Tonight I managed to finish processing one more target.

Thank you. I started with gain 16 that I've been using for a while and I decided to drop it down to 11 in the hope that I will not get fat stars in my photos. The difference wasn't that great and in the end I decided to drop the exposure too. I'm still learning what's best for this camera. I ordered a baader ultra-narrowband set which I'm hoping it will help even more in reducing the star sizes. I only got the 3.5nm Ha and 4.5nm Sii and tonight I put them in my filterwheel. The Oiii is not in stock anywhere. Emil

Slowly, I'm catching up with processing my finished targets.

I don't know if it's any different from the eq3 GoTo Pro that I have but at some point when I started my imaging session I didn't realise I wasn't guiding and I shot a few 300sec before I realised I wasn't guiding. I checked the subs and I was very pleasantly surprised to see the stars looked very good. I was using my TS65 at 420mm focal lenght with my canon 700d. A lot of people are telling me that I must have the best eq3 in the world but I think that very good polar alignment and balancing can get you far with this little mount. I can easily do 600sec guided with the TS65 and my ASI294MC but the setup is quite light. Here's a 4 panel mosaic that I did with this combination. Emil

Amazing!

Thanks Adam. If used properly, the StarSpike Pro can do a really good job producing spikes that don't really give you the fake impression. I had newtonians for quite a while and I'm trying to replicate the real spikes I was getting with them. Emil.

I've always been afraid of this target because of the big bright Navi and I had quite a few failed attempts before I got to this result. For some reason the Altair Tri-Band filter is changing the colour of the very bright blue stars into red and also making a nasty red halo around them. I had to play with the yCas star to make it blue as it should be. I added the artificial spikes because I thought they would give a nice overall effect to the photo.

This year has been the best year so far in terms of astrophotography and it's not finished. Still have the Wizard and Fish head nebulae to process but until then I thought of making a little collage of some of my best from this year. I hope you like it. 🙂 Emil

Due to moving house recently, my finished targets started to pile up. I finally managed to process one of them. The butterfly in the Sadr region. 41x600sec Ha 34x300sec and 19x600sec Oiii 19x300sec and 20x600sec Sii All shot with my QHY183M on the AT106 telescope at 690mm focal lenght. Stacked in pixinsight, processed in photoshop. I hope you like it Full resolution here: https://www.astrobin.com/y65nny/0/ Emil

Thank you Bryan Thanks Alan. I hope you feel better soon. You can always try a mosaic if it doesn't fit in one frame. Thank you. I love the colour too. Initially I tried to do everything in APP but when it got to the stacking stage it was running out of memory. I then decided to save the calibrated, registered and normalized files and throw them in pixinsight. Emil

Last week I had another go at Andromeda withe the ASI294MC and seeing how much data I have from last year when I shot it with a dslr and the Qhy10, I decided to put them all together to see what comes out of it. It's a combination of 1min, 2min, 4min, 5min, 10min and 15min exposures bringing the total integration time to 22 hours and 11 minutes. There are a few problems with some of the stars and I think it's because I stacked all the exposure lenghts in one go rather than doing it separately. Another one is the artefacts that I got from the dslr subs. They are noticeable on the top right of the galaxy. Overall I'm pretty pleased with it. So here it is, Andromeda in HaRGB. Emil

A few night ago we had one more clear night and I managed to finish what I wanted for this 4 panel mosaic. This Tri-Band filter changed my OSC imaging so much, I absolutely love it in combination with the ASI294MC Pro. As per my my other mosaics, I used the TS65 Quad on the EQ3 Pro mount. Captured with SGP, guided with PHD2. 25x600sec for 3 of the panels and 30x600sec for the Tadpoles panel. Stacked in APP and Processed in Photoshop. Emil

Wow, so much dust, I love it. Emil

Thank you guys, I'm really glad you like it. I used my eq6. Emil

I managed to finish processing one more target. I'm sometimes grateful that we have some cloudy weather because I was starting to feel that I will never manage to finish processing my data 😀 Well as you all probably know this is the Elephant's Trunk nebula. I started shooting it quite a while ago, in April, with a 130PDS and I continued with the AT106 last month and this month. I managed to gather a total of 19 hours and 40 minutes worth of data. 76x300sec Ha with the 130pds and the rest of 9x600sec Ha, 36x600 Oiii and 35x600sec Sii with the AT106 I hope you like it. CC most welcome Emil

Hi guys. Is it possible to set a certain start and stop time for each target? Last time I used it I couldn't find this option and I went back to sgp. My view is wuite restricted and I wanna stop one target before it goes behind the trees. Also, does NINA remember the last focus position for each filter? Emil

I tried on the partially stretched Ha stack and this is my result. My stars are very fat even in the Ha stack and I had, still have quite a few residues. How do you clean them. I ran the Spot Healing brush tool on most of them. Is there any other way to make them blend with the surrounding area? I'm not really a fan of starless but I really want small stars in my SHO photos and if this will help me do it , so be it. Emil

Thank you so much. I have a feeling that it will work. I ve done it quickly on a partially stretched RGB photo and I like what I see. Can't wait to try it on the individual Ha, Sii and Oiii Emil

Thanks. I need to have a look at those light vortex tutorials.

It is indeed 5000 pixels wide. The qhy183m is a 20mp camera. I should probably bin the imaged 2x2 in pixinsight because unbinned the resolution of 0.72 "/pixel is a bit high for nebulas. Emil.

I have pixinsight that I can use but have no clue on how to use masks. I also have photoshop (Noel Carboni's astronomy tools, Annie's action pack, Noise ninja, Nick's filter pack with Dfine for noise reduction) where I do most of my processing.

Wow, this looks so good. I tried soooo many times the star removal but I never got a good result. I have no clue how you guys are doing it. 😢 I have the pixinsight starnet plugin, I have the standalone version too, Annie's action pack in Ps, Straton. Tried them all and I just can't get a good result. Would you mind sharing how you are doing it please, do you do it on a stretched or unstretched photo? At what point in the process do you do it? And lately I get an error when trying the pix plugin, Check point not found or something like that. Emil

Hello again. Last night I was up a bit later than usual to try and finish my cave nebula. I think there's a lot I need to learn on using the noise reduction properly, on reducing the big fat stars properly and controlling the halos. Looks good when I look at it from far away or on my phone 😂 but when you zoom in it's 😱. Am I crazy? I would really appreciate if you guys would tell me when in the process you use the noise reduction and what noise reduction techniques you use. Thanks Emil

I was never drawn by this target but one night when I didn't know what to shoot I decided to try it and see what I get. I guess it's not too bad. 129x300sec and 8x600 sec Gain 200 Offset 10 Eq3 Pro TS65 quadruplet f6.5 imaging telescope ZWO ASI294MC PRO cooled at -15°C Altair 2" TriBand filter Qhy5 guide camera 9x50 finder-guider Emil

I gathered some more data and reprocessed it. This is what I came up with. now, 40x600sec Ha, 32x600sec Oiii and 32x600sec Sii.
