I found one screenshot showing the raw stack. For me it's not acceptable and I won't repeat the manual halos removal anymore.

Hi, 

I love your project. Please can you share the stl files? I was about to try to figure this out myself.

I use Myfocuserpro2 project for DIY focusser. And will use Nina autofocus. But I need a solution for scope rings, focusser gear etc and yours look great.

How's it been performing?

I'm sorry for the late reply, after the defeat mentioned above i temporarily abandoned the project, but now it's coming back.

Are you still interested in the files?

Hi,

Thanks for your reply. I didn't do too much, only the California Nebula: https://www.astrobin.com/hnlo7s/B/ . It looks quite good now, but I had a huge problem with significant red halos around all stars, which I removed manually. I used a Baader Canon ring with an extra compartment for 2" filters where my L-eXtreme was placed. Some people said that the halos could be caused by the filter. Now I declared a purchase of the full frame Optolong L-Pro filter here, on the SGL, so I'm going to give it another chance. I have only several targets for this setup: M31, M42 with the Horse Head and the Flame, maybe the America with Pelican, but it's again another filter needed.

Not sure how your getting on, but an important learning for me was that it performed much better at f5.6 than it did wide open. Hope you're having fun with it.

My question is how does the F/5.6 appear better than the F/4.5?

On 9/6/23, before the 1st night of the Iris Nebula (and before the thunderstorm...).
New components added: a trustworthy Losmandy-style dovetail by Altair Astro as a base and a WO Vixen-style one with clamps just for accessories. The Vixen-style clamps for ASIair offered by the FLO are so strong that my Evoguide attached to another imaging setup (APO) doesn't even twitch. 🙂

And one more for now.

Check that too when you contact Bresser. The Bresser Messier range have 10 year warranties but you might need to register with them.

It's a budget telescope, I don't think that they will fix the problem. 

BTW, I thought about a custom carbon tube, but going towards i.e. GSO/iOptron/StellaLyra 8" RC OTA seems cheaper. It's smaller, shorter, lighter and in the meantime it has a longer focal length. Of course, it's about the astrophotography. 

Hi, 

Thankfully, it works that I got the post as well... 

I place a link to my post on the bottom. Yes, I'm imaging. I understood an origin of the problem after analysis plenty of final pictures after stacking. There was a kind of uneven shadow on the bottom of pictures caused by lift up mirror of the Canon DSLR (180* rotated image) that was unable to eliminate by series of flat frames taken, when the OTA was in a vertical position. It was caused by the gravity: the camera was changing it's position within a night (EQ mount). BTW, nobody was able to explain this effect looking at the pics. 

After my modification (unfortunately involving a lot of drilling) I never experienced this effect. Now I use a heavy cooled astro-camera, OAG with its camera, filter drawer and EAF auto-focuser. I don't think that your EP is heavier than my items together. Now my subframes taken over a night move across the picture only because of the guiding or GoTo imperfections. 

My conclusion is that the steel wall is not stiff enough and in my opinion @Ricochet is right in their suspects that their 8" OTA is stiffer because of its smaller diameter.

And no wind 🙏

Maybe I don't have the best views and unlimited horizon around, but I don't have the too strong wind as well.  Also, I have two extra counterweights from EQ5!

Yeah, this is the new setup based on old stuff. Not bad, if we take into account that it's OAG @ 1284mm fl and over 18kg OTA with accessories.

I really like the CGX together with ASIair Plus.

I will title this image seconds from disaster...

Very light up here the now and couldn't get sufficient stars to polar align until about 23:30, however the mount had a dodgy zero position lodged in it from the last time I used it so when I asked it to slew to Vega, it slewed to try and look at the core of the earth, fortunately I was sat beside the mount before anything collided.  Managed to figure out the issue, but by then the clouds had arrived.

Still, not a complete waste.  Setup was very quick as I've adopted @Elp technique of having everything ready to go, just move the mount, pop the imaging rig on and connect a couple cables.  defo a winner that.

The imaging rig is a good thing, I also have one based on my Altair 102EDT and Evoguide. But another setup based on already owned gear is just tested...

Hi,

It's a 4th night of the M101 (nearly in a row) and my first approaching the multiple-nights imaging.  

Hi, 

Everyone captures the AR3310 sunspot and its neighbours, so I do it as well. 

SW EQ5, Starwave 102ED F/11, (Barlow RevelationAstro 2" x2 ED), Hercules Herschel wedge 1.25", Baader Yellow, Baader IR/UV Cut, ASI 678MC.

Videos are still processed.

Hi,

I also hope to take a few pics of the M101 with its supernova. 

