Another thing to check would be the guiding scope setup in PHD. I had issues when I had not put in the correct focal length details here. Good luck.

Hi. Is the etx90 still for sale? Thank you.

Not sure, but Altair says: "Works particularly well for refractors telescopes of F5.5-F8 focal ratios, however also known to work with RC telescopes."

I have the Altair Astro 0.8x reducer/flattener - https://www.altairastro.com/lightwave-08x-reducer-290-p.asp

Great picture! Just a word of caution with OAG and refractor. I used (with some success) an OAG with a 72mm refractor. I say some succes as guiding was lost from time to time through loss of clarity in the star. My guiding graph was "OK" but was a bit saw-tooth like. I then moved to a 32mm mini-guider and my guiding is now near perfect everytime - guide graph is almost level with minimal nudges. This was the only change and my images are much sharper as a result. The final image is of course the real test! Best regards Matthew

It will certainly improve your images. I use a 0.8x but not this one. It will reduce your effective focal length and therefore the f-number, allowing you to take deeper images (more light gathered for the same exposure time when compared without the reducer). Regards Matthew

Skywatcher 72ED. What extras will I need to attach DSLR
rockinrome replied to Arlen's topic in Getting Started With Imaging
Agree with Chefgage - flattener/reducer is a must. You will also need the T-ring adapter to attach the camera onto the back on the reduder (I have the altair and this is possible - don't know about the OVL). With this you will need to handle the back focus of the reducer to the camera - so from the lens of the reducer to the focal plane of the camera (should be in the spec. of the reducer). For my reducer this is 55mm. I have a Canon 600D - from lens flange to focal plane this is 45mm, so I make up the 10mm difference (luckily) with the T-ring that screws into the reducer. Easy r -
