M101 Pinwheel Galaxy 130SLT with nexstar mount D3200 (unmodified) 93x25s @ 800ISO 20 Darks/Bias/Flats Processed in DSS and Startools Had a lot of trouble getting down the noise and properly exposing the galaxy but thats probably due to the lack of exposure time Once I get my new setup, I'll properly try getting this, minus the noise and coma The Hi-res flikr link is here if anyone wants to have a go at getting a little more out of it https://www.flickr.com/photos/129093386@N05/43778258422/in/dateposted-public/ Matt Autosave00444.tiff

If you don't mind me asking, what do the axes represent?

Celestron 130SLT, Mirror moved 2 inches up the OTA, Nikon D3200 Took this just last night. It was clear enough for me to stay out there for a couple of hours. This time I took 85 lights @ 15 seconds, 800 ISO, 15 dark's and 20 offset frames totalling for about 20 minutes exposure Stacked them in deepskystacker and processed in startools, although unfortunately I couldn't save the file due to me not having the full licence. I've just ordered an intervalometer so I don't have to press my quick release shutter every time. Just one question: When the camera takes the 15 second exposure, it will take another 15 seconds for me to be able to press the shutter again. Is this due to the camera processing and is there anyway to cut that time down? Thanks all, Matt

Yes! But unfortunately my SD decided to corrupt the pictures and I wasn't able to retrieve them and had to format, so on that respect I can't. But I'll be sure to go somewhere where there isn't a giant light outside my house and try to get at least 20 minutes worth of data. Since I've done this mod, after having a go at orion, I'm planning to do pleiades and see if I can get the reflection nebula

M42 Orion Nebula Celestron 130SLT Mirror moved 2 inches up the OTA (To achieve prime focus without barlow) Very light polluted town (Literally a giant sodium light right outside my house) 13 lights, 10 darks @1600 ISO, 15 secs. 3 minutes exposure in total Stacked in DSS and edited in PixInsight Only was able to it for a short time because the clouds piled in and I wanted to test out after I extended the mirror

I was wondering what exposure time and iso I should use to capture the Orion Nebula. I have a Celestron 130SLT and a Nikon D3200. I know that this isn't necessarily the best, especially for astrophotography but I did give it a go before and I want to try and improve on the results that i have right now. Here's an example: Thanks, Matt P.S I took 19 light frames and stacked them on autostakkert and did some things in photoshop