Tonight it's a test if a new child in the family: new ZWO OAG with a helical focuser, new ZWO filter drawer and already owned ASI 120MM mini and IDAS LPS-P2. Of course, ASI 2600MC-Pro is there as well. 

Recently discovered excellent cooperation of my OnStep controller (based on the FYSETC S6 v.2.1 board) with the ASIair Plus constantly impresses me - it's 1280mm focal length put on top of the home-made mount. 😳 Or is the mount so good? 🤔

P.S.. The Evoguide and ASI 224MC is there just in case of poor guiding by the OAG, warm and ready.

Hi,

Now I'm ready to present much better picture of the M51, which was my main goal till now.

The Whirlpool Galaxy (M51), 15-16/5/2023

Bresser Messier 10" F/5, Baader MPCC III, IDAS LPS-P2, ASI 2600MC-Pro @ OpusMagnum ATM EQ fork mount, ASIair Plus

This is a higher level of my primary setup: the 90kg ATM EQ fork mount with 17kg 10" F/5 Newtonian with accessories.

I wrote it's a higher level, because this setup never fully satisfied me till now. I used the Astroberry with its Ekos and PHD2. Guiding offered by the PHD2 very rarely was below 1" total RMS, usually it was nearly 2". Recently I bought the ASIair Plus and after obtaining decent guiding with Celestron CGX (around 0.8") I decided to give my ATM fork mount another chance. The result is outstanding, if we take into account that it's a fully home-made mount built from scratch: nearly all the session the total RMS was below 0.8", very often it was around 0.65" and sometimes reached really low value like 0.56". I think that the harmonic gearing used for the RA axis just showed its class. The question is why does the PHD2 run on the same Raspberry Pi 4 (my Astroberry has 8GB RAM) cannot do the same as the ASIair Plus?

Hi, 

Two hours before the run: coming back to origins and another level of the setup? 

After some significant amends described in the following post... 

... recently I found that the ASIair Plus supports the OnStep, so I cannot resist and must try it all together. 

ATM EQ fork mount, Bresser Messier 10" F/5 Newtonian, ZWO EAF, ASI 2600MC-Pro, Baader MPCC III, SW Evoguide 50ED, ASI 224MC, a home-made dew heaters controller, ASIair Plus  and... my smartphone instead of laptop with VNC. 

I love the external antenna of the ASIair Plus for it's awesome WiFi range! 😳 It's much better than the simple Raspberry Pi (Astroberry). 

Hi, 

Cooling down before hunting the M51. Hopefully tonight it will be first light for my new ASIAir Plus with the CGX. I'm very curious of their cooperation in terms of PA and guiding. It will be also test of how flat is my field after making the light path more rigid. Busy night, busy me...

Another approaching the Markarian's Chain (learning of the ASI 2600MC-Pro and the CGX mount).

Hi,

Right after the rain, hoping for clear skies: preparing for the Markarian's Chain.

On Thursday last week I bought a Celestron CGX mount and an ASI 2600MC-Pro camera from our fellow  @Hogarth. I've already made one picture ( https://www.astrobin.com/fqnvf5/B/ ), so it's not the first light in my garden. I love my ATM EQ fork mount, but my children grow and I can expect some nights elsewhere more or less soon. Unfortunately, my fork mount isn't portable with its 90kg. So, I have the CGX and want to learn it. The camera as well. 

I like compact structures, so everything is piggyback. Only two cables go down from the setup: power cable and USB one to the NexStar+ controller. My old friend Raspberry Pi with Astroberry system got a new housing with power distribution. I didn't need any USB hub, as the camera has 2-ports hub for guider and EAF. The efficient Xbox power supply provides 12V 16.5A power for all devices.

They're fantastic.  It makes it so much more comfortable.  Not thrilled by the strap arrangement, but it works.

I'd say that an observing chair is so good that I wish I bought one before I went off the deepend with eyepieces.

It's one of the "must have", I realised it playing with my F/11. When I observe something near the horizon, I seat on the top level (Baader prism and binoviewer) , when it's near the Zenit, I seat on the bottom level or on the 2nd one. All the time it's very comfy, even it it's a cheap (?) one.

I drove out to a spot to observe venus this evening. The clouds roll over and I had a Hamlet moment thinking to get back in the car and go home. In the end I set up anyway and had a look through thin cloud.

My friends said that sometimes thin clouds or light fog make the air more stable and details are unexpectedly great. I never experienced it as I have planetary setup from last summer. This year I'm going to spend a liitle bit more time with my Planet Killer, possibly while imaging.
