The way I resolved this issue on my Canon 550d (almost) is by removing the SD card out of the camera. Someone on here Carol if I remember correctly suggested I try. Since then I don’t keep a SD card in. I believe it’s a electronic signal being picked up in the frame. Give it a try Gerry

Hi Alacant Whats the benefit of the guide camera being binned? Thanks Gerry

I think the issue is more the length of your exposures. 20 seconds is not enough to get the detail you need. The background in the first picture is too bright. In photoshop try to get the black levels to around 30 that will help to see more detail in the galaxy. Kind regards Gerry

I'm still on dslr and if price is no option God willing I would probably go mono there is still a temptation there to go one shot though. So even if you don't have a permanent setup you would say it's still faster? So using Ha on red and Oiii on blue and normal green for improving star colour and size? Learning a lot Thanks

Love it when people go against the flow I have to say it's quite convincing just a quick question if I may. With the first picture if you needed to improve on it would you increase time on rgb or spend more time on luminance or h Alpha? Is there a sound ratio to colour and luminance that you follow? Thanks Gerry

I'm pretty sure it won't work with a Newtonian Unfortunately you will need one if you want to do imaging.

I don’t think that you can use a SCT coma corrector on a Newtonian I doubt they would be compatible. Someone will give you the technical answer I’m sure. Kind regards Gerry

Wow fascinating. Love to see what kind of results you get. Anyway for another thread.

A spectrograph. It's a area I know nothing about. Could I ask what you use it for? Related to spectral analysis of stars etc? Regards Gerry

So that's where all the confusion is. Types of prism looks like one is reflective another transparent. As you say we live and learn. Wonder what works best in practice. Good to know actually because later if like for me I decide to get a cmos then i might need a different oag. All the best Gerry

Ah yes it is quite different. Looking at the picture looks like a clear prism? No matter as long as it works. With mine which I also bought from there but made for dslr you cannot adjust the mirror like yours but it works fine for me let us know when all is working.

Actually looking a little closer probably both are correct it's just the angle of the prism that threw me. Regardless of the pictures. Thanks google! The idea is light comes down the telescope to both the camera and the guide camera in the same direction one small part gets refectled up by the prism towards the guide camera. That's the principle which is clearer than pictures obviously in this example. Apologies for any confusion. Let us know when it's all working otherwise one of us will pop over to fix the mess I've created

Actually the picture above is incorrect the angle of the prism will be going towards the focuser not the camera Kind regards Gerry

Looks awesone but how is it balanced mine has something similar with a USB hub on the scope. Powered like yours. What do you put the better guiding down to? Losmandy? Gerry

Woooo guys and girls. Your putting me right off the star adventurer! I think a pier project might be more suitable instead. Let's hope the wife agrees!

No I didn't want to go to the maximum weight but I just wondered how these tripods would cope with a small scope and guiding. If they are both up to the job great. Gerry

Thanks to everyone. Can I ask what are the differences in weight capacity for Neewer and FLOs tripod. I'm certainly going to be putting a small scope on mine and probably auto guiding etc. Do they both work ok for that? Cheers

Hello all Can someone tell me what I need for star adventurer apart from the mount. A long shopping list. I would like to do this setup but not sure what I need. Also would like to add guiding. Can people explain what tripods etc. I can order everything from FLO if they have it Gerry

I have already modified the same camera. Huge difference! Wouldn't go back. Couple of comparisons below but the also guiding was added as I didn't have that before

Great shot. Here is mine on my T2 unmodified last year. Mine has even worse HA than yours!

So just so I understand. In PHD2 you set up guiding on a star near the equator leave that going for a hour and a half then create a log file. Then load that into Eqmod pec prep? Sorry never done this but would like to try. So PECPREP is part of Eqmod right? I'll have to google this maybe @chrisshillito has already done this as I know he designed it. Gerry

In my limited experience I think it does improve things but it might be easier to get a pole master and get the improvements that way? Rowan mod isn't easy by the look of it. That sounds like a plan. Great. I'll certainly take the principle that PEC needs to be created raw. Unfortunately at the moment I don't have a permanent setup but I could in theory set up early let it record what the mount is doing and apply the curve once I start guiding?

I've always been unsure about PEC. Do I need to record it during guiding and then apply it or create a PEC file before in guiding and then apply it when I'm actually guiding. A little tweak extra towards better guiding.

Your way ahead of me I'm still learning dslr so luminance etc is not something I have tried. I imagine that at the resolution of those pictures it's going to be tough although it depends on the mount I guess. Great pictures. Here is the link http://www.goldastro.com/ Gerry

I'm not sure if you have encouraged me to stay away from RCs still sounds quite complicated. I guess it isn't. I think I have enough problems with my F5 newtonian although its getting better. Have you heard of the gold star collimator? Works with its own software and looks great. I think that's what it's called if I find the link I'll let you have a look. You probably already know it. I was tempted to get one for my scope. Comes with a special type of Bahtinov mask depending on what type of telescope you have and the software with it. Do you post any pictures anywhere from your RC? I'd be interested to see. Gerry
