This is my 1st attempt on this target, It's not going to win any awards i know. 🙂
Overall i'm happy with the fact that i captured data and you can tell what the target is, although without doubt there is room for improvement, also my processing skills are somewhat lacking to say the least,
this image was taken with
Sky-Watcher evostar 80ed (blue tube version)
EQ6 Pro Mount
Modified Canon 600d + 12nm HA filter (cheap version) 😀
All controlled with ASIAir Pro
24 x 5 minutes exposures ( 36 were taken but 5 not used )
Darks, flats, bias frames were also used,
Images were only stacked in DSS then saved as Tiff and transferred to Photoshop were only levels and curves adjusted.
Any criticism on the image is welcome, and thanks for looking.
IC1805 Heart Nebula
I have been imaging the California nebula and found that there was a large gradient in the final image. I have now taken some flat frames for the setup and found that the gradient was in all of the photos and took up about 1/3 of the sensor space.
I have attached an image of a flat frame to show the issue.
I am currently using a skywatcher esprit 100ed with my ASI 294 MC PRO. Between the two of them are, field flattened, ZWO OAG, 2 spacers and ontology l-enhance filter. I have checked down the objective and can see no issues with the alignment up to the filter. All threads are screwed in correctly with a snug fit, and there are no massive pieces of debris covering the objective.
need help ASAP please.
I'm considering the 250PDS. The main use is visual, and the second is EAA (I currently use a zwo183mm).
What I'm hesitant about is the primary focus. since It's mostly for visual, I'm wondering on how much back focus it has compared to the standard Skywatcher 10" dobsonians? with the standard dobsonias with the same optics and focuser you already need an extension tube for most eyepieces...
Also, there's probably a "bigger" obstruction (bigger shadow on primary)?
I have a SkyWatcher AZ-EQ5 mount. It’s all working fine, except I have an issue with alignment. This applies whether I’m in EQ or Alt-Az mode.
I set it up using one or two star align without problems.
However if I use the handset to GoTo another object, I usually need to do fine tuning adjustments to centre on the new object. But the mount disregards these adjustments, so if I use the GoTo system to centre on a nearby object, or revisit the original object a second time, it’s still off by the same amount.
How do I tell the mount that I have centred on the new object and that it should now be aligned with that object ?
My iOptron MiniTower has a feature that does exactly this – once set up correctly and aligned, for each new object I go to there is an “ALIGN” option, and if I use this it now knows the correct position. Can I do this with SkyWatcher and Synscan ?
