Thank you very much for the lovely comments. Somebody actually told me that I can pull more out of it and he showed me his attempt with a RASA 8, under dark skies and dedicated astro camera. My intention was always to reveal only as much as I could without making a mess out of it and I'm very happy with it as it is, especially the 8 spikes 😁 I never thought of stacking everything on it before and it worked out very nice with the camera angle both at 90 and 0 degrees. 🙂 Emil

This name is the first name of a deep sky object that I ever heard. I heard it from my father talking to a friend when I was a child and always wondered what it was. This is why I love to call it The Great Orion Nebula 😁 Emil

So, for the last few days I kept thinking that Orion is coming back in the scene and I was wondering if I should shoot it again with the 6" RC and QHY163M. Because of that I decided to stack all the data I had on it from 2017 and 2018 to see what result I get from it and if it's the result is good enough I can skip it this year too and concentrate my imaging time on something else. I only have 4 hours of data and maybe adding some Ha to it would bring some benefits, I don't know, but I'm really pleased with what I got from it and I just might skip it this year too, what do you think?

I have no idea. I emailed them a couple of times but they didn't even bother to reply. I was actually thinking of selling the Ha and Sii ultra-narrowband and getting the Antlia 3.5nm set but I'm still not very convinced they are better and on top of that I would lose out a lot from selling them. Emil

Thank you. Looking forward for next year to add some sii to it and maybe some more Oiii too. Maybe until then Baader will go back to manufacturing the ultra-narrowband oiii for which I paid in December last year and I still don't have it. Emil

Earlier in the year when my planned north america mosaic was a bit too low, I managed to squeeze in some data on the Eagle nebula. I was planning to make it SHO but cygnus was getting higher in the sky and I had to stop shooting the eagle and concentrate on the mosaic. Last night I had a look at the data and had a go at it even though I would've loved to have a bit more Oiii. So this is 69x300sec Ha with the ASI294MC and AT106LE, 22x300sec Ha and 39x300sec Oiii with the QHY183M and TS65Q Full resolution here https://www.astrobin.com/full/nc8rz1/0/ Emil

Hello Tareq. Sorry to bring this thread back up again but I just got a used qhycfw2-m us with 7x36mm carousel but I replaced it with a new 8x1.25" carousel. I have it connected to my qhy163m qith the 4 pin cable, it connects properly but sometimes it doesn't go to the correct filter when I tell it to in sgp or it even spins continuously and I have to unplug it and plug it in again. Are you still using a qhy163m with the qhycfw2-m us? If so how are you connecting it? Thanks Emil

Thank you! It's really 75 hours as I was shooting with both my telescopes at the same time. 😁 Emil

Thank you guys! I'm really glad you like it! I nearly stopped it a few times, I thought it will never end but I'm happy I didn't. 😁 It was chosen as a top pick on astrobin too. My first one ever. 🥳🥳 Hopefully not the last. 😁 Emil

Thank you! 😊 Emil

This is my biggest ever project, something I never thought I was gonna be able to do. A 15 panel mosaic of the North America nebula region shot with both my setups at the same time. I used my ASI294MC Pro with the AT106 to shoot Tri-band and Ha and my QHY183M on the TS65Q to shoot Ha and Oiii so the total integration time is 150 hours but the imaging time is half of that. Before the mosaic I have the cameras swapped between the 2 scopes but I changed them over for a closer field of view and pixel scale between the 2. I started shooting the mosaic in April this year and I finished it last month. Using APP, I extracted the Ha shot with the 294 and Ha filter and the Ha and Oiii shot with the tri-band. After that I stacked all the Ha and Oiii for each panel and blended them all in APP. I used pixinsight Starnet++ to remove the stars from both Ha and Oiii, I blended them into the HOO image and worked on it until I was ready to put the stars back. I'm really pleased with the result, it might not be perfect but I can say that it's my best astro image so far. I hope you like it too.

A few weeks ago I thought of going back to a target that I loved shooting. I already had 43x300sec and 43x600sec shot in 2018 with the TS65 and my old canon 600d but I thought that adding some more data with the ASI294MC would make it even nicer. I ended up shooting 159x300sec bringing the total integration time to 24 hours. I think it looks pretty good, some of the blue stars have yellow core but I can live with that Thanks for looking, Emil

I think I will put the camera on the TS65 to see if it's the RC causing it or the filters being too far from the sensor.

What on earth is going on? Covering the gap helped a bit but the flats are still not fully correcting. I shot the flats after 1am when it was dark outside, not street lights on and no other lights around to make sure there's no leak but I still get it. This is the master flat from last night And this is how the calibrated lights stack looks like I shot some sky flats this morning but those didn't work either, they actually made it worse

Hopefully I'll be able to see some stars tonight and shoot a few lights and new flats to see if covering the gap did the trick. 🤞🤞🤞

Thank for the reply Olly I don't use any red lights or anything but I do keem my laptop close to the mount when shooting the flats. I usually control everything from inside but when shooting flats, I use my laptop outside. It's possible that some light from the screen but not highly possible as the screen is usually facing the opposite direction. Other than that I don't know what light it might be. I have a street light right at the end of my garden and to keep the telescopes in the shade I open a large parasol during the night. The lights are turned off between 1 and 5am. I have some blackboard paint from the time I had a newtonian and used it to paint the back of the mirrors and the focuser. Would that work? Emil

Thanks John. My back garden is fairly bright so it might be a light leak. I covered the gap on the tilt plate and shot one sky flat to see if there's an improvement and the circle I was taking about is nearly gone, if not completely gone.

@johnrt, did you ever have this problem? Emil

I wonder if it might be a light leak from the tilt plate

the stack is exactly what came out of APP, with autostretch applied in pixinsight and saved as png, nothing else. yes, sgp did a meridian flip during the night

I have no clue what's going on, I even opened the filterwheel to check the red filter and it's all good

I have SGP set to take 10 of each throughout the night to be sure I have enough of each at the end of the night so if there was a leak when I shot the red, it should've been there when I shot the other ones too

it does seem wrong indeed. culd it be that I shot the darks with the camera in the fridge, in complete darkness and the flat darls with camera on the scope covered, outside in the garden?
