It's (n)ice to be here, in this space (...) and here's the first image I am actually posting here.
It's one shot from the Negev Desert in Israel (270 km from where I live) 2 weeks ago. It's my longest exposure to date, and the first full session with the Officina Stellare Veloce RH 200.
Great image Harel! There is a lot of variety here - blue reflection nebulae, dark nebulae, red emission nebulae and nice star colours! I don't think I've seen this one before.
This RH scope is an intriguing instrument. It seems to work well with the 8300 chip.
A couple of reflection green and red halos around bright yellow stars. What do you think caused that? I see you are using Astrodon Gen 11 filters. Were these reflection halos only with the green and red subs? I am not criticising here, merely interested as I am evaluating the performance of this scope as a potential scope for my own use and reflection halos is one of those performance criterions.

Thanks David,
Yes, this is what truly lured me to this area... I was stunned by the richness of it all... There's hardly any form seen in nebulae that doesn't show in this area!
Thanks! I am happy you liked it!
It's actually the first time ever I invest 4:20 hours in shooting color. It's been recommended to me for a long time now, by my friend Tal Faibish, but I somehow managed to silently ignore the self-evident. I am so grateful to have listned, as it really paid off big time :-)
Cheers,
Harel
I'm loving these images that are starting to appear from the RH scopes.
What difficulties do you find imaging at f3?
Thanks! The only difficulty you will seriously encounter in a short-focal-ratio scope such as the Veloce or the Powernewt, is the fact that the Critical Focus Zone is very small. It's actually +/- 10 micron...
That means, that any small tilt in the imaging plane, will translate into part of the image not being in focus, while the other part is. The part not in focus will reveal all sorts of abberations, which are difficult to handle. Hence you will find yourself investing some effort at the beginning of each imaging session, to make sure that you eliminate all tilt from the system.
Accordingly, I have made a carrying case for the Veloce, which houses the camera together with the scope, such that there's no need to disconnect the two (and risk any change of imaging plane) prior to the next session. You can see the images here: http://www.pbase.com/boren/image/148381443 and here: http://www.pbase.com/boren/image/148381439
I Haven't seen this one before. Very nice, welcome to IIS, looking forward to seeing more of your work.
all the best

Thanks Paul!
I find it very cozy around here... It's really a very nice and friendly forum, and I look forward to years of exchanging thoughts, and images, and what not
Cheers,
Harel
