I did this test image of M3 with my trusty old Ultima C8 and my new ASI-533MC-Pro camera.  I really like how the star colors came out.

 

60 x 10 seconds (10 minutes total exposure)

Playing with my 1985 Tak Epsilon 130 on EM-1 mount.  Shooting with an Olympus OMD EM5-ii.  This exposure is about 2 minutes with noise reduction on,  Reduced in size from original RAW format and jpeg compressed to fit here:

I got frequently asked (especially by friends and their kids wink.gif ...) how to take a Moon pic with a smartphone.

 

So I made a small video on youtube, using iPhone SE and my C5 Classic ... it's certainly nothing fancy in terms of "astro photography" ... yet somehow it's just great fun that you can get such a good result by using such simple means!

Here is one from last night using a Questar 3.5 and NexImage 5 camera. 

 

I got lucky with the GRS and transit going on. The weather was very, very cloudy and I barely had time to achieve good focus. It was brief as I only had time for two short captures before the clouds became too thick.

Digital Imaging, Slightly Older USB Cameras, & Windows 10  --  I've been going round & round with the hardware issues created when Microsoft finally complied with USB standards, which unfortunately caused problems with imagers like my 3 year old ASI120MC...

 

So... I found a NOS Panasonic ToughBook made for some DOD contract that must've fallen through.  It's a Windows 7 system, which should work well with all my cameras -- 3 planetary, & 1 DSO.  Should be here next week.  With all the other R/L Stuff going on, and Jupiter & Saturn in the soup, this wasn't a high priority, but as usual, Mars rising got me motivated.

Just an amazing photo of Jove Terry! It’s a real testament to the wonderful optics of the little Questar, paired with the skills of a very talented photogrqpher!

So... I found a NOS Panasonic ToughBook made for some DOD contract that must've fallen through.  It's a Windows 7 system, which should work well with all my cameras -- 3 planetary, & 1 DSO.  Should be here next week.  With all the other R/L Stuff going on, and Jupiter & Saturn in the soup, this wasn't a high priority, but as usual, Mars rising got me motivated.

There's a lot to be said for preserving some of these "old" computers and cameras.  Case in point:  I have several Firewire and USB machine vision cameras from Point Grey and Allied Vision Technologies that were state of the art just a few years ago.  And since most computers no longer have Firewire ports, I try to keep my old ones alive (but currently have adapters to use them on my 2016 Macbook Pro).  I also bought a license key for Astro IIDC when it was shut down 10 years ago, and I still run it on all my Macs.  But the best of all?  Many of these cameras turn up on ebay for silly-low prices.  Last week, I bought a Flea3 with the VGA chip and 9.9 micron pixels for $30, NOS sealed in the box.  I plan to use it as an e-finder with a c-mount lens.  My favorite Pt Grey camera, though, is a Flea2 1.3MP color camera with the 1/3" ccd, that I bought new from Point Grey for ~$800.  I've seen these for less than $200, again, often NOS.

 

I took this Mars image with the Flea2 through my 12.5" f/23 Classical Cassegrain 2 weekends ago.  The scope is an ATM, but the optics are classic 1990 from Ed Beck (Enterprise Optics).  The seeing wasn't great, maybe a 5/10, and it was windy. I'm hoping to do better when I can get back to Cosmic Acres in a few weeks.  Acquired and processed with AstroIIDC on my 2016 Macbook Pro.  Exposures were 33 milliseconds.  Stacked a couple thousand out of 10,000 frame video, 16-bits per color channel.

I've been getting my feet wet with my Nikon D70 DSLR coupled to my Celestron

Celestar Deluxe 8 inch.

You can really see from my results so far I don't have a single photographic bone

in my body.

I dove right in without self-educating myself, that's not going to work. There's a

reason the D70 owners manual is 206 pages.

I just got a new smart phone [moto G8], and based on my DPAC pix... I'm not gonna even attempt holding it up to an eyepiece...

 

I hate that I ditched my ancient ThinkPad, but this ToughBook is weatherized (dew-resistant) & meets DOD shock / impact standards.  BUT... the screen is small -- 9" diagonal, so I'll have to remember to wear my reading glasses while focusing.  If it doesn't work, I'll buy a used 35mm SLR and go back to the analog daze...

There are a lot of really nice photo's in this topic.

 

I am not yet at this same level, but here is my best photo to date. It was captured through a Tanzutsu made Jason Model 313 Discoverer EQ 60x910, and with a single shot from a computer USB Logitech Quickcam Pro 4000 web cam in the standard windows10 photo application on April 5th of this year.

 

3.jpg

 

I painted all the internals of the scope including the focusser with black chalkboard paint, and also painted the outside rims of the objective lenses. I don't know if any of this made a difference at all, but I have always been happy with the performance of this scope.

 

"Most here do not even like Tanzutsu's", when compared to other Japanese manufactured alternatives. I think I just had some luck on a good night, as I have never beat the detail in this photo when attempting a similar shot from my other scopes.

Finally!  My work-at-home day is done.  My ToughBook was delivered this morning:  Small, heavy, built like a brick, and... unloaded -- as in No Windows -- but with a stack of CDs (OS, drivers, applications, & extras).  Got the bare-bones stuff done this morning -- Windows 7 + hardware drivers.  Since 1500... it's been downloading & installing umpteen Microsoft updates.  Maybe it'll be ready for Camera Testing tomorrow...

 

Here's a Big Difference between Now and Back Then when making astro-photos:  Now, you have to worry about your camera, computer, and/or software becoming obsolete -- sometimes in just a few years.  Back Then, so long as your 35mm SLR worked, you were good to go.  Yes, FILM went the way of Betamax, but that took decades...  (No, film wasn't a better option, but it was dependable.)

We need to head out to our property in Milford, Utah, to close up the house for the winter.  I think I need to let Tinky or my 1975 C-8 out of their boxes for some serious planetary imaging this trip, since the moon is fat and lighting up the night sky this next week.

My first attempt of imaging with my RV-6 last night.  I used an ASI120MC and a 2x TeleVue Barlow.

May be ok for some deepsky, planets will be harder, it's a 6mp APS sensor DSLR so coupled to the old C8 doesn't give much image scale/resolution so you need strong barlow'ing or eyepiece projection.
