I've been trying to image a couple of galaxies per night, one pre and one post flip. On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data.
Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
Mount: Mesu e200
Guiding: ZWO OAGv2, 290MM, PHD2
Software: APT for capture, APP and PS for processing
I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before. I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time. I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
I developed an Android app - Telescope.Touch - capable of connecting and controlling INDI/INDIGO devices, for those of you who use Raspberry/Astroberry/StellarMate.
It's really powerful, and a lot of new features are in the works.
Mobile planetarium derived from the Sky Map project Mount and focuser controller with directional pads and speed controls Receive images from INDI CCDs Database full of objects to which you can point the telescope directly from the app INDI control panel compatible with every device Aladin Sky Atlas preview and altitude graphs Astronomy utilities: polaris hour angle, compass, red flashlight Languages: English, Italian and French. Sky maps are translated in almost every language. It is available on Google Play: https://play.google.com/store/apps/details?id=io.github.marcocipriani01.telescopetouch
A Pro version is also available, mainly to support the app's development: https://play.google.com/store/apps/details?id=io.github.marcocipriani01.telescopetouchpro
I hope you enjoy it! I'm open to feedback and improvements!
So I've finally gotten round to setting up APT and Sterallium (via ASCOM) on my laptop for controlling my mount EQM 35 pro. (I got PHD2 working on it a while back). I followed a tutorial on youtbe about doing this using simulators in Sterallium, when doing this pressing control + 1 on the keyboard moves the simulated telescope and everything seems to update in ATP and work fine.
The (small) problem I'm having is when i successful connect my own mount in Sterallium (after doing the same in APT) I click on an area and then press the short cut Ctrl + 1, nothing happens, my yellow telescope icon doesn't move to the location, but when I do it in APT, sterallium obviously updates to show the new position.
Any idea why the short cut in Sterallium isn't working when connected to my mount?
For what has seemed like forever, the clouds finally parted late last night and the Orion constellation was very clear from my balcony.
I had a brief window of opportunity earlier this week and had difficulty focusing on stars at all using my DSLR (Canon 450D) and APT.
Last night was a breakthrough; I was able to capture starlight in APT liveview and even bring the stars into (significantly better) focus!
I now face my next challenge; I am unable to focus sharply on any of the stars. Using my telescopes focusing wheel I seem to get only blurry spots of light coming through, despite very carefully adjusting the wheel for quite some time.
At the risk of embarrassing myself, I've attached the images of Rigel and Betelgeuse I captured last night (on both long and short exposures, details of ISO and exposure are detailed in the image titles). This is as sharp as I can them.
Is there anyway I can fine tune the focus? I've seen AP videos on Youtube where jam jar lids have been glued to the focus wheel or motorized focusers attached. Are these gimmicky or do they make a significant difference?
I should mention that I don't yet have a tracking mount: I've eyed the Skywatcher AZ-GTI wi-fi as good candidate for my first meaningful mount (with the EQ wedge coming shortly after). Having emailed a number of retailers it seems these are in very short supply, here's hoping stock replenishes post-Christmas! I think this will let me get to grips with the equipment I have right now, definitely would like to get a sharper image, even if I'm only capturing star trails.
to capture the images shown below I used:
- Celestron 100AZ (100mm Aperture, 660mm focal length)
- Canon 450d
- Barlow lens x2 (Celestron)
- APT (connected DSLR directly to laptop via USB)
- Stock Celestron Alt-Az Mount
All the best.
