IamLost

Using my Evostar ED80 pro and a canon 700d with no guiding, I managed to get my first complete DSO. 182x30” subs at ISO 1600 15 flats 15 darks 20 bias/offset stacked in DSS edited on PixInsight total exposure time of ~ 1 hour 30 minutes There is quite a lot of noise and some of the large stars have trailing due to imperfect polar alignment, but overall I was glad with how it turned out. 611C6392-0F43-472C-B74F-B8CE80984379.tiff

Alright I will try that. Thanks for the help

The camera I’m using is a Canon 700D. I definitely used RAW for all images I took and kept the image quality the same so I have no idea why the file is a different size

Yesterday when I went to stack my images after a long session, I got an error message from DSS saying that some of the files were incompatible due to size or colour channel. I looked at all of them and the only different files were the bias frames which had a different colour Channel and a smaller image width and height for some reason. I unchecked the bias files and the processing worked so I was wondering why I couldn’t use the bias files and how to use them like I had done so previously without doing anything differently.

Ok thanks

I have an EQ5 Mount with an RA motor drive so it doesn’t automatically allign

Ok thanks for letting me know. What is drift alignment exactly? I’ve read a bit about it but I don’t fully understand it.

Basically Polaris is blocked by my house so I cannot use it to align and I was wondering whether or not there is a way to align without seeing Polaris. I’d like to do some imaging so it would have to be aligned well enough that there won’t be noticeable trails. Thanks!

Thanks for the help

I’m not sure because it hasn’t been delivered yet but it may come with a battery box. Do you know what kind of batteries I will need to power it?

What is the best thing I can use to power my EQ5 RA motor and what kind of supply do I need (what voltage and current)? Also, would a normal laptop charger work as long as it has the correct output? Thanks.

Thanks a lot for the info I didn’t know you could take images like that with only 1 second exposures!

The reason why I’m asking is because I can’t really take any exposures longer than 0.5 seconds because I don’t have an RA motor drive yet, but when I get one I will compare them.

Basically, I was wondering if there would be a difference in detail between, for example, one 15 minute exposure and 1800 0.5 second exposures.

Thanks for the advice, and also the reason I took a photo of my screen was because my login details for this site are saved on my phone so I posted this on my phone
