Question about framing new objects - Forums

Topic starter

Jul 26, 2022

I have been using APT and Stellarium from the get-go and I have never had a problem with the objects I have imaged (which is very few) They are all visible within the program so after plate solving and syncing the scope I can see how my framing is going to be for the most part. Now I am interested in shooting a couple different objects that don't show up in Stellarium. For example I had LDN 1251 and sh2-115 on my list of things to do. When viewing these in Stellarium they are not visible. While LDN 1251 may be a little easier to frame I know sh2-115 will be very tricky just using stars as reference for the framing I want.

So my question is… Do I finally have to say good bye to APT and Stellarium? Is SGP the answer to my problems? Or am I missing something here?

Maybe it is worth to have a look into N.I.N.A, even so you might only use it for framing but I like the combination of Stellarium to go to the object then frame in N.I.N.A.

You can easily grab the values and proceed somewhere else or, as I would personally recommend, have a closer look into N.I.N.A and stay 😉

I will have to take a look into N.I.N.A just to see if it's a better option, thank you.

I did just find out how to use the DSS in Stellarium which definitely helps for these particular objects.

I'm not sure I get your issue ... you can tell APT to point your scope at any target in the sky and can platesolve. You just need the object's co-ordinates which are easily available on the internet. You can either enter these in Stellarium or in APT.

What exactly is your issue?

I have never imaged a target by using it's coordinates before. In Stellarium I have just typed it in the search bar and framed accordingly using stars very close to my target. So now when I went to see LDN 1251 to plan my framing there is literally nothing to see, just stars.

I have now used the coordinates out of Telescopius and entered them into Stellarium to get the exact framing I want. I will be doing this from now on. Thank you, sorry I am a noob still.

I'm just a big fan of Stellarium and APT ... they work really well for me and as such I have seen no need to move to Nina as yet. i.e. If it works well, then why change it?

Hey Andy,

So I have recently went out using this method with the coordinates. When I framed LDN 1251 it worked great! I had no issues whatsoever. So I went out to image sh2-115 on Saturday and when I plugged in the coordinates to Stellarium it was not the same as Telescopious. Even the camera angle I had was not the same when viewed in Stellarium. Any suggestions as to why this could be happening on this particular target and not another? I have included both programs with the same coordinates and camera angle so you can see the difference.

Your RA and Dec differ by several arcminutes, so it seems you didn't enter the proper coordinates. In addition you have set a rotation of 125 degrees for your scope which will change the orientation. Stellarium remembers the orientation of scopes between sessions, so you have to reset it by clicking on "0°" on occasion. In addition the orientation of the frame in the sky depends on the time, so you have to set both applications to the same time if you want to compare. If you compare the orientation of 56cyg / 57cyg in the lower right of the frame you will realize that there is quite some rotiation between the two images - they definitely depict different times.
