  1. Hi, I'd like to know if its possible to combine data from two different scopes on different mounts into the same image. Ideally I would like to supplement images taken with osc dslr through a redcat with Ha data taken with a completely different scope, mount and camera. Im trying to get my head round what the work flow for it would look like. I think I can get framing where I would want it to be, but at what point would I add in the stacked Ha data? Do I have to resize images, if so how? Because the fov is different the size of everything is different stars from one setup would be bigger than the other set up. My biggest concern is combining the two images on top of each other correctly. Is it something I do at the DSS phase or is it something I do in photoshop? My worry with doing it just in photoshop is aligning the two images precisely it seems like it would fiddly to do it by eye. I saw that there might be a potential Pixinsight solution although I'm not sure, I try to avoid PI if possible because it seems so much harder than photoshop. Thanks,
  2. I bought a bigger losmandy bar. It's about 5 times bigger than the one that I originally had. Its fixed the problem perfectly, I'm looking forward to a clear night to see what guiding improvements have been made. Thanks,
  3. Don't worry I just got it! Took me too long to process.
  4. Ill look into the longer dovetail. That seems to make perfect sense. Im not sure how that front weight works and where it gets attached to? Could you share a picture of it in action?
  5. Hi, After a recent purchase of a camera and filter wheel my scope, esprit 100, has become very unbalanced in Dec on my mount- eq6 pro. I dont think I can buy any more weights and to be fair in RA my scope is balanced perfectly fine. The issue is that due to the scope design I cant push the OTA anymore forward. Im concerned that this will cause guiding issues. Is there an easy way to rectify this? Picture of the scope and mount.
  6. Just a quick follow up question re using an LED panel. I have one, but you can clearly see that the light distribution across the panel is not even. Is that a problem when taking flats with this method, or not really?
  7. I did a search and found this, you can use a LP filter with LRGB filters.
  8. Thanks for the response. Ah that's good to know, I didn't know that. I'll probably tend towards the LP filter then. Another question I had was do you know if people ever put a multiple filters in the same image train, so an LP filter and say a HA filter or and LP filter and any of the LRGB filters? Actually a HA or O filter probably blocks out LP anyway? So I guess an LP filter with LRGB? Best
  9. Hi, It would be good to get your advice on which filter I should consider investing in. I would ideally like to only buy one filter, as the cost of having two or three filters quickly adds. A bit of background, I would like to use the filter either directly onto a Canon EOS 5d Mk3 or with a WO Redcat 51. Currently I am undecided on which filter to add in. I tend to be imaging in and around Bortle 4-6 skies, so naturally an LP filter like this Canon filter or this might seem like a good fit. The full frame canon filter does cost more for the same thing, the advantage of it is that it slots right on to the camera sensor reducing any potential vignetting problems, but if I change the camera to a dedicated astro camera it probably becomes redundant, so I would rule it out and go with the 2" filter that would slot in with the Redcat. That being said, the cool thing with an LP filter for the Canon is that it could help with getting some really nice Milkyway shots, so its another thing to consider. However, considering that most of the targets I would like to be capturing are likely going to be big nebula with the redcat should I be more in the market for one of these, a duo narrowband filter of some description. As I understand it the Narrowband does block LP as well, so it could be a two birds one stone situation. Ideally, I'd like to settle with just one filter, especially because I have recently gone mono with my other set up and the filter costs what with the wheel and Halpha filters and all that are really starting to make a considerable dent in my wallet. Best,
  10. Can you? I dont know, if you can it would be good just for the polar alignment with sharp cap like you mentioned. I hadn't even thought a about having to add the redcat on after PA. You're right adding it would definitely knock it and mess with the polar alignment. Thanks,
  11. Hi Guys, I have recently picked up a star adventurer the mount and I was wondering whether it is worthwhile using the autoguide functionality with it. I plan to use it with both a DSLR for widefield, and a WO Redcat. I hope it will be portable and easy to pick up and take with me on my travels. I am used to guiding with my eq6 mount, but when I do the mount is guiding in both RA and DEC, but with the Star adventurer it only guides in RA. I guess a lot will come down to exposure time, and certainly for the DSLR and widefield shots RA guiding should be more than adequate, perhaps even overkill, but with the Redcat will RA guiding do anything at all. By the way when I say guiding I mean the corrections in RA as opposed to the mount tracking. If anyone has a similar set up, especially with a redcat or similar focal length OTA I'd be really interested to hear your experiences. My biggest concern with just guiding it anyway is that I think I would have to have two laptops with PHD2 on each if ever I was guiding both the star adventurer mount and the EQ6 mount at the same time. Whereas, if I don't guide the star adventurer I could get away with just having one laptop to guide and capture with EQ6 mount and have the star adventurer/DSLR/redcat combo used with just a shutter remote, which does save me hassle in a way. Best,
  12. Hi, I would like to ask what does 2x2 binning do for you with this picture? I am aware of what binning is but have never been sure on how to apply it. It looks like you have applied it to great effect because it is a stunning picture, but I am just not sure how and why it helped. Best,
  13. Thanks for the reply. What is stopping down? I did some research on aperture, something that I have never had to think about properly with a dedicated astro camera attached to a telescope. I had set my lens on APT to max aperture, so the lowest number possible and perhaps I could experiment with pushing that number up a little bit to see what happens. Re the lens I have come across a company online that does lens repairs. I am going to give them a go. It won't be cheap but still better than returning in its current state. Best,
  14. Thanks for the message. I will be in Andalucia, staying near a town called Motril. I will have a car, and wouldn't mind a drive up to some peaks. Let me know where you recommend. Insect wise I can imagine it to be a problem, my plan was to keep the scope set up outside, but given what you said I may bring a dust sheet as well to keep it protected during the day! Best,
