That's my home town! Where about were these taken?

Hmmm, I hadn't noticed that! I have no idea why the image is 10,000 x 10,000, it certainly wasn't on purpose!! The FOV is slightly smaller because after restacking I had some artefacts which I cropped out. I'm still not happy with it to be honest, so I will have another go tonight. Thanks for your comments

A little, but you've brought good nebulosity into the faint areas. It's at the point just before where you are that you need to decide if you'll push it that bit further Don't worry, for my own, I did the same
Look out for the background (not dust/nebulosity), it's got some red/magenta creeping in. Here's a side by side with most of it removed. It's not perfect, just an quick example.
Thanks! It's the background I tend to struggle with in processing, I will have another go and look out for this.

1st time out imaging in months because of work, kids and mainly clouds! This is my 2nd attempt at M45, taken over 2 nights, to give about 8 hours of data. I think I've overdone it a bit is processing, and made the image a bit noisy. But I'm out of practice and it's the best I've managed this far. Let me know what you think. Processing done in Siril and Photoshop.
Let me know what you think, CC welcome as always
Thanks

Wow, that looks amazing. Love it. The histogram looks clipped but that maybe just the image thats been uploaded.
Hmm, you might me right. I'm only just starting with Pixinsight, so I might have pressed something along the way that has clipped the histogram🙈

I used the Evostar 80ED and Zwo 533mc👍 Those subs look good, I look forward to see the final result

First time shooting this target, captured about 4 hours of data last week using the l-extreme filter and the equipment in my signature. Calibrated with darks, flats, dark flats and bias frames.
Really struggled processing this, but this is my best effort so far. Used DSS to stack the data, and mostly Pixinsight for my post processing. My first effort doing a false Hubble Palette, so any CC would be welcome.
Thanks

Not much has happened with the actual build this week but my wife has completed a blind for the inside of the windows and the support posts have grown leaves!
I did get a couple of evenings with clear skies this week and put the HEQ5 and Evostar 100ED DS Pro onto the pier for the first time. This was mainly to make sure the roof cleared the scope and it does, just!
I did have to rotate the focuser so the EAF cleared roof and didn't hit the pier when imaging.
The metal plates I got for the discs are now in place and work well. The one which holds the mount securing bolt isn't fixed to the underside of the disc, so I can remove it if needs be. The mount is solid on there now and I'm really pleased with the pier.
I still need to make something permanent for the laptop, but I've got a fold-up table in there at the moment and a small seat, which work fine as a temporary measure. Power is supplied using an extension lead run from the house and the 12v 10amp PSU sits under the mount, again, this will be fitted more permanently later.
Tuesday night was looking good for a clear night so that's when I setup the mount & scope, as it turned out, it wasn't that successful because it clouded over quite quickly and I only managed to get the mount polar aligned with SharpCap and saved the Park position for the mount in EQMod.
Last night (Thursday) is was looking good, so I got out there just after 9pm and connected the laptop & power. I then used APT's new Polar Alignment tool to find turn the AP using the main camera, after getting the focus right.
I then setup on NGC6914 in Cygnus as the first light target, also as a test for the L-eNhance filter I acquired from a fellow SGL member recently. I managed 38x 240s images before the cloud rolled in but only used 22 of them due to high cloud on some of them. This also included an meridian flip, which I let APT do on it's own and it went without any issues, although I was poised over the STOP button!
So here's my first light from the Obsy and for this season, 1h 28m of NGC6914 stacked & processed in PI.
Looks like the l-enhance is working nicely! Great obsy build, I'm not at all jealous😬

First time out in over two months due to the weather and work commitments. Also my first time shooting this target, and a first outing for some new gear. A newly belt modded HEQ5, L-extreme filter, EAF and ASIair pro.
I'm very pleased with all this new gear. ASIair is just a dream to use compared to RPi and Stellarmate/Ekos. The auto focuser worked without any problem, and the HEQ5 was guiding at half it's usual RMS, keeping steady at 0.4-0.6 all night.
This is about 8 hours of 3 minute subs. Calibrated with darks, flats and flat darks, and shot using my Evostar 80ED and Zwo ASI 533mc. Processing was done in Siril and PS.CC welcome as always

This was waiting for me when I returned from my holiday this afternoon. Thanks @nephilim. Clear outside is forecasting a couple of clear nights aswell😁

L-extreme delivered this morning, thanks @Budgie1 for the quick delivery! Some clear skies would be nice now, it's been almost 2 months since I've been out imaging😭

I am by no means an expert, but I don't think you would need both the l-pro/l-extreme and the uv/ir cut filter at the same time, it would be one or other. I have a similar setup, and use the l-enhance for nebula, and uv/ir filter for broadband, but never both together.

I have a zwo 533 with the 80ed. I was slightly concerned with the square sensor originally, but can honestly say I've never thought about about it since. Calibration wise, it's so easy, but I only have the my 600d to compare

That's a very interesting read @malc-c. Thank you for putting in the hours to develop the mod so that even numpties like me can install it!😀
I'm off on holiday for a week now, so I won't be able to test it out properly for a while.
-
Thanks @malc-c. I managed to complete the mod without removing the connectors in the end👍
As you say, there was plenty of slack in the cables. I've read various instructions and watched youtube videos of this mod, and have never seen anyone do it without completely removing the motors.
Otherwise, I found it a quite straight forward mod, and I'm not particularly skilled with these things.

You may be able to do the swap without disconnecting but it will be a much more difficult job. Also, the DEC cable is normally wrapped around other cables inside the casing to stop it from chafing on the central tube, this restricts how far out the motor will come and you can't free the wires with the connector fitted.
Have a look at 4:25 in this video and he explains how to free the connectors they're not that willing:
Thanks for the reply. Unfortunately, I've tried this technique, but it won't budge. It felt that if I applied any more force, it would break the connector off the motherboard. I've emailed flo, so I'll see what they have to say before I go any further. At the minute, I'm tempted to attempt it without disconnecting them, and see how I get on.

I've just purchased the belt mod kit, and I'm having an absolute nightmare trying to remove the connectors from the main board. Is it possible to complete this mod without disconnecting these?
Also, it mentions on the @FLO website to keep the connector connected, and just free the cables(note 2 below).
Thanks in advance

Hi @Anthonyexmouth. I fitted mine a couple of weeks ago. I used the holes for the counterscrew and focus stopping screw to fit mine. I haven't had a clear night to test it yet, but have tried it in the daytime and it seems o work fine.
However, I did need to adjust the tension of the focuser after removing the 2 screws, as the focuser was slipping, but it seems rock solid now. I followed the guide in the link above to do to this.
Good luck

Success! Did exactly as @Budgie1 suggested, and secured the coupler slightly outside the casing. This made actually mad fitting the bracket easier as well. Will try and connect to stellarmate next👍

Clear nights compared to previous years.

I have imaged about 3 times this year in North Wales. Like many I don't set up unless the forecast in good enough to confidently leave my set up out all night. Also, work and young children limit available nights. It's frustrating, but I feel it's still worth it for the excitement of a crystal clear night when everything comes together. However, I feel I can't justify spending much on astro gear these days
