I am hoping someone might be able to help with a possible way to shoot dark and bias frames on a DSLR (canon 700D) without the need to cover the scope or camera, ideally using APT scripts
My thinking is that the camera, has a noise reduction mode where it will take the light shot, then with the shutter closed it will take a dark frame and subtract it from the light. So could you take a series of dark frames on ATP and lock the shutter down?
If anyone knows I would love to know. Would be great to automate the lights, park the scope and have it run darks and bias, without the need to go out to it and cap up at 3.-4 in the morn
Hi, my current telescope is Celestron ExploraScope 70AZ, thinking upgrade to skywatcher heritage 130P(came with 25mm ajd 10mm EP) , if i do, can i use the eyepiece (4mm) and x3 barlow from my old celestron on the 130P?
One more question, i ordered a eyepiece camera Svbony SV105, i wonder what is magnification of this camera and how it work to change magnification.
Hello! I have a question on how can I mount my camera to my Sky-Watcher Starquest 130P telescope? I’ve watched so many videos about it and there’s so many different answers on what I need to do that. At the moment, I have 2x Barlow lens and a DSLR. I know that a T-ring is also necessary but is there anything more? Any help is highly appreciated, thanks! (I’m really new to telescopes and astrophotography in general so I hope I don’t say anything dumb)
I recently upgraded to a purpose made astro-camera (Atik Horizon Color). The learning curve has definitely been noticeable, but I cant figure a couple things out. For some reason the pictures are grey scale when using N.I.N.A. I have tried different binning and formats, but the image is always black and white.
If I use the ATIK software (Infinity,Dusk) there is an option for 'Color Binning', and that seems to have fixed it for those programs, but N.I.N.A doesn't seem to have that option (you can not select anything for binning, or select 1x1, 2x2 ect.). But what makes it weirder is that the preview is always color using N.I.N.A. I used a pinhole lens cover to take pictures of my computer screen and it always shows up as color images. However, if I take that exact image file that previews in color and move it to pixinsight, it is grey-scale.
Is this a binning thing, file format problem? At this point I am just confused, if the preview of the image is color shouldn't the image data be color as well?
So far all the problems I have had with this camera have just been simple things that were new to me, but this one is really throwing me for a loop. Thanks for any help.
I've attached a couple images. The first you can see the NINA preview is color, as well with the couple other I took in the bottom right. And the other in a photo of trying to color saturate the stretched image in Pixinsight, and it says that it cannot saturate a grey-scale image. I have tried this with Tif, Fits, and various binning types.
Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.
