I own the 72ED but use it with a DSLR currently. You need 55mm backspace between the back of the scope and the camera. The easiest way to achieve this is to buy the field flattener (noting you don't have one yet). You could try a 2 inch t-adapter? That would give you enough spacing, you'll just need the right adapter to then attached your 183. I don't know if such an adapter exists - sorry, I've only ever used a DSLR. Somebody more knowledgeable might know 🙂

Yes I've also tried it with a single battery. Also checked with just the non-Canon battery to see if that was causing the problem but it doesn't seem to be. As soon as I take the grip off and try either battery straight in the camera the problem goes away. Interesting thought. Do you think it's excess heat from the grip for some reason?

Yep, I find it very odd too! I took my darks at 4am, with everything still setup and the viewfinder covered. I've just done a test in a dark cupboard, with and without the battery grip, and unfortunately the grip is definitely causing the issue but I have no idea why

Thanks Dave, I think that's probably the answer but I was hoping to avoid it if possible. Yes the glow is in a dark frame too

Hi all, after a bit of advice... I've been using my 650D for 2 years in total and had it modified at the start of this year. I've had absolutely no issues with amp glow until this week, when I added a battery grip to allow more imaging time in one night. This is the only thing I've changed in the setup and can only assume it's the culprit. It's the genuine Canon battery grip but one of the batteries isn't. Anybody had this issue with battery grips before? I'll be very disappointed to revert back to just one battery. I'd considered a dummy battery with dew heater, but my controller is only 9 months old and I got the battery grip from CameraJungle second hand for £35, which seemed like a bargain. edit: I've added an image for info. This is with one curve stretch applied in Photoshop. The glow is in the bottom left, and my images from last night have the exact same issue. Thanks Nick

I want to frame a couple to put them on the wall at home and maybe gift a couple to family. Nothing too big, something like A4 size I think would do nicely

Hi everyone. I have a couple of images that I'd like to get printed. I don't have a good enough printer to do this at home so I'm looking for recommendations of online printing companies you may have used? Also, it seems 300DPI is the standard for prints, does that also apply to DSO prints? Thanks Nick

Ah brilliant thanks so much! I knew it would be either plane or satellite I just hadn’t had a trail look that strange before. You are correct. IC1318 Butterfly Nebula, the bright star at the top is Sadr 🙂

I’m used to having trails in my images but this one seems particularly odd with the short red and yellow lines in the middle! Anybody know what it is?

Today I received a bahtinov mask and the Optolong L-eNhance filter but sadly I can’t use them until next week as they’re a birthday present from the wife 😭

Great idea! “See” you all there 😃🔭

I sent mine to Juan at cheapastrophotography.com a few months ago. He turned it round within a week and if he damages your camera he’ll replace it like for like

Was going to buy the IDAS D2 as my local light pollution is LED lights. Is that the better choice or would this work equally well?

Welcome to SGL. Lots of very knowledgeable people on here who are always willing to help. Clear skies

Hey Adam, thanks for the tip. I did download that and use it on my image, worked really well on the cropped version but not so much on the full image. I need to try it out properly but it definitely made a big difference

First time I’ve ever shot these targets and I’m really pleased with the results. No filters used but I live in class 4 skies so it’s reasonably dark. Same image, I just cropped it to see if I could pull more detail out. Far from perfect but I’m really pleased with the result! 90x 2-minute subs with flats and bias Thanks for looking Nick

I’m hoping to be there. It’ll be my first astronomy show so I’m very excited!

I use the field flattener for the 72ED, which is actually the 80ED FF with an adapter. Got it here: https://www.firstlightoptics.com/pro-series/skywatcher-85x-reducerflattener-for-evostar-72ed-pro.html No I don’t use auto guiding. I can do 2 minute subs with this setup with no guiding. I have an HEQ5 for more serious stuff but I don’t actually have any auto guiding equipment at the moment!

Took this of the Orion Nebula a couple of nights ago. Only 60x 1 minute subs as it was a bit windy! Taken with my newly modified 650D and Sky-Watcher 72ED 🔭

Yes they were unguided, around 2 hours integration time for each image. My post processing is far from perfect but you get the idea 😊

Here’s a couple of examples with 2 minute exposures

Have you considered a DSLR with a flip out screen? It’s an absolute lifesaver unless you’re running APT with a laptop. You can get your camera modded from cheapastrophotography.com (I’ve just had mine done) after purchase. Or you can buy a modified camera from him directly. The 1300D is a fine camera and you’ll be able to get some great shots with it

I use an HEQ5 with 72ED. I generally shoot 2 minute exposures with no guiding but I could easily push that a bit more I think

Welcome Chris! Some fantastic images there, nice work!

My third imaging session with the Sky-Watcher 72ED did not disappoint! After FINALLY having a clear night for a few hours. Included below is the full image from last night and a cropped image which I could stretch more. Feedback welcome 57x 2-minute exposures 25 darks 30 flats - not sure if these are right. Are my flats causing the gradient across the wider image? 50 bias
