A target that I wasn't intending to do this year but one night when I wasn't sure what to go for I thought of shooting a few subs and when seeing how a 5 minute sub looked like, I decided to go for it after all. Very happy with the result 😁 Eq3 Pro mount TS65 Quadruplet imaging telescope ZWO ASI294MC PRO Astronomik 6nm Ha clip in filter Altair 2" Tri-Band filter Qhy5 guide camera 9x50 finder-guider Software used: Eqmod, SGP, Stellarium with StellariumScope, PHD2, SharpCap for polar alignment Location: Back garden, Bushey, UK (Bortle 6) Date: 24.02.2020 to 04.04.2020 Total integration time: 12 hours and 40 minutes Calibrated and stacked in APP, processed in Pixinsight and Photoshop.

Yesterday I went back and reprocessed what I consider to be my first successful photo. It was shot 3 years ago in March 2017 The Leo Triplet Equipment used: Eq6 Pro Skywatcher explorer 200p, f5 newtonian Astromodified Canon 700D Astronomik CLS-CCD clip in filter Baader mpcc coma corrector Lacerta Mgen standalone autoguider TS09OAG off axis guider for EOS. Software used: Eqmod, APT, Stellarium with StellariumScope, Astrotortilla, Lacerta Autoguider PC app Location: Bushey, Bortle 6 Date:24 and 31.03.2017 The image is the result of photos taken during two imaging sessions with a total exposure time of 5 hours and 40 minutes and is composed of 15x300sec, 13x600sec and 9x900sec exposures all at ISO400 with 49 flat frames and 20 bias frames.

I found that too. All the galaxies were red when I started with it. I tried the photometric colour calibration in pixinsight but for some reason it couldn't solve the photo so I've done a star calibration in APP. Things started to look a bit better from there but I think there's a lot more that can be done with more data. Emil

This is the start of my Markarian's chain project, well, more than half way actually as I want to make the fainter stuff show up a bit nicer and also reduce the noise in the final stack. A few days ago I stacked what I gathered so far to see how it looks like and after adding the annotation in pixinsight I was shocked by the number of galaxies in the photo.

Thank you! I think the Tri-band filter helped a lot with the horrible light pollution coming from London. Emil

A target that I could never get right. I really like this year's attempt but I still feel it could use more data. Not easy, not easy at all when I have London in the direction that I'm shooting. If I'll still be alive at the end of the year 😂, I think I will add more to it but fir the time being I'm sharing with you what I have so far. I hope you like it.

Thank you guys, I'm glad you like it. Being in such a bad location for low Southern targets, the only thing I can do is push the integration time as far as I can. I guess it really paid off. The 3.5nm Ha filter helped a lot too. Can't wait to get the 4.5nm Oiii but who knows when that will happen. I've been waiting for it since the end of December. Emil

Last year in November we moved to a house in the same area but with the Southern view much better than the one we used to live before that. Knowing that I now have the chance to shoot some targets that I could never think of from the old house, I decided to push my limits and try a target that I wanted for a very long time. NGC2359 is passing the meridian above London at 25 degrees in altitude so this is a difficult target considering the circumstances. The photo is a bit noisy and I think that might be the London noise but I'm very happy with the result. AT106 with Qhy183m 115x300sec baader 3.5nm Ha filter 114x300sec baader 8.5nm Oiii filter I think it would've been much better with a 4.5nm Oiii filter but I'm still waiting for it as it seems that no one has it in stock. I hope you like it. Emil

It is belt modded, yes. I checked the balance again and on RA is very good in all positions but in DEC in some positions, the cables are pulling down the camera end. I adjusted it a bit more and it is a bit better but still not good enough.

I'll tick the correction bix on my next clear night. I noticed the star was saturated and I changed it after I took the photo. I usually let them run on their own and go to bed so I have to let PHD choose the guidestar. I was thinking it might be backlash but this only started recently. When I had it on the pier, the total RMS was 1" on bad nights and 0.5" - 0.6" on very good nights. I recently moved and now the mount is sitting on the tripod. It was good at the beginning but about a month ago it all started. I would make the mount east heavy but letting it run on its own because of my work commitments, after the flip it will be west heavy. That's why I try to balance it as good as I can.

