Probably not missing anything. But to be sure to check out the calculators at the www.astronomy.tools site. They are the best. -- Chip Louie Chief Daydreamer Imagination Hardware Astropheric Weather

Thanks a lot :) Yeah, it is hidden by dust, more of challenge and than it "should" be. Part of the local group, if I get it right. I am really really fascinated by these galaxies. Giant systems,? so

Magnus well done! wow, i had to look that one up, i wasn't aware of it. great job -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

Hi! Let me share one as well, produced in the end of 2020. This time not wide field but instead a galaxy - IC 342. C8, with reducer and an ASI294 MC Pro. A little more than 13 hours from suburban

Thanks Brian.

Really great Jim - i love to see these widefields with the integrated flux nebula -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotog

another winner Jim - great color and contrast -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

Here's another. *Horsehead and Flame Nebula* Imaged with a Sky-Watcher 100mm ED Triplet @ f/5.5 and ASI2600MC Pro within the Phoenix city limits - Bortle ~8.? Waning Gibbous moon 61%.? One hundred

Here's one that I like. *M45 Wide Field w/ IFN - SW Esprit 100mm APO + Starizona Apex-L 0.65x FR/FF* Imaged with a Sky-Watcher 100mm ED Triplet, Starizona 0.65x Apex-L Focal Reducer / Field Flattener

There are multiple online calculators for determining this. e..g.: https://www.bintel.com.au/tools/astronomy-calculator/?v=322b26af01d5 The focal length you use is your telescope focal length

Hi Tom I'm not sure what you mean by actual vs apparent. Often the actual focal length is slightly different than the spec of the focal length if you have two cameras with the same pixel *size*, they

Sonny wow, is this still with that atik camera of yours? They should give you an award or something your images have improved 1000% wrote:

Gary, I am unsure if your goal is to be into dedicated AP or if something on the video astronomy side would suit your needs. I've been very pleased with the color CMOS MallinCam DS10cTEC in terms of

I used CCDcalc from new astronomy here ( http://www.newastro.com/book_new/camera_app.html ). You can input your own camera telescope parameters and save them. ?It gives a visualisation of typical

I found the formula for calculating this value but have a question. When using focal length, is it the actual focal length or is it the apparent focal length? I have two different cameras with

Hi Gary, You just dropped a pretty loaded question and the answers will be varied and detailed I'm sure. I don't do planetary, but I think Brian's answer to that is a good one. But for deep sky, you

Sonny, love your image and commentary! I too want to become an accomplished long exposure astrophotographer but unlike you I have a total of 5 months experience. Could you elaborate on achieving

Sorry, probably been seen before, but 2020 changed my Astro Imaging dramatically because I got my GM811GHD mount, and finally ironed out my wrinkles from my bad habits developed from my old mount. But

dang Ken Such detail and rich color. Astonishing this is on a 24 year old G11 -- Brian Brian Valente portfolio brianvalentephotography.com <http://brianvalentephotography.com>

Happy new years folks...Brian hows the covid going with the Losmandy family?? Hope its ok -- Brendan
