don’t have to return it either, but it has not biased my review at all, they have no creative control over anything I said about the product. 

So take a look at the review and leave any comments you have.

Pac-Man Nebula Imaging session

Pac-Man imaging session in NINA

Pac-Man imaging session in NINA

Tonight I thought I would have a go at imaging the PAC-man nebula, I tried this a few years ago with my then CCD camera, and did not come out too well. So using my newly acquired Optolong 3nm SHO filters, I settled on 50 x 180 second sub exposures through each filter.

The night started pretty good with guiding well below 0.6 RMS, as you can see in the image on the left, which shows it as low as 0.39 RMS, but as the night progressed it slowly but surely increased into the high 0.8’s, I relayed this was due to the very poor seeing, and although I constantly adjusted settings within PhD2 it did not get any better for the rest of the night. I managed 50 x 180 second of Ha and OIII, but had to get the SII a few nights later. The PAC-man does need quite a bit of integration and I totalled about 7.5 hours, which is not a great deal for this target, especially as there is very little signal in SII.

The stacking, calibration and all processing all done in pixinsight, was a bit of a challenge as the Ha data completely swamped the OIII and the little SII, so took quite a bit of work to get to the final SHO palette i was haply with.

The final processed PAC-man nebula image is below, and also in the gallery pages, with more capture details.