Hi guys. I dont know what's going on but I think my mount has a problem. My guiding is always quite good (0.8" RMS) up to the meridian an flip. After the flip the DEC is starting to go crazy. I polar aligned, I don't know how many times, I balanced the scope the best I could but still nothing. Any idea what it might be by looking at my phd2 graph? 1st image is before the flip and second is after the flip. The mount is a hypertuned eq6 that was done 2 and a half years ago. Emil

Thank you! Even though I'm not even close to being "up there" where a lot of people on SGL are, I decided to try and put a bit more effort in my astrophotography and even though I can't afford more expensive things to make my life even easier, I'm just gonna do my best with what I have and if that means I need to shoot much longer to get the results that I'm after, so be it. I've gone passed the stage when I wanted to shoot 10 targets in one night. Now I only shoot 5 but that's because my veiw is very restricted 😂😂 Emil

Thanks Adam, I'm really glad it came out ok, it makes me wanna shoot more and more of them 😊 Emil

This year, because I love small targets and especially planetary nebulae, I decided to start shooting a few to see how they come out with my AT106 and Qhy183m. I'm quite oversampled at 0.72"/px when shooting at 690mm, with the qhy183m, but In order to get a nice looking crop I decided to drizzle x2 for the crop and reduce the wide view photo to its original size. The first finished target is M76, The Little Dumbell nebula. With a total of 35 hours and 40 minutes, it's my longest integration time that I’ve done on a single target. I have a few more of these small gems in the making but I really wanna do at least 30 hours on each one, so that might take a while because of all the good weather we've been getting in the UK. I shot it in HaOiiiRGB, stacked and combined in APP and processed in Pixinsight and photoshop. I really like it, I hope you do too. 😊 I'll add an astrobin link with all the details later when I upload it there. Emil

Wow, that is amazing! Insane integration time! Emil

Thank you! Unfortunately I don't have the 450D or any of the telescopes used to shoot that target but as far as I remember, I never kept the SD card in the camera. A friend told me that using the camera at ISO1600 would show a very good improvement but not having the camera anymore, I can't test it. The canon banding removal script in pixinsight combined with the background flattening tools in fitswork did a pretty good job. Emil

And here's the annotated version.

This is why I never throw away data that, at the time, I think it's good for nothing. I revisited my Deer Lick and Stephan's quintet to see how much better my processing skills are after one and a half years. Here's tonight's attempt And my previous attempt: It wasn't very easy to get to this result but I'm really glad I managed to do it properly this time. Here's how the pixinsight autostretch looks like. The 450d banding is absolutely terrible. Full resolution and other details on my astrobin account: https://www.astrobin.com/ncv0wn/0/ Emil

Hi. Any idea when the 1.25" Oiii 4.5nm will be back in stock? Emil

I went back and reprocessed the cluster and I'm even happier with this version.

Haha, I stacked more hours in less time but the amount of subs (457) is very large for my computer (quite old I might say) and the fact that it had to stack subs shot with 3 different cameras, including CCD, at different orientations, made the local normalization take much longer than usual. I do need a new computer because sometimes during stacking, I thought it was gonna take off and fly around the room 😂😂 Emil

The Ghost of Merope is in there too 😁

I decided to stack everything I have on the Pleiades from the day I started shooting it and I have a total of 22 hours and 35 minutes. 457 exposures ranging from 2min to 10min shot with, DSLR (600d), CCD (QHY10) and cooled CMOS (ASI294MC) through my TS65Q. It took APP 40 hours to stack them all. What do you think? Emil

That's a very good tip, thanks. Emil

I had another go at it to try and give it a more natural colour. I used the Ha as luminance, Ha + Sii for the Red and Oiii for the green and blue. what do you think? Emil
