The 6th January was clear and still and so at last a good night for imaging (not perfect as Moon was still waning).
My 8" SW 200P Reflector was wanting to be used and so it was carefully mounted onto the HEQ5 and payload maxed out with the imaging train.
Yeah I know - this combination is a big ask for the job (but an EQ6 is beyond me at the moment!). Anyway with careful balancing and hardly any wind it was worth trying!
Nebula were best targets and again new ones for me.
These were the Bubble Nebula, Cave Nebula and Monkey Head Nebula. The Optolong L-eNhance Dual Narrowband Filter was used for all images.
Usual calibration frames and dithered instead of Dark's. Other 'Astro Stuff' is in my signature.
Any constructive criticism's welcome.
Bubble Nebula (Sharpless 162) 15x240secs (1 hour of data).
Cave Nebula (Sh2-155) 7x240secs & 23x300secs (2hrs 23 mins).
Monkey Head Nebula (NGC 2174) 44x240secs (just under 3hrs).
Hi all, just getting straight to the point.
Just got a Rasp Pi 400 (equivalent to Pi4-4GB), and looking to get into guiding through this as it's obviously a popular (and successful) technique.
Plan is to have the RPi as mini computer at home, running it with RaspPiOS (supplied on µSD with the full kit), then use it with a SECOND micro SD card for astro - I figure having another SD to run Astroberry (as on SGL) may ignore any issues with the family using the pi for other stuff in the house, giving a stand-alone 'computer' as the OS and files would be available on different SD's.
From this point, I'd setup as follows:
Connect the RPi directly via USB to the mount (it's the newer SW-AZ-EQ6Pro with the USB-B port on the mount)
Guidescope (240mm f/4) with T7C (equivalent to ZWO Mini) again USB-B direct to RPi
Nikon DSLR (either on telescope or using camera lenses) connected to RPi via Nikon USB (using the 3 USB points on the RPi-400) to control capture and later using this for plate-solving (but that's not for just right now!)
I don't spy any flaws in the plan, it's just going to be a matter of testing and setting things up hoping to follow the guide for Astroberry as linked to SGL below...
Or is there an alternative OS? From brief reading, Astroberry includes KStars & PHD2 which is what I've got for use on the macbook (although not used in earnest as it doesn't appear to like the cold too much!)
What about guiding software - I know KStars comes with it's own, and can run PHD2 from within, with PHD2 being the industry standard (and simplest?) to use?
Control will then be sitting in the warm via OS-X, which seems to be again a common technique as I've had posts on my other questions about this!
Just thinking how this setup would compare to normal astrophotography setups. Imagine a Nikon coolpix p1000 on an equatorial mount. Has anyone done that yet?
As I saw in the YouTube videos about the camera, it has absolutely no chromatic aberration, so I assume it's got apochromatic lens. It's magnification is extremely good (125x with 16MP sensor). The aperture is quite small tho compared to many different refractors available.
So what do you think about the idea: astrophotography with a Nikon?
Hi, I've got a Skywatcher Heritage 130p reflector, and if i insert anything less than 10mm eyepiece, the image won't get crisp. I guess it's normal, but as I'm very new to astronomy, I'd like to know what the sharpness depends on exactly.
Is that the focal length (how fast the telescope is? ) or the size of the mirror and how much light it gathers? Or both affect it the same way?
Are things the same with refractors in this regard? Thanks.
I have for sale my Skywatcher Startravel 120. Objective lens 120mm; Focal length . It is in excellent condition, clean and only very minor marks. Clean optics, no fungus. The focusser is the original one and works smoothly; 1.25" and 2" adaptors. With both caps.
A very good starter scope, or good as a portable scope.
Included accessories: red dot finder; 90 degree star diagonal; 10mm & 25mm EPs; mobile phone adaptor. All in as new condition.
Please don't ask me to split this package.
