TerryMcK Posted December 2, 2021 Share Posted December 2, 2021 Upload the image to http://nova.astrometry.net/upload and it will tell you what it is Quote Link to comment Share on other sites More sharing options...
Mirrorgirl Posted December 2, 2021 Author Share Posted December 2, 2021 Hi there It says I have M33 the triangular pinwheel..I don't know how true this is maybe you guys could help me find out what I have located Thanks guys Quote Link to comment Share on other sites More sharing options...
Mirrorgirl Posted December 2, 2021 Author Share Posted December 2, 2021 Not being funny but four people have downloaded my master image so it must be something? Quote Link to comment Share on other sites More sharing options...

You have something, but I don't see any galaxy. I took it into Pixinsight, and stretched the image fully. If you had M33 it would show up at least the core. How are you locating your targets, with the handset, or with platesolve? Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted December 2, 2021 Share Posted December 2, 2021 I uploaded the image to astrometry.net and it came up with the coordinates of this Calibration Center (RA, Dec): (28.237, 29.516) Center (RA, hms): 01h 52m 56.773s Center (Dec, dms): +29° 30' 57.319" Size: 2.17 x 2.9 deg Radius: 1.810 deg Pixel scale: 8.7 arcsec/pixel Orientation: Up is 66.9 degrees E of N Then I put the coordinates into Stellarium You can see the crosshairs showing where the coordinates are quite a bit south of Andromeda. Clicking on the crosshairs shows what is at the coordinates Zooming in reveals this So you are looking at the star Mothallah. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted December 2, 2021 Share Posted December 2, 2021 BTW don't take any notice of the red rectangle as that is how my sensor is relative to the sky. Your image is centred on that star not Andromeda nor even M33 Quote Link to comment Share on other sites More sharing options...

With the hand set but it's never exactly on target I have to move it left to right and up and down cause it's always off I don't no why Quote Link to comment Share on other sites More sharing options...

Your mount needs to be level. Your polar alignment accurate, then you need a 3 star alignment using your handset, and you will still not be centred on your target. A far more precise method is using Platesolve in a programme like APT or Nina. 1 Quote Link to comment Share on other sites More sharing options...

Thanks v You don't have to guide, but guiding will allow for longer exposures. Good polar alignment will allow you to take unguided images for around 30s. APT is probably the better option for you, it also allows you to control your DSLR and focus it. Plus it will platesolve your target, ensuring accuracy every time. 1 Quote Link to comment Share on other sites More sharing options...
