New Laptop and Orion Magnificent Mini Autoguider. Phew!

It's been a while since I posted. Increased age related sensitivity to winter temps and a bit of laziness around imaging galaxies during galaxy season is partly to blame. I'll do better next fall and winter. Also my aging Acer laptop while usable needs a new keyboard which, according to a local tech guy cannot be replaced. As a stop gap I acquired a $10 Bluetooth keyboard while shopping for a new computer. Also, the Acer is incompatible with Windows 11. 

After some research I opted for a Dell Inspiron 2 in 1 driven by an AMD Ryzen 7 8840Hs at 3.30 Ghz. It shows when in the time it takes to stack lunar images which is an order magnitude faster than the Acer it replaces. For the most part I'm no fan of Windows 11's look and feel or Microsoft's pushing and nudging users towards the Edge browser or obnoxious OneDrive. OneDrive almost caused the loss of my years of SharpCap images. Fortunately there are numerous tipsters providing advice on how to make Win11 less annoying. 

So why the Phew!? When it came time to install the auto-guider software I realized I didn't have the drivers for the Orion Autoguider. As you're likely aware Orion went out of business and PhD2 does not include the drivers. Well, much thanks to someone going by italic posting on Cloudynights  the drivers and installation software can be downloaded from here on archive.org. 

Over the last couple of nights I revisited some of my favorite targets, globular clusters, to give the Orion Autoguider a workout. With the current settings performance has been excellent. 

Setup: Celestron 8/AVX, Starizona 0.4x NightOwl FR, ASI294MC Pro, Orion Mini Autoguider. Imaging: SharpCap pro,  30x30s, 0C, 120 gain. Processing: Autostakkert! (stack averaging), GraXpert (stretching/gradient reduction), Paintshop Pro(image touchup)

So Begins Globular Cluster Season.

Globular clusters (GC) are some of my favorite targets for this time of the year with short spring and summer nights and the annoyance of daylight saving time. With sunsets around 2030 and astronomical twilight's around 2240 globulars can usually be acquired in less than 15 minutes making for productive nights of imaging. 

Why do I keep coming back to these low hanging fruits? I like to think I can improve on my past performance and take advantage very rare good seeing Northeast nights. Most of these targets are low in the southern sky making it challenging to image them with the denser more turbulent air and refraction.

A few recent examples appear below. All of these globulars were acquired from a favorite Harvard, MA darkish site with 15 x 30s subframes with a ASI294MC-Pro, Starizona Night Owl 0.4x focal reducer and Celestron 8 on an Advanced VX mount. 

While I call this Globular Cluster Season there are many more  open clusters favorably placed this time of the year. Look for images of those in up coming posts.
