They are not good at all, at answering emails or the phone, …and I mean “not good”….😉

Try Facebook messenger, that seems to work….

Thanks Stuart. Unfortunately I don't use Facebook (which seems to screw me over a lot) so I guess I'll just have to import what I want from Germany!

I've tried to email a couple of times in the last 2 weeks, tried to call a few times - no response to email and no one to answer the phone.

I have a stock enquiry (website says to email to check stock). I don't want to pay them if they're out of stock and won't be possible to get a refund!

Supplier reviews threads are all locked, so posted in the only place I could think would accomodate a thread such as this.

Cheers

Dude that is absolutely awesome, nice job.

That is a ton of detail from the city with no filter, Lee. It's definitely not over processed like lots of M31s I see. Nice job mate

This is going to be so rad when you get the mosaic done. Nice work man!

Lovely work Peter, one of my favourite targets

Cheers mate! I only have access to Northern skies from my garden so I'm on the hunt for good ones that 500 to 800mm focal lengths will excel at if you have any tips - my horizon in Stellarium attached.

This is my 2nd attempt at photography, and this was way harder to process than the last. Starting to feel I understand what over-processing is!

This is only one hour of data so I need to start actually getting some reasonable time on targets and hopefully that will help with the noise.

The 2600MC is quite something. Still trying to shoot things with the light-polliution busing L-Extreme filter.

I need to work out what's going on with tracking or field flatness or something. 

Cheers!

Yeah it should apply. I think you'll end up making HA = Red and OII = Green and then sythesise a blue channel from 60% red and 40% green after some curves and level adjustments

Take a look at this video from Luke who explains a lovely way to process HOO. This is for OSC data.

Some fool,- definitely not me - was trying to drink a glass of Sainbury's Cava whilst adjusting the scope on the mount.

The mount was pointed at the NCP, and the dovetail slipped through the mount grips and to the floor. 'Definitely not me' managed to 'save' it from concrete with the interjection of a well placed foot and not a small amount of Cava was lost.

After I got it back on I noticed that the 3" Crayford Focuser was slipping out and the EAF could move it out, but not back in/up. I Googled it and properly tighted a hex screw and that issue appears to be fixed.

However, when I took the flats from last time I was out vs this time - I get something different - which worries me. The scope seems to be totally shifted over on the flats.

I've uploaded a single light frame from last night also.

Any ideas?

EDIT

So I have found this morning that loosening the hex bolt under the focuser moves the flat circle back to centre. However, this also means the focus moves loosely and falls back. I can find no way to loosen the hex screw and keep it tight - there appears to be no opposing tension screw on the top.

If you are using the ASI AIR, try these 2 tricks for framing.

• Take a preview image and then do a long press somewhere on the the picture with your finger. ASIAIr will let you centre to where you long pressed. With practice you can centre where you like. MUCH easier than messing with cursor controls.
• Once you are framed and have a picture, you can view it anytime in the image management section and there is an option to goto that precise location by plate solving. VERY handy if you re-visit a target you have previously framed.

Hope this helps

 

Awesome thank you for those they are going to be helpful.

My son has decided that we should try for the Bubble Nebula tonight so we'll give it a go

If you're using NINA for PA  then why not use it to frame and plate solve 

As for the guidescope,which one are you trying to use? It's either a focus or exposure issue..

Nice image, your next one will be awesome 

Hey mate

I'm hoping to use the ASIAIR I have so I can monitor it from the house. If I can't get it all to work then I can fall back to the laptop for sure. I need to work out a method of getting things framed. 

Is it possible to plate solve an existing image off of the internet and get the scope to plate solve to that to help with framing? So you kind of get the scope to where it needs to be and then manually slew to the exact place?

I'll dig around, I know I saw somthing on Telescopius.

The halos are caused by the filter. I've seen lots of images produced by the Lextreme and they all seem to have halos on bright stars. Small though, they don't take away from the image.

Ah right ok, thanks for this. Lee said below he photoshops them out.

Here's my Elephant's Trunk using the same camera and filter, Bortle 8, and also following @Luke Newbould's excellent tutorial. Regarding halos around stars, I fix those as part of my standard workflow: after making a starless version using Starnet++, I then clean up any aberrations -- including the leftover halos -- using the clone tool in Photoshop.

Hey Lee - I found your website the other day. You've clearly put a lot of work in to it and it is becoming a great resource. Cheers for doing what you do. Helpin' us nubs. You capture here tells me that 90mins of data aint gonna cut it and I need to get more blue nebulosity data.

Nice one mate. That target was also my first ever image a couple of months back using exactly the same video.

Dude that Samyang is just nuts. Nice one.

If that’s your first image! I can’t wait to see what you are capable of in the months ahead! 
very nice processing, framing probably needs a bit of work but overall bloody brilliant! 

Thanks for sharing

Wow thanks mate, honestly it's all don to that PI tutorial I linked. And the fact the Optolong L-Extreme / 2600MC are just so outrageously good. 

Lots to learn but I'm excited to get more data. That was only 98 mins

Hi

This is my first image of anything so I'm sure there's a million errors which I couldn't even begin to appreciate. I couldn't get my guidescope to focus at all so this is unguided. Good polar alignment thanks to NINA's Three Point Alignment might have saved the session somewhat.

This is 49 x 120s subs through the Optolong L-Extreme Filter taken last night after I lobbed the guide scope in a bush. 11 rejected frames from me poking said guidescope while imaging (lesson learned).

Altair Astro 115mm APO from 2013

2600MC

Pixinsight to put it together and stuff. Followed Lukomatico's noob guide and he's the man (https://www.youtube.com/watch?v=QV6ObLVRvNk)

Some weird halos on the stars, no idea what that's about.

Framing - no idea - just told the scope to aim at it and go. Probably need to work on that strat. 

Cheers

Cheers mate, it's more specifically trying to map out the trees and buildings around my garden which cause me the most grief. I know there are good windows for many objects passing through the gaps. I need to snipe them.

Found this on a Cloudy Nights post. I have a very heavily obstructed horizon - it would be great to be able to map out what I can see and when I'd be able to see it.

Cheers
