So I had a free day yesterday and decided to sort out my equipment and update my astro laptop software packages. I downloaded the latest Stellarium and managed to get it to sync with APT. I installed my Xmas present from my sweetheart (Optolong L-eNhance filter) how did she know it's what I wanted??? I recently installed the free trial version of Pixinsight on my main laptop so after watching a few YouTube videos decided to get some Dark and Bias frames to create some masters ready for my next session. The weather was good yesterday and it stayed clear here as the sun started to set, so I set everything up outside hoping the apps were wrong and it wouldn't get cloudy. As it got darker I launched Sharpcap and completed a polar allingment, I used Stellarium and APT to slew to Vega and checked the focus was good. I then used Goto++ in APT to slew to NGC 7380 (Wizard Nebula), I set PHD2 off guiding and then I had my first issue; my laptop would not connect to my Lyn Astro dew controller so I manually set the temperature to quite low as it wasn't too damp at that time. So I started capturing 5 minute subs went inside and remoted into my astro laptop from my main laptop to check how it was going, all appeared good. I recently set up a Rpi NAS at home so I'm able to transfer data to it and then to my other laptop on the go, so after I'd got a few subs I opened them in PI to check the quality, they looked ok to me. after about an hour PHD2 started binging a lost star warning so I went outside and the clouds were starting to cover the sky, I then took loads of flat frames using my main laptop, Notepad and 3 sheets of white paper and decided to take some more darks in case it cleared. I then set about trying to process the 9 subs I'd managed to capture with the 200 flat frames the master bias and dark frames I'd created earlier. Despite the lack of subs I'm quite pleased with the result, I have done a quick Histogram stretch, and the knowledge I have gained, I'm definately going to purchase PI when I can afford it. So this morning I thought I'd sort out the issue with the connection to the Lynx Astro dew controller, you won't believe it, my Astro Laptop will not turn on, it's been playing up for a while I suspect the battery has died. So just when I thought I was getting on top of this frustrating hobby I get another spanner in the works. So do I gamble and order a new battery then discover it is the laptop that has failed, do I set up another old laptop I have and hope it will be ok, do I set up my Rpi3 with Indigo or do I buy a mini PC as I know my way around windows? Anyway here's the calibrated stacked image as it is in PI with a quick stretch.
My Lynx Astro power cable arrived today and the skies were clear so I thought I would grab the chance to try it out. Unfortunately it clouded over before I got a real chance of getting any decent data. However I thought I would get something useful out of the evening and do a quick review of the cable. As with many items, the packaging is usually a good indicator of the quality of what lies within. For the Lynx power cable there was no zip seal plastic bag, but a sealed padded bubble wrap bag with the Lynx Astro logo on it. OK, its only a bag but it shows that Lynx seem to be taking great pride in their products. Opening the bag revealed a 5m long cable with a standard 12v, 5A fused plug and a 5.5 x 2.1 centre positive jack on the other end. Although this is intended, and sold for use with a SkyWatcher HEQ5 and similar mount. However I wanted to use this for powering my Atik 314L+ and knew the jack was compatible. Comparing the cable with the original power cable the difference is significant to say the least. You can see that this is a seriously beefed up cable compared to the OEM one. The plugs have plenty of strong strain relief and are very snug and secure, certainly no fear of the cable wearing at the plug and causing a weak connection. Fitting the cable into the camera was a very reassuringly tight (but not too tight) fit and with the strange angles the camera can get into I certainly did not feel like it would come loose of its own accord. Later measuring the dimensions of the plug it showed that is at the upper end of the tolerance for the socket (at around 5.7mm). Something that I think Lynx Astro have done deliberately to reduce the chance of cables coming loose on mounts which is often a problem with that type of socket. The silicone cable is soft and very pliable (unlike the original cable that I had) and it hung in smooth curves with no signs of kinks etc. With a few slews of the telescope you could see that the cable easily rolled over the legs of the tripod, reducing cable drag. The temperatures did not get below zero so no frost etc. But its obvious that this cable is going to remain very flexible down to silly temperatures. Out of curiosity I did actually measure the resistance of the cable to compare it to the original one that I was using. With my cheap multi-meter (so it's not the most scientific or accurate analysis), it turned out to have around 0.1Ω resistance, 0.5Ω less resistance than the OEM cable. OK, its not a lot but when you are running on battery and want the strongest, cleanest power to your mount or in my case camera, every little bit helps. The only criticism that I can really point to the cable is that the orange cable might not be to everyone's 'cup of tea', but in the pitch black (light pollution aside) it doesn't really matter what colour it is. The orange does help you spot it more easily compared to black cables in the dim red light of your head torch, hopefully helping in reducing any trip accidents if you do need to trail your power lead away from the mount. I do hope that they launch a version that is compatible with the SkyWatcher AZ-EQ6 GT. Whilst the connector is not subject to the accidental power disconnection issues, the quality of the OEM cable is not the best, especially when compared to the Lynx Astro power cable. Hope you find this interesting/helpful, let me know your thoughts, especially if you have use this cable too.
